1. EXECUTIVE SUMMARYIntroduction:

TCIL was approached by USOF Administrator vide Letter D.O No 30-119-1/2013 –USOF dated1st Nov 2013 for preparing a DPR in accordance with TRAI Recommendations dated Sep 2013for Telecom Infra-structure Augmentation in the North Eastern States including Sikkim andAssam.

TCIL studied the above mentioned TRAI Recommendations. Based on the study and variousmeetings that were held with USOF officers in Nov 2013 the scope of DPR was finalized.

The three verticals addressed in this study report for North East region is as follows:

1. Providing 2G coverage to the villages that are uncovered by any Telecom ServiceProvider (TSP).

2. Providing 2G coverage to the uncovered National Highway (NH) network of North East.3. Providing redundancy and diversity for the optical media from State Headquarter (SHQ)

to District Headquarter (DHQ) and Inter-State capitals connectivity.

This report covers 2G coverage to the uncovered National Highway (NH) network andtransmission media network gap analysis for providing redundancy and diversity for theoptical media from SHQ to SHQ and SHQ to DHQ of North East Region including Sikkim, atotal of 8 States.

The key findings are the quantity and cost required for upgrading the telecom infrastructure inNorth Eastern Region. The detailed of the study with quantity is given in the chapters. Thesummary of estimated cost along with quantity is given below.

3. TELECOM SCENARIO IN NORTH EAST

3.1 IntroductionThe country has seen a phenomenal growth in the availability of economical telecomservices. People from all sections of the population are now using mobile telephone andaccessing the internet for viewing/retrieval of information and e-mail.

However, in respect of growing tele-density, the urban-rural divide continues. TheGovernment of India is determined to bridge the gap between urban and rural areas inrespect of telecom services, because access to voice and data services will play a crucialrole in the overall development and growth of the rural areas.

3.2 The Bandwidth Bottle-NeckThe transport system in North Eastern States is inadequate on many counts to carry thepresent/future levels of rural traffic. The shortcomings include insufficient multiplexcapacity, some areas not having OFC connectivity, use of radio media having inherentbandwidth/spectrum constraints, and, self-healing path protection is not available.

The existing networks are undergoing upgradation/expansion by the various operatorsbut this is in response to the growing commercial requirements, however, suchexpansion would not be undertaken with the objective of increasing infrastructure inanticipation of data traffic requirements that would arise in future years in remote andrural areas also because the software applications are also to be developed and setupfor the traffic to arise.

The solution to inadequate capacity mentioned above, is to deploy appropriatetransport technology in intra-district transport network that will provide cost-effectivehigh capacity. This network will also meet the futuristic requirement in terms oftechnology and the demand for various applications/services.

Other Challenges in rolling out Telecom Network in North East Terrain Difficulties ROW permissions Inadequate Power availability Infrastructure Issues

3.3 Way Aheada. 4G - LTE

The way ahead is the new LTE based 4G based technologies which are already deployedin many countries. Instead of 2G & 3G based towers and equipments, the newinfrastructure should be based on 4G where the tower deployment is easier andcheaper. It is all the more required in remote places like NER where space, power andfunds are constraints as 4G offers solutions addressing all these issues. The 4G BTS arevery small in size and require very less power for operation, approx. 20W. Moreover,they can be installed on poles rather than towers. The 4G network is also roll backnetwork i.e., it supports 3G, Edge, GPRS as well as 2G. The 4G network is based on LTE-Advanced - 3GPP Long Term Evolution. LTE is a series of upgrades to existing UMTStechnology and will be rolled out on existing frequency band.

Therefore in remote areas where CAPEX is an issue along with power availability, theoperators should look at 4G option to make their networks it future proof.

b. Active Infrastructure sharing

Shared RAN is a concept in which one or more licensed mobile services operators agreeto share the radio access network of a third party infrastructure provider, for providingthe mobile telephone services in accordance with their license terms and conditions.The licensed operator would still own the core network and would continue to own andmanage it. The backhaul/transmission system could be on Optical Fibre Cable mediumor Microwave or alternative media/technology and used on a shared basis.

Sharing of passive infrastructure is already taking place between Mobile ServiceProviders on mutual agreement basis, and, third party infrastructure providers are alsosetting up passive infrastructure (BTS sites) for sharing by licensed mobile serviceproviders who pay rental/leasing charges to such third party infrastructure providers.7289 towers i.e. about 99.13% have been set up under shared mobile infrastructurescheme. The infrastructure so created is being shared by three service providers forprovision of mobile services. 15209 BTS’s have been commissioned by Service Providersand mobile services are being provided. This is as per 12th five year plan for Telecom.This results in reduced up-front cost of setting up BTS infrastructure for the serviceproviders since the passive infrastructure cost component is a major proportion of thetotal cost of setting up a wireless network.

The sharing of active infrastructure is the logical next step, and the Department ofTelecommunications (DOT) has now allowed sharing of active infrastructure amongst

12 | P a g e

service providers based on mutual agreements entered amongst them. It is pertinent tomention that DOT guidelines exclude from sharing the allocated spectrum. The activenetwork allowed to be shared is limited to antenna, feeder cable, Node B, Radio AccessNetwork and transmission system only.

Cost savingsActive infrastructure sharing results in both CAPEX and OPEX savings for the sharingoperators.

It is known that passive sharing allows operators to share costs of passive infrastructurewhich is estimated to be almost 60% of the BSS cost. In case of active sharing becausethe BTS equipment, antennas and feeders are additionally shared, the CAPEX savings foroperators shall be more. However multi-operator equipment and antennas are moreexpensive than traditional RAN equipment. But with increased deployment of sharedRAN, the production costs may drop in future.

Also the common equipment platform results in less power consumption and reducedmaintenance costs.The additional savings that may be obtained on account of sharedRAN over passive infrastructure sharing may be estimated from a break-up of site CAPEXstructure.

Item of Site CAPEX (%)

Real Estate 28%

Labor cost/civil/ installation 30%

Base Station 22%

Antenna & feeder 10%

Power supply 5%

Others 5%

Total 100%

From above table it is seen that base station and antenna system account for about 32%of site CAPEX and depending upon the number of sharing operators, significant costsavings of appx. 25% may be obtained for each operator.

