Conclusion:NoIssuesReasonSolution

1TCH CongestionTraffic Load or Congestion on Bagh City BTSCurrent Site Configuration is S2/2 which is not sufficient so TRX expansion is recommended (S3/3).

2VSWRKana Mori Sector 2 was not working due to high VSWR that is 2.01. Problem was detect on Sector 2 Antenna B tower jumper.New Antenna Jumper has been installed current value of VSWR is 1.30

3Reflected SignalKanna Mori Sector 1 face was towards a hill hence causing a reflected signal problem.Antenna Azimuth is changed from 135 to 140 degree.

3BCCH ClashAdjacent sites have same BCCH that is ARFCN 9 on Bagh City BTS and Kanna Mori BTS.Kana Mori BCCH ARFCN 9 on sector 2 is replaced with ARFCN 3.

2TCH CongestionTraffic LoadSite Up gradation, Expansion or New Sites

3InterferenceCapacity Sites are created by using 900MHz band instead of 1800MHz.Sites are two close to each other thus causing interference.Due to limited frequency Band Overall noise floor has increased which is degrading Voice Quality.Short and Single MA List gives less hopping gain and causing interference.Ideally 1800MHz band Should be used instead of 900MHz which required 1800Mhz DDPU and 1800MHz Frequency Band.25 ARFCNs are not enough to implement a better frequency plan. Impossible to achieve C/I> 15db.

4HSN ClashMore than three adjacent sites were running on same HSN.(Plangi, Budhal Sharif and Loe Dandi)New Frequency Plan have been implemented.

5Non Hopping TRXNo Hopping at Plangi Sector 3Hopping implemented.

6Handover Failure, Call Drop and Call dragging Due to high congestion when at cell boundary MS try to Handover call dragging happens because no traffic channel is available free to transfer call. Which results poor Rx Quality because of low Rx level and later on call drop.Site Up gradation or Expansion

7Coverage HolesNo Site between Plangi and Renkri.A new site is required to fill the coverage holes between Plangi and Renkri.

8Neighbor DefinitionsHandover Between Badal and Renkri is not defined.Handover Between loe Dandi and Renkri is not defined.

New Neighbor Definitions Plan have been implemented.

9Electrical TiltElectrical Tilt feature is not available in existing antennas. So coverage in vertical domain cannot be shrink.System need to be upgraded.

10Sites installation without using any Simulation Planning ToolAll sites are installed without using any Simulation Tool (Antenna Height, Antenna Type, Azimuths, Tilts, and Power Budget). Its so difficult to understand Radio Frequency random behavior without using and Simulation tool.Because of this Main Loops are interfering with each other which cause frequent Handovers and Bad Rx Qual.Exiting tool Mentum Planet and Clutter files are outdated and prone to inaccuracy.New Updated Simulation Tool should be purchased or at least Huawei RF Team help should be taken in order to re-plan Renkari, Kalsan and Loe Dandi.Re-planning may reduce Revenue because high call drop rate gives high revenue but at the same time poor user experience.

11Outdated Expired EquipmentExpired equipment is also responsible for bad Rx Quality.Huawei BTS 3900 should be installed.

Rawalakot City Drive Test ReportRx Level Sub:

Rx Qual Sub:

Conclusion:NoIssuesReasonSolution

1Indoor CoverageOutdoor coverage of Dhamni BTS is very well but indoor coverage in Rawalakot 429 Company Old building is very poor that is around -90dbm to -100dbm due to building construction material and thick walls.Although indoor coverage in new building is good that is around -80dbm to -85dbm.Indoor signal booster, Amplifier or repeater is recommended.

2Roaming IssueUfone and Zong site are very close to Rawalakot 429 company that is approximately within 100 meters. Due to low signal level in Rawalakot 429 company old building all users are on Roaming due to high signal strength of Ufone and Zong.Indoor signal booster, Amplifier or repeater is recommended.