13 | P a g e

In case of OPEX the savings shall arise from (a) lease/rental of passive infrastructuresince less space is required to accommodate more operators, and, (b) maintenance andpower consumption. The breakup of operational expenses for RAN have been estimatedas follows-

Item of Site OPEX (%)

Rental/Lease 40%

Backhaul 22%

Maintenance 20%

Others incl. power consumption 18%

Total 100%

Since all above expenses will get shared, the savings in OPEX are expected to besignificant up to appx 10% to 15% of OPEX per operator.

Commercial basisThe commercial basis of sharing should take into account (a) recovery of investmentmade by the third party infrastructure provider in a reasonable period, (b) the annualoperational expenses, and, (c) reasonable returns to sustain and grow the business asalso make reasonable profits.

Factors supporting Shared RANShared RAN may be seen as a new phase of the mobile industry, wherein through theconsolidation and sharing of the radio access network the operators shall be able toimprove coverage in a faster and more efficient manner than if each operator was toroll-out own network. It is also expected that the operators shall be able to providemore types of specialized services in this process.

The various factors that are expected to drive the deployment of shared RAN services inIndia include the following:

Government Teledensity outlook:The Government is having ambitious targets to raise the tele-density in remote/ ruralareas and seeing the remarkable growth, as per 12th Five year plan.

Pressure for cost reduction:

14 | P a g e

In view of the low ARPU, the rollout of mobile networks can only be supported on astrategy of minimizing the cost and time of rollout of the network. The sharing of mobileinfrastructure is the only way to cut down the cost (especially for new operators). Asdiscussed above, passive infrastructure sharing is already taking place in a big way andthe sharing of active infrastructure in light of the recent TRAI guidelines shall be the nextbig thing.

Entry of new players and expansion plans of existing operators:Several major operators, who had been operating more on regional basis, have receivedlicenses as well spectrum in new circles, which would enable them to extend theiroperations on pan-India basis. Also, new licenses have been issued to players such asUnitech, Swan Telecom, and S Tel Limited. Given the significant expansion plans of newentrants over the medium term and the need for them to optimize investments in orderto maintain returns, demand for cell-sites is expected to significantly increase. The newentrants are likely to participate in this shared RAN services since they have to counterthe competition from entrenched players in an environment of low returns.

Technological Consolidation:The shared RAN represents an opportunity for existing operators to optimize andconsolidate their BSS infrastructure in urban and metro areas on a common, high-capacity and scalable platform (including wide-band and efficient IP transmissionnetwork) which shall support the variety of services under 3G/4G with the associatedhigher bandwidths / data-rates. The technological advantage coupled with the necessityof cost savings makes shared RAN solution equally attractive in semi-urban and ruralareas.

4G Spectrum Allocation:It is felt that the process of 4G spectrum allocations may be completed sometime thiscalendar year. The telecom industry is anxiously looking forward to the same. It isexpected that in the initial phase 4G services will be marketed in metro and major cities.However, the cost of migration to 3G/4G remains an important aspect and the sharedRAN network can be one of the solutions for economizing the cost. New technologies tofurther stimulate demand: In order to augment their services, various operators mayplan for providing 4G as well as Wi-Max services as soon as they receive additionalspectrum from Government.

Energy Saving:The shared RAN provides the method of overall reduction of BTS/towers which is in-factbecoming a necessity from the view point of environment and energy saving.

15 | P a g e

Shorter Rollout time:Since the mobile industry is highly competitive, the new entrants face a greaterchallenge from incumbent operators already having widespread network, establishedbrand name and large subscriber base. Third party active infrastructure providers canprovide the economical cost and rollout time advantage which may prove critical forbusiness success of the newer entrants.

3.4 USOF SupportRecognizing that present/near-term revenue derived from carriage of rural/remote areatraffic on the augmented/expanded network may not be adequate to attract therequired quantum of investment, USOF intend to provide financial subsidy support byway of percentage of capital recovery for the five years towards cost of rollout of thedistrict OFC networks in the North East Area. In present report we are calculating theinvestment required (CAPEX) for building the augmented network.

The OFC network up-gradation/expansion in the various states is required to enable theintegrated development of USOF supported service streams, especially the creation ofgeneral infrastructure and induction of new technological developments in the telecomsector in rural and remote areas, and therefore qualifies for financial support from USOFunder the Indian Telegraph (Amendment) Rules, 2006.

4. TRANSMISSION MEDIA PLAN

4.1 IntroductionThe transmission media plays a key role in carrying the bulk data traffic from node tonode. The need for investment in the transmission media in NER has been realized afterthe study conducted by USOF under various schemes both for wireless and wire line. Inone such scheme of USOF for District Headquarter to Block Headquarter connectivity onOptical fiber in a ring topology of 2.5 Gbps upgradable to 10Gbps, the detailed OFCplanning had been done and a business plan for Assam & North East had been preparedby TCIL as consultants to USOF. The financial gap between capital recovery vis-a-viz netrevenue realized over a period of years was estimated. This gap was recognized byUSOF, and the subsidy was provided through tenders floated for DHQ to BHQconnectivity in NER and Assam so as to facilitate telecom operators to rollout thenetwork and mandatorily share it in regulated manner with other operators. BBNL hasalso addressed this issue Block downwards i.e. OFC connectivity from Block to GramPanchayat.

4.2 Status of Existing USOF Schemes in North EastThe projects of OFC connectivity in North Eastern region, below district level have beenassigned to BSNL &RailTel and the work is in progress. The status briefly is as follows:

Status of Project Scheme/ Project Current StatusDHQ – BHQconnectivity on OFCin ring topology.

4.3 Need for State to State & State To District transmission NetworkThe transmission network as stated in the table above i.e. districts downwards isbuilding up under USOF schemes & BBNL project, it is realized that with emergence of3G based applications, video on demand and digital era, huge amount of data shall begenerated by the growing telecom subscriber base. To cater to this voluminous data, arobust network is required from state to district and further inter-state. This studyfocuses on the State to state and state to district part of the transmission network ofNER identifying the gaps in the physical connectivity and capacity wise as well.

4.4 Methodology of Incremental Fiber Requirement for Ring Completion:Keeping the data available in TRAI Recommendations as the baseline, approachfollowed is as given below:

1. Identify the state / district headquarters of North Eastern Region states on a map, as perthe latest data available. This was done using freeware Google Earth.

2. Study of existing fiber network , the references from TRAI, NIC, PGCIL Telecom Network,RailTel Network, BSNL planning sheets having existing and planned fiber information ofoperators in Assam & North East are taken.

3. A physical ring is planned considering the geographical factors i.e. roads, terrain andriver etc. on Google earth both for state to state and state to district for all 8 states ofNER.

4. The gap in the existing and new fiber required to complete the ring is identified. Thenew sections are analyzed against the sections in which subsidy is already providedunder various USOF schemes for Assam & North East Scheme for District To Block HQconnectivity in ring topology.

5. The Sections so identified after above mentioned steps are tabulated against the ringsfor each State.

6. In addition to the incremental fiber identified above, a provision of 10 km. fiber is takenfor inter-operator PoP to PoP connectivity and in case of new sections also, a 10 km.provision is kept for coiling, termination, and maintenance purposes.

4.5 Details of existing Optical Fiber infra-structure:The media augmentation for fiber redundancy and diversity needs to be plannedkeeping the total existing infra-structure of various service providers in mind andidentifying the existing fiber that can be used while planning the diversity andredundancy. The existing fiber routes are referred from TRAI Report (BSNL Network),PGCIL telecom network (PGCIL website), RailTel telecom network (RailTel Network ppt&USOF NE) data available with TCIL regarding existing OFC of various Service Providersand NIC database.

4.6 Backhaul Equipment PlanningThe physical gaps are analyzed above and the backhaul equipment planning addressesthe capacity requirement in the rings planned as explained above. The rings are plannedconsidering existing optical fibre network of all the operators since the network is to beaugmented keeping in mind to avoid redundancy of transmission media on same routeby different operators.

Effect of Existing USOF Scheme

In USOF schemes adequate measures are taken to cover the above high lease costs.

Following deliverables are expected from BSNL and RailTel in Assam and North Eastrespectively:

1. The operator shall build, operate, own and manage all the equipment/infrastructure forthe intra district augmented/created OFC transport network.

2. The operator shall be responsible for complete augmented and created bandwidth inthe district wise OFC networks, covering both existing routes/sections,utilized/upgraded as well as new sections. This responsibility shall be on continuousbasis and will extend to all aspects of the scheme viz., roll-out and commissioning,operation and maintenance, and providing bandwidth on sharing basis.

3. During the validity of the agreement, at least 70% of the subsidized bandwidth capacityshall be made available by the host operator to other service providers for utilization, onsharing basis at discounted tariff as prescribed in the agreement.

4. The discounted tariff for Assam is 26.22% of current TRAI ceiling rate i.e. minimumdiscount of 73.78% on the current TRAI Ceiling tariffs for various bandwidth anddistance slabs.

5. The discounted tariff for NE-I circle is 12% and for NE-II is 27%. i.e. minimum discount of88% on the current TRAI Ceiling tariffs in NE-I Service Area and minimum discount of73% on the current TRAI Ceiling tariffs in NE-II Service Area.

6. The discount is valid on the subsidized bandwidth, provided on lease to other operators,in the OFC transport network from SDHQ-SDHQ, having both the ends in same district orin different districts.

7. The discounted tariff is applicable till the agreement period continuous between USOFand BSNL for Assam and USOF and RailTel for NE respectively.

From above it can be concluded that if BSNL and RailTel has to ensure the bandwidthfrom any District to any District and they have to share it with other operators at adiscounted rate as prescribed in their respective agreements. But their mandate is toensure ring architecture between DHQ and SDHQ. From SDHQ of one district to SDHQ of

another district, they have to only ensure a path, not a protected path. Hence forredundancy in path between State HQ to District HQ, plan has already been proposedabove. It is assumed that 2.5G ADM are available at all DHQs as it is one of thedeliverables to ensure ring of minimum 2.5G expandable to 10G.

State to State & State to District Ring Design

The SDH ring design with an interconnected multi-ring architecture overlaid over anoptical mesh network or on Optical physical network as planned in state-wise physicalrings above. The no. of wave lengths required in any logical ring, is calculated using theadditional bandwidth requirement from the TRAI report. The logical rings consist ofOptical Add/Drop Multiplexers (OADM) and Digital Cross Connects (DXC). OADM isplaced on nodes where a part of traffic is dropped, some traffic is inserted and the restis passing through. Digital cross connects are used to cross connect inter ring trafficbetween multiple rings where inter ring traffic is defined as the set of demands suchthat source node belongs to one ring and the destination node belongs to other ring.Optical Amplifiers (OA) are placed where only signal regeneration and pass through isneeded.

A state-wise equipment plan is formulated and the lease charges wherever requiredshall be extra. We are also assuming that the existing system present is 2.5G SDH is justsufficient to cater to existing traffic need of blocks below DHQ and a separateequipment shall be planned at DHQ for SHQ to DHQ ring. In order to meet therequirement of increasing bandwidth demand on the basis of various applications,DWDM needs to be deployed.

From above it is analyzed that at least 40 lambda, 2.5G, DWDM system shall berequired. The Digital Cross Connect (DXC) is planned at all the state Headquarters and atthose District HQs where two or more rings are interconnecting. A provision of oneOADMat each District Head Quarter is taken while planning. In new sections, an Opticalamplifier (OA) is placed at every 40 km. distance for regeneration of signal. In a ring,when there is an inter operator switching of traffic, an OA is planned at interconnectionpoint. An OA is also planned at nodes other than DHQ in the ring which are at the endpoints of new section. The equipment projections on the rings are analyzed in therespective tables of state.4.7 North Eastern Region Connectivity with rest of IndiaAssam state is the gateway to the northeastern part of India. It is surrounded by theother northeastern states: Arunachal Pradesh, Nagaland, Manipur, Mizoram, Tripuraand Meghalaya. Assam along with these 6 states, together called the “seven sisters”.

19 | P a g e

These states are connected to the rest of India via Assam's border with West Bengal anda narrow strip called the "Chicken's Neck."

Redundant Connectivity of Guwahati with Rest of India (Chicken Neck)

Traffic Routing of North East State And Assam through KolkataAll the telephone traffic generated by BSNL and other operators in these Seven SistersState has to be brought to Kolkata for further routing through the Tax Network. Theentire NorthEastState telecommunication OFC link with rest of India must pass throughthis “Chicken Neck Area”. At present, the distance between Kolkata and Agartala inIndia's landlocked northeast is a staggering 1,700 km Incase of disruption in this routethere is no alternate land route.

Moreover, distance wise this is a long route, subject to greater number of faults. Duringany emergency, the telecommunication is solely dependent on satellite communication,which is not cost effective as well as is a low speed with narrow bandwidth. The OFCmedium would offer a better future solution in terms of expansion of bandwidthcapacity.

In the TRAI report referred, it is mentioned that the OFC route Bongaigaon – Guwahati –Nagaon (350km) which connects Guwahati to the rest of India has been damagedbeyond repair due to road widening work and therefore may be funded. It is to mentionthat subsidy for the same has already been provided in USOF Assam scheme and thissection will also get covered indirectly while connecting these districts with theirrespective sub-districts.

4.8 State to State OFC ConnectivityThe state to state ring connectivity is seen w.r.t Guwahati, where all the traffic routesand table below shows physical ring from Guwahati to the six NE states & Sikkim. It isseen that in most cases existing OFC connectivity is available on BSNL. Some keysections are available on PGCIL, which is a robust & reliable being OPGW network. Thenetwork of RailTel& Oil India (reference TRAI report) is also present as redundant pathon some sections. There are only two new sections from Dhemaji to Dibrugarh andKhowai to Kamalpur in Tripura identified , where new fiber need to be laid for ensuringstate to state interconnectivity , the CAPEX for same is accounted in the respective statetables.

The equipment upgradation planning is done in all State to Districts rings. A Digital CrossConnect is planned at each State Capital which is equipped with high capacity OADMs.

20 | P a g e

The DXC shall be adequate for State to State rings and shall work as an interconnectbetween State to state ring and State to District ring. No additional equipment isrequired at State Head Quarters. Hence, Capex requirement in terms of equipmentupgradation is nil in State to state connectivity as it is already covered in State to Districtrings.

Recommendation for State to State connectivity in North EastThe state to state connectivity analysis has been done and it is analyzed that BSNL OFCnetwork is existing from state to state in NER region. However, redundancy on theseexisting routes is critical as these are bulk traffic carrying routes and generally NER hasdifficult terrain so any fiber damage / cut may take long time to repair.

With this perspective, PGCIL OPGW network along high power transmission line is veryreliable option, it is connecting all state capitals with Guwahati. The details are providedin Table above. As mentioned in TRAI report, PGCIL is not leasing dark fiber but onlyproviding bandwidth and the tariff on these NER routes is also relatively high. This issuemay be dealt by calculating the financial gap and providing subsidy to PGCIL on thesespecific routes. It is essential to create a level playing field in NER and encourageoperators to enter in NER. At the same time PGCIL may reduce its bandwidth leasingcharges to other operators, hence, to reduce unnecessary incremental OFC layout forredundancy network and to utilize the existing OFC in best way USOF may suitablyprovide subsidy support to existing operators for the same to promote improvement oftelecom infrastructure in North Eastern states.

The analysis of the redundancy and capacity for state to state ring is done and thestrategy is tabulated below. As such no infrastructure gap is seen. The issue is highBandwidth lease charges and non-availability of dark fiber by operators with existinginfrastructure like BSNL & PGCIL in NER.

26 | P a g e

4 Assam – Sikkim NIL BSNL & PGCIL fiber is existing fromGuhawati to Gangtok.

Note: The above CAPEX requirement includes cost of OFC (supply + service). The provision ofCAPEX for Equipment upgradation is kept in state to district rings and the same systemshall suffice the requirement of state to state rings.

4.9 State to District Physical Ring Planning

The study of state to district connectivity in ring topology is done for Assam, Sikkim andthe six North Eastern state and it is seen that mostly BSNL is present and manyuncovered sections are already funded in USOF Assam & NE scheme. However, RailTel&BSNL need to expedite the rollout of fiber in the NER and adhere to the timelines given.The incremental quantity of OFC length as analyzed in table below for State to Districtring completion is subject to completion of the USOF Assam & NE scheme.

AssamThe Assam state has 27 districts, and the study is done w.r.t to state head quarter –district headquarter connectivity in ring on OFC, considering the existing fiber of variousoperators. The gaps identified are from

1) Dhemaji to Dibrugarh (70 km) - This is subject to completion of bridge onBrahmaputra river as also mentioned in TRAI report. This section is important frompoint of view of state to district ring connectivity in Assam. Survey may be done to getthe actual length of underground fiber and aerial fiber over Brahmaputra river.

2) Silchar to Diphu - On this section, in parts BSNL(Silchar to Udarband existing),Habagajao – Maibang (subsidy provided in USOF Assam Scheme) andRailTel (Dihu toLumding) is present.The new section length is estimated as Udarband(Cachar) –Harangajao (North Cachar)59 km and Maibang- Lumding79.1km, the total length is138 km. The detailed ring covering the connectivity & redundancy is tabulated in Table 2and the respective KML files are placed at KML-6 to KML 8 in Annexure 1.

The capacity enhancement of these rings is done by equipment planning on 40 lambda,2.5 G DWDM rings , the methodology is explained in 4.6 section.

Recommendation for Assam State to District

The analysis of Assam State to District ring shows that BSNL is the dominant operator. It hasalready existing OFC covering all the districts and most sub-districts under USOF Assam project.As per the project mandate the lease tariff is reduced on these sections. The State to Districtgap in Assam for the fiber & equipment is nominal and BSNL may be directly given subsidybeing dominant operator to complete this gap and mandated to provide bandwidth on lease atreduced tariff.

35 | P a g e

MeghalayaMeghalaya state Headquarter is Shillong and has 11 districts, which includes four newdistricts formed after 2011 census. The detailed study for the ring connectivity betweenShillong and District Headquarters is done using freeware Google earth and existingfiber information from TRAI report under reference and the details of planninginformation conducted for USOF North East Scheme in which rings were formedbetween District to Block HQ on fiber.

In Meghalaya all the district headquarter are connected to Shillong in five rings on BSNLexisting fiber and on the gap sections are already considered while USOF NE planningwherein these sections are subsidized and to be executed by RailTel.

One new Section of 53 km from Riangdo to Bokois proposed and shall provideadditional redundancy to four rings envisaged.

The various rings are tabulated in Table 3 and the respective KML files are placed at KML9 to KML 12 in Annexure 1.

The capacity aspect on these rings are done by equipment planning on 40 lambda, 2.5 GDWDM rings and repeater distance of 40 km is taken on new sections. The methodologyis explained in Section 4.6 Backhaul equipment planning.

DXC at Shillong

TripuraThe Tripura State has Headquarter at Agartala and has 8 districts, including four newdistricts formed after 2011 census. There are 3 rings envisaged from Agartala to itsdistricts which are covered on BSNL fiber and some new sections are alreadysubsidized through USOF NE-1 tender.

A new section required to connect ring between Districts HQ Khowai, Kaliashahar, &Dharamnagar is from Kamapur – Tulashikar (36 km) This section is also identified inthe state to state rings for connectivity from Shillong to Agartala to Aizawl but cost ofthis section is taken here.

The rings are tabulated in Table 4 and are represented in KML 13 to KML 14 inAnnexure 1.

The capacity aspect on these rings are done by equipment planning on 40 lambda,2.5 G DWDM rings and repeater distance of 40 km is taken on new sections. Themethodology is explained in Section 4.6 Backhaul equipment planning

MizoramThe Mizoram State HQ is Aizawl and it has 8 districts in it. The terrain is hilly and roadconnectivity to district headquarter is only feasible through NH. In many cases, alternate pathsare not available, therefore aerial cable is the only way to ensure redundancy in such locations.

The analysis for Aizawl to district HQ has been done, 4 districts namely Serchhip, Lunglei,Lawngtlai and Saiha are connected with Aizawl in ring and sub – rings formed through Serchhip(MZSD - 1to 4), in which two new sections from (Lawngtlai - Saiha (58km) &Sangau -Hnaihthial (62km) i.e total 120 km is proposed.

The other three districts i.e. Champai, Kolasib and Mamit are either partly or fully connected onOFC and to ensure redundancy for these district headquarters aerial fiber is only way becauseof lack of alternate route.The actual requirement of Underground OFC or OPGW orADSS cablecan be assessed only after a detailed field survey.

The new sections suggested to connect these 3 districts in ring with Aizawl are as follows:1) Underground OFC - Aizawl - Lengpui- Mamit, UG OFC (95 km), Aizawl –Champai(100km){BSNL damaged section, reference TRAI report}

2) Aerial OFC Aizawl- Champai (207 km) , Aizawl – Mamit (95km) and Aizawl – Kolasib (80 km).The actual length of aerial fiber may be less and is subject to a site survey. For budgetaryestimation same length as of underground fiber is taken.

The details are given in Table 5 below and the rings are represented in KML 15 to KML 20 atAnnexure 1.

The capacity aspect on these rings are done by equipment planning on 40 lambda, 2.5 GDWDM rings and repeater distance of 40 km is taken on new sections. The methodology isexplained in Section 4.6 Backhaul equipment planning.

ManipurThere are 9 districts in Manipur state with Imphal as its State Headquarter, which isfurther divided into Imphal East and Imphal West. There are three rings planned inManipur to provide state to district connectivity. The details of rings along with map aregiven in Table 6 below.

In the 1st ring covering Ukhrul, Imphal East & West, Senapati and Tamenglong, it is seenthat BSNL ‘s fiber is existing and the gap from Tamenglong to Imphal West via Noney isalso partly covered under USOF NE scheme. The section where new fiber will berequired is from Nongpoh (Tamei Road) – Patsoi (113 km)

In the second ring which covers Bishnupur, Churanchandrapur, Thoubal, the fiber iseither existing BSNL route or partly subsidized in planning of USOF NE, only the sectionof new fiber identified is from Sangaikot – Langching (7.7 km).

The Chandel district has linear connectivity on road, and while planning the District tosub-district scheme for USOF in Manipur, BSNL existing network in Chandel wasconsidered. The fiber route from Chapikarong – Chandel is identified as new fiberrequired and already subsidized in USOF NE planning.

The respective maps are given in KML 21 to KML 23.

The capacity aspect on these rings are done by equipment planning on 40 lambda, 2.5 GDWDM rings and repeater distance of 40 km is taken on new sections. The methodologyis explained in Section 4.6 Backhaul equipment planning.

DXC at Imphal West

NagalandThe Nagaland State has 11 districts with state headquarter at Dimapur. BSNL‘s fiber isreaching all the districts as appears from the NIC database and TRAI report referred. Therings are planned to provide route diversity to all the districts with state headquarter atDimapur. In the four rings planned as shown in table 7 below, there are two sections wherenew fiber is required are as Zunheboto – Akuloto (30 km)– BSNL damaged section as perTRAI report and Mon to Longleng (84 km). Peren district is already linearly connected withDimapur as per NIC data; however it is also covered in USOF NE planning where it is SDHQ ofKohima and a ring is planned through it. As per Google earth no direct road connectivity isappearing but as fiber km is subsidized and so the selected operator for NE i.e. RailTel shallprovide connectivity on alternate media i.e. fiber or microwave.

The respective rings are given as KML 24 to KML 26 in Annexure 1.

The capacity aspect on these rings are done by equipment planning on 40 lambda, 2.5 GDWDM rings and repeater distance of 40 km is taken on new sections. The methodology isexplained in Section 4.6 Backhaul equipment planning.

Arunachal PradeshThe Arunachal Pradesh State has 16 districts, with Itanagar as its capital. It has got difficultterrain not all the districts can be planned in ring to have redundant routes. As ArunachalPradesh has difficult terrain, laying of OFC may not be afeasible option. Therefore option forlaying aerial OFC either on OPGW orADSS based technology has to be explored. The actualrequirement of Underground OFC or OPGW orADSS cable can be assessed only after adetailed field survey.

There are 6 districts which have to be connected on linear path on fiber and routeredundancy on fiber can only be obtained by laying aerial & u/g fiber both on the sameroad. These districts are Anini, Hawai, Yingkhiong, Koloriang, Bomdila & Tawang, some ofthese are already considered in USOF NE planning and so fiber is subsidized under USOF NEscheme. In the remaining new sections required are: Along – Yingkiong (220 km. – u/g &aerial) and Dirang –Jang (107 km)

The rest of the districts are planned with Itanagar to Tezpur ring via Assam and a sub-ringaround Tinsukia to cover Changleng & Khonsa DHQs. The details of rings are given in table 8below.

New Sections required as analyzed using TRAI map, NIC and USOF NE & Assam Schemesring-wise are:

Ring for Itanagar, Ziro, Daporijo, Along, Pasghat, Roing, Tezu has following new sectionsas Along – Pangin (75 km), Pasighat - Dambuk (58 km)& Tezu - Parsuram Kund (45 km)

Ring for Changlang & Khonsa DHQs has new sections as: Margherita - Namtok (19 km),Chnaglong - Khonsa (117 km) and Khonsa- Deomali (46 km) .

Ring for Seppa DHQs has new sections as : Nirjuli - Pakke keshang (102 km) , Seppa _Bhalukpong (T point) (125 km), Bhalukpong – Chariduar (31km)

The capacity aspect on these rings are done by equipment planning on 40 lambda, 2.5 GDWDM rings as per the methodology explained in previous chapter under “Backhaulequipment planning”.

SikkimThe Sikkim state has 4 districts viz. North, South, East and West Sikkim withheadquarters at Mangan, Namchi, Gangtok & Geyzing respectively. Gangtok is the statecapital. The updated data of underground fiber in Sikkim is not readily available. As perTRAI report, the new fiber required is between Mangan to Geyshing (115km) and thering is formed connecting all the four districts Gangtok – Namchi – Geyshing – Mangan –Gangtok. The same is considered for CAPEX estimation here.

The equipment planning capacity is done for the ring above with one DXC proposed atGangtok, 3 Optical Add Drop Multiplexers (OADMs) at the rest of three headquarters,and 2 (Optical Amplifiers) OAs at the new fiber route (repeater distance 40 km. taken ).

Recommendation for North East - State To District Ring ConnectivityThe analysis of state to district rings in the six NE state and Sikkim shows that mostly fiberexists on BSNL and the rest of the sections are already funded in the USOF NE project. Somekey sections are also available on PGCIL OPGW network as given in tables above. The fiberfunded under USOF NE project is however subject to rollout completion by RailTel. Toprovide the bandwidth availability at nominal rates for state to district ring connectivity insubsidy may be provided and one of the following approach may be taken:

The existing dominant operators BSNL,RailTel and PGCIL are provided additional subsidyon their existing sections and for new fiber and mandate the bandwidth lease at lowertariff. The incumbent operators may sign an agreement among themselves so as makeuse of the existing fiber of each other (fiber swapping / bandwidth swaping).

The factor of lease on entire existing fiber on IRU basis may be taken and including thenew fiber laying cost while calculating the subsidy and provided through tender to anyoperator who provides bandwidth from state to district at reduced tariff as prescribed inthe tender. This will ensure a level playing field for all operators.

81 | P a g e

4.10 CAPITAL EXPENDITURENorth East region has generally tough terrain and subject to problems of landslidefiber cut, and some remote places are naxal and insurgency prone area. Thereforeoption for laying aerial OFC either on OPGW or ADSS based technology has to beexplored. Though per KM cost for OPGW cable is Rs 3 lakh, ADSS cable is Rs 5 lakhand underground OFC rate varies from section to section depending on soil (rocky,soft & hard) in NER, however, for budgetary investment requirement an average costof Rs 8 lakh per KM is taken. It does not include RoW, as it varies from state to state.

The estimated cost in the table below is the new fiber required to complete physicalrings required between state to state and state to district less the existing fiberavailable as per NIC and TRAI report and the sections where subsidy is alreadyprovided through USOF Assam & NE schemes for District to Sub district connectivity.The actual requirement of Underground OFC or OPGW or ADSS cable can beassessed only after a detailed field survey.

Note: The OFC laying cost Rs. 8 lakhs per km taken is a budgetary cost. Although thesupply cost of 24F OFC is approximately Rs. 48,000 per km but the commissioningcost varies depending on the terrain and ROW. Hence due to difficult terrain thesupply plus commissioning cost of OFC is taken as Rs. 8 lakhs per km excluding RoWcharges. The above cost includes all taxes and duties except Octroi and local taxes.

For OADM cost, it is assumed that 40 lambda ROADM costs around $ 11000 i.e. approx 7 lakh plus for dropping/adding 2 lambdas, 4 transponders are required.The cost of each transponder is approx 1.5 lakh. Hence we assume a total cost of 15 lakh for 1 OADM for budgetary purpose. Actual cost shall be arrivedthrough tender process. Optical Amplifier shall wok as a regenerator and it is deployed at stations where distance between two OADMs has exceede d 40 Km.The budgetary cost is taken as 5 lakh per OA. Digital Cross Connect (DXC) is assumed to be of 40 lambda capacity. The functionality includes OADM and Interdistrict ring traffic routing. Cost is taken as Rs 1 Crore per DXC as budgetary estimate. All the above costs are inclusive of taxes and duties except Octroi andlocal taxes.

4.11 OPERATING EXPENDITURESuccessful telecom business is very much about keeping operation and maintenancecosts low. Depending on network design, the maintenance and operations can bemore complex, more labor intensive, more prone to human mistakes and thereforemore costly.

With the robust growth of SDH worldwide, many O&M issues have arisen. Inparticular, commissioning and maintenance of equipment is a critical issue.Maintenance involves routine maintenance and fault locating.

4. 11.1 Operating Expenses

The operating costs depend upon the organization structure and the nature of workcarried out. The operation and maintenance has been organized under two mainheads namely Establishment & Manpower. The establishment head includes thebelow listed items:

o Office Rent/ Lease.o Electricityo Securityo General Maintenance, Water Charges, cleaning, Miscellaneous, Staff Welfare

etc.o Telephone, Fax, Internet, Conferencingo Bandwidth costs for Office Operation incl. NOCo Stationary , postage etco Vehicle

4.11.2 O&M manpower

O&M teams and their functions

The O&M office will administrate number of equipment and OFC maintenanceteams. O&M implies following functions/activities:

Preventive maintenance Breakdown maintenance Configuration/ re-configuration/ upgradation/ expansion Arranging for shipping of defective equipment for repair Arranging to up keep test and measuring equipment, their repair and

calibration Periodic functional and electrical testing as required

The O&M team personnel shall also supervise and carry out acceptance testingin rollout phase. The strategy should be for commercial utilization to begin as

84 | P a g e

soon as parts of networks are rolled out. This requires advance planning withindustry, stake-holders, and potential customers and initiate ‘soft launch’ whichmeans running live traffic and services without charging and helps to de-bug theequipment and processes and builds up customer confidence.

OFC team composition

The planning of OFC teams is done on basis of approximately 250 km OFC spreadper maintenance team.

Planning for 4 hour or 6 hour average restoration time in rural areas wouldmean very high cost of operating expenses and about 12 hour typical restorationtime would be economically possible comprising of average 6 to 8 hourtravelling time and 4 hour splicing time subject to weather conditions and otherlogistics. 6 to 8 hour travelling time implies travelling distance of 240 km approx.Therefore Splicing technicians are planned, each supported by two semi-skilledworkmen for cable handling etc. Based on above discussion total personnelproposed are:

Splicer – 1 Workmen – 2

Equipment team composition

The equipment team planning is economically done on basis of 1 team per state.This distance is not too much considering that NOC can also do many control,monitoring and configuration functions.

Each team will be responsible for the assigned state head quarter and the all thedistricts headquarters of the state including the ring configuration.

For routine maintenance at SDH node like battery up keep, attending to powersupply faults, minor intervention in equipment it is proposed to have oneengineer/team.

Based on above the total personnel proposed are:

Dy. M/ A.M. (SDH) – 1 for a state Engineer (Diploma) - 2 Technician

Recommendation on OPEX

The costs given above for OFC & Equipment maintenance team are per team annual costs. Since the new OFC planned in transmission media issparsely spread and is not on a continuous stretch, a separate team provisioning for maintenance of the same shall be uneconomical. In mostof the cases the dominant operator in a state shall be rolling out the incremental OFC and the existing O&M team and resource s shall sufficefor the maintenance of the incremental part. The O&M costs being high in North Eastern States, adequate provisioning of this may beconsidered while calculating the subsidy component.

However, BSNL and RailTel under USOF Assam & NE projects have already been allotted subsidy which has considered the high OPEX costs.Therefore this shall cover the state to state & State to district portion also. As same fiber & equipment maintenance team may be used tomaintain the infrastructure.

5. COVERAGE FOR UNCOVERED NATIONAL HIGHWAYS (NH) OF NORTHEAST STATES OF INDIA

5.1 Introduction:Based on the TRAI Recommendations dated Sep 2013, in this chapter analysis is done forproviding 2G Coverage for uncovered NH of NE states which include Assam, Meghalaya,Manipur, Nagaland, Tripura, Mizoram, Arunachal Pradesh. The state, Sikkim was alsoconsidered for arriving at the CAPEX for the same.The NH network in the above mentioned states is of 8480 Km in length (Reference Ministryof Development of North Eastern Region; http://www.mdoner.gov.in/content/national-highways). As per data available at NIC it is found that 1272 Km of the Highways has no 2Gcoverage which is 15% of 8480 Km of highway. The NH no. 229 of 1090 Km length inArunachal Pradesh could not be located in the NIC database hence extrapolatedconsidering 3 Km per BTS with the assumption based on 50% area uncovered as per TRAIreport. The state wise detail of uncovered NH is given below in tabular format.

It is mandated by TRAI that there be complete 2G coverage on the National Highway network ofthe above states in North Eastern region. Bench marking of BTS requirement along with itscapacity and infrastructure cost has been studied and reported below. GSM was taken for study asthe same is wide spread in NE area however the TSPs can use CDMA technology also.

5.2 Assumptions:The assumptions used to arrive at the CAPEX required for providing the NH 2G coverage are asgiven below,

a.) Requirement of BTS is calculated irrespective of any particular operator.b.) Though coverage are to be given on Highways but keeping in mind the topography of

North east area Highways were treated as dense forest and hilly areas where line of sightis limited to maximum of 2.5 Km on the Highways.

c.) Cost of Land is considered on rent basis.

5.3 References:The reference documents used are,

a.) TRAI recommendations dated Sep 2013.b.) Report on USOF scheme for uncovered villages and National Highways.c.) The current 2G infra-structure data of various service providers available on NIC GIS

system.d.) Cost Reference: Vendor costs, Ministry of Renewable energy and BSNL tender No

CA/NOW-CM/LWE-BSS/T-445 for setting up of 2G infrastructure.

5.4 Methodology:The GIS data was studied and analyzed and based on design guidelines the numbers of sitewere arrived at.

BSS planning

While planning, low power BTS (micro BTS) were considered in more numbers as Grid powerrequirement is the key factor for areas without or inadequate grid power. BTS was categorizedbased on distance to be covered followed by antenna height and wattage rating of TRX.Limitation of DOT for maxim um radiation of 43 dBm was taken care and thus distance waslimited to 2.5 KM (each side) at maximum though the topography of North East was the mainconstraint for small distance coverage. For radio propagation calculation Okumura-Hata model(GM 1800MHz) with dense forest and inside vehicle signal strength was considered.

92 | P a g e

Two types of BTS were taken defined by Type A and Type B. Type A is of low power BTS withmaximum 10 watt TRX radiation having antenna height of 30 meters. Type B BTSs are outdoorBTS for larger coverage having maximum TRX radiation of 20 watt with antenna height of 40meters. Below table shows the details. Advantage to type A BTS is it low power consumption andType B BTS advantage is longer coverage with 40 meter antenna. Field survey shall decide theTRX power and where ever possible TRX power radiation may be reduced below rated wattage soas to avoid unnecessary radio radiation. For all types of BTS, nos. of TRX was calculated keepingGPRS/EDGE provision of at least 128 Kbps. Below given are the BTS categories with respect toAntenna height and TRX watt rating. For deriving required TRX value for a particular sitefollowing are assumed.

1. GoS (Grade of Service) = 2%.2. Call rate= 100 calls per hour in TCBH.3. Erlang required= average of 25 milli Erlang per call.4. Erlang table B used for channel calculation.

Note: The above categories are derived using Okumura-Hata radio propagation model for1800MHz GSM considering Dense forest, considering actual design criteria.

For BSC planning micro BSC’s ware considered for lesser power requirement and portable size.Such BSC’s have upto 50 TRX capacity and can be easily commissioned at remote sites like NEarea. Cost of BSC along with its power requirement have been build up on BTS cost on per TRXbasis. Similarly cost of OMC-R is also build upon BTS cost. There is no need for a separate NOCto be established.

93 | P a g e

Antenna requirement are to be decided after site finalization. Hence in all the above BTS typesantenna may be Omni, Directional or Sectorial type depending on the tower location. Suchdesign can be implemented by using splitters as required. Site survey along with feasibilitystudy will decide the exact tower location which in return will decide the actual antenna heightand required TRX radiation power. Issues like land acquisition, statutory permissions, views ofinhabitants will also influence for site location feasibility study.

Back haul channelBack haul channel requirements have also been shown in analysis result. As TRX requirement islimited to 4 nos. at a site, hence dedicated E1 connectivity is not recommended for a single site.Moreover on highways E1 is available in plenty hence connectivity of BTS with nearby BSC willnot be a problem. Also it is found that absence of any operator’s 2G services is not more than a25Km in a single stretch. Hence only the last mile optical cable laying may be required. Thus incost estimate we have taken cost of one splicing point and 1 KM of optical cable laying, so as toreach the nearest POP.

Power calculation

Power calculation was made based on Battery (with 3 days autonomy for Type A and 1day Autonomy for type B), Solar and Diesel Generator set. Use of Renewable EnergyTechnology (RET) Solar is taken as mandatory at all locations. In India the annual global solarradiation is about 5 KWh/ sqm per day (for NER it is 4 kWh/sqm) with about 2300-3200 sun-shinehours per year. Solar radiations represent the earth’s most abundant energy source. Theperennial source of solar energy provides unlimited supply, has no negative impact on theenvironment. The solar photovoltaic (PV) modules convert solar radiation from the sun intoelectrical energy in the form of direct current (DC). Converting solar energy into electricity isthe answer to the mounting power problems in the rural areas especially for remote areasof North East region of India. Solar Photovoltaic Cells (SPV) system gives quality power out-putof 48 volt DC to charge directly the storage battery or provide direct power to telecominstallations. BTS will be powered through battery and the charging of the battery will be madewith a combination of both Solar and DG set, solar being the first preference. It isrecommended to use Tubular GEL VRLA batteries as they provide better performance under thepartial state of charge having slow rate of discharge performance ideally suits rural applications.

To make auto switching and load shearing cost of Charge Control Unit (CCU) with inbuilt SMPSRectifier, Solar Junction Box, Remote Monitoring and cable cost (both AC/DC) were taken.

Infrastructure

Under infrastructure category Tower are all considered to be of Ground based narrow baseMast/ Pole tower of 30 meters and Angular GBT with wide base of 40 meter height. Both typeof tower are required to with stand wind speed of 180 km/hr. For hilly area of North East regionerection of angular tower are time consuming and difficult job hence number of angular towerwas kept low. Angular tower was suggested for addressing issues like multiple service providersharing common infrastructure. In most of the cases the effective tower height will depend onthe tower construction site altitude with respect to the target area to be covered. For costingpurpose angular tower and narrow based mono pole was consider in equal numbers. It’srecommended that tower design should be based on TEC GRs or as per design approved froman organization like Structural Engineering Research Centre (SERC)/ TEC/ IITs for structuralfitness, safety, load bearing capacity, ability to withstand wind speed etc. along with antennacost, cost of shelter along with fencing cost was consider for calculation of overallinfrastructure cost.

Other cost like transportation, Commissioning and Installation cost was also included in theCAPEX estimation.

System configuration

The system uses centralized power plant, battery bank, SPV and diesel generator set. All theseare centrally controlled by a Charge Control Unit (CCU) for optimal powering utilization ofsystems and charging of the battery bank. The CCU ensures smooth operation of the overallpowering arrangement without any manual intervention. Its design will ensure optimal energytransfer from the SPV system using MPPT (Maximum Power Point Tracking) technique andautomatic switching on/off of DG set on the basis of battery charge condition. For designpurpose, Depth of Discharge (DoD) for the battery is taken as 80% of its capacity and the DG setis consider to trigger only when battery is discharged below 40% of its capacity. Suchcombination will make optimum uses of diesel and hence cost saving along with lower level ofpollution is taken care off.

The above table shows the National highways running in states of North East and the type ofBTSs required for seamless 2G coverage on the highways with the latitude & longitude details.

All highways are covered with BTS of two categories: A & B. The BTS details with its antennaheight, number of TRX and sector requirements is given in a table above. The cost referencetaken and break down item wise is shown below. Battery autonomy is taken for 3 days for BTStype A and for 1 day for type B. Capacity of battery was calculated considering solar and dieselgenerator set to be as backup for battery charging where solar charging will be given priorityover DG set. On an average sunshine was considered to be for 6 hours a day and the Depth ofDischarge (DoD) for the battery is taken as 80%. Battery when discharge below 40% of itscapacity will trigger the DG set provided that there is no solar charging available at thatmoment. Such circuit design is possible through CCU/DCPDB board and automatic change overswitch.

Cost of sites with respect to BTS type and total number of BTS types is given below.

5.6 Key Observation:

It is observed that due to low availability of power source in remote areas of North Easthighways the cost per site increases many folds. It may be observed that the cost of BTSis only some 10% of site cost. The maximum of the cost is contributed by power systemhaving both solar and DG sets. Hence BTS power rating would be a key factor on theoverall budget estimation. Hence it is suggested to go for maximum numbers of lowpower micro BTS instead of conventional BTS. Conventional BTSs are to be used whereever range of coverage is required more. Such arrangement in return will save more onthe power back up part and thus will be a better feasible solution for sites with very lowreturn on investment (ROI).

5.7 Recommendation

In addition to the CAPEX above, there is a huge recurring investment required tomaintain this infra structure in the form of Fiber and equipment maintenance. As theNorth eastern Region has tough terrain and currently the tele-density is low, operatorsdo not see a lucrative business model or rate of return in this part of the countrybecause of the gap in huge investment of capital and operational expenses vis-à-vis therevenue earned. Therefore there is a need to cover operating costs also; this willencourage operators to provide keep providing services in NER.

The CAPEX as estimated above for the BTS deployment on uncovered highway may befunded by USOF. This will encourage operators to establish infrastructure. As OPEX isalso very high in NER, the same can be factored by taking the net revenue (i.e. Revenue– OPEX) while calculating the subsidy. On an average OPEX per year is taken as 20% ofcapex cost. Such cost includes AMC costs, manpower, drive test and optimization,regular site maintenance, diesel etc cost. It is to mention in earlier schemes of USOF,passive sharing of towers is mandated. However, as per current guidelines active sharingof RAN is also allowed and the main advantage of this technology is the reduction inCAPEX and OPEX as both active and passive component is shared by operators. Thesubsidy calculation to fund the gap may consider this technology and mandate theactive sharing of RAN.
