30

How reliable is NetPrecis?

•Very! Netronics has unrivalled reliability:• Industry standard failure rates typically exceed 4-

5% per annum• NetPrecis average is less than 1.2% per annum• NetPrecis 2008 average failure rate was 0.76%• With zero out-of-box failures in 2008

Despite less than optimal conditions:• Mud huts• Sand and dust storms• Without air conditioning

Neteronics has one repair technician who uses less than 25% of his time for the global NetPrecis install base

31

NetPrecis reliability: superior performance comes as standard

•The NetPrecis reliability cannot be beaten. • 0.76% failure rate, compared to 4-5%

industry norm• Zero out-of-the-box failures in 2008

With an installed base approaching 10,000 units

• MTBF, based on returns to factory, is 95.72 years

This performance is more remarkable considering the harsh conditions our radios are often deployed in, from radios bolted to mud brick walls, in hot and dusty conditions with no air conditioning, through to the extreme cold of the arctic tundra.

Netronics achieves this reliability because of its design excellence, testing and quality assurance, and commitment to continual improvement.

32

More about our testing and quality assurance

•Every single NetPrecis radio manufactured completes an extensive test suite and quality check, including a 15 hour thermal cycle test.

• Several aggressive thermal ramps between -10 and +50 degrees Celsius

• Performance data is automatically monitored and recorded throughout, and analysed at test completion

Why do we insist on this rigorous level of testing?• Thermal ramping is one of the toughest tests for the

RF and oscillator circuitry that is core to the radio’s performance

• Temperature changes are one of the most common causes of early life failures in the field: this has been eliminated for NetPrecis

Examining and testing all aspects of the assembly and performance is apparent in the NetPrecis unbeatable reliability. For us, a high level of reliability is not an added bonus: it is mandatory.

34

Sub-3 GHz advantages

•Operating in the sub-3 GHz spectrum space provides significant advantages, supporting links over extremely long distances or challenging paths not achievable above 6 GHz: the result is carrier-class performance with a lower total cost of ownership.•Greater linking distance:

• Reduced path loss and greater system gain• Less absorption by obstructions or weather events

Environmental effects:• Near non line-of-sight or shaded paths: with carrier-class results• Fades from rain or Harmattan are negligible, and ducting is considerably

reduced

Reduced infrastructure and maintenance:• All indoor mounting means reduced maintenance• Considerably lighter antenna systems, with reduced tower loading and

rigidity: a wooden pole may be sufficient

35

Precipitation: rain fade

•Rain fade is a well known problem in microwave linking. The absorption or scattering of radio frequency energy by rain drops leads to attenuation of the receive signal: noticeable in an increasing scale above 4 GHz frequency operation. In a storm, typhoon or cyclone over a40 km path at 10 GHz, there is 100 dB of rain fade, 30 dB at 7 GHz, and 0.5 dB at 2 GHz.

•At 7 GHz the link is lost, at 2 GHz there is still 5 x 9’s availability!

36

Harmattan and Khamsin

•Dust and sand storms result in a haze-like effect, catastrophic for higher frequency microwave:

• Fades double during Harmattan• Each fade is two to three times the

depth• Significantly reduces availability and

possible path distances• Causes temperature inversion and

duct entrapment for higher frequencies

This occurs most often in Africa and the Middle East but also affects Australia, China, Mexico, Mongolia, Morocco, Russia and the USA great plains.

Sub-3 GHz frequencies are essentially unaffected. At 10 GHz, a typical harmattan fade is 1.8 db per km (30 km = 54 dB). At 1.4 GHz there is less than 3 dB fade for the same path, so it can be ignored.

37

Obstructed paths: the NetPrecis advantage

•Typically point-to-point linking requires obstruction-free paths: this is not the case with the NetPrecis. Linking near non-line-of-sight paths is often achieved, providing carrier-class communications where legacy analogue radio or VSAT were considered the only option. There is no magic, the obstruction type is important and every link needs to be engineered with precision to get maximum performance.

Obstructed paths: the NetPrecis advantage

•The NetPrecis advantage comes from:• 20 years of design focused on quality and stability in the RF platform,

combined with the latest componentry• Use of advanced signal correction: multi tap adaptive equalisation to

remove phase distortions and the affects of diffraction• Forward error correction: to resolve any resulting errors

Netronics engineers can design the optimum solution for the application, allowing in excess of 20 dB obstruction – others will recommend 0 dB.

Challenging link to offshore floating platform

•The requirement:• Establishing a high capacity,

always-on connection with SEPOC’s floating storage and offloading (FSO) facility, 7.2 km off the coast of Yemen

The challenge: • Over-water link, with associated

problems of multipath and signal fading

• 360 degree rotation of the 350 metre long FSO about a fixed mooring facility

• Constant pitch, roll and height variations with tides, currents and weather

• Tidal changes and FSO loading variations causing changes to relative height of antennas above sea level

Challenging link to offshore floating platform

• Conventional solution:

• Antenna tracking system with high gain narrow beamwidth antennas

• Expensive and unreliable due to corrosion of moving parts: regaining lost signal takes time and reduces link availability

• NetPrecis hitless space diversity solution:

• Two omni-directional antennas at separate sites on FSO, made possible by use of low frequency 2 GHz band

• Two directional parabolic grid antennas at onshore site, with wide beamwidth to cover 900 metre movement of FSO tanker

The result:

• 24 Mbit/s Ethernet capacity delivered

• Constant link with no traffic errors, despite pitch, roll and height movement of FSO

Reduce deployment time and cost with grid and Yagi antennas

•Lightweight grid type and Yagi antennas can be used with sub 3GHz bands instead of the solid parabolic antennas used at higher bands, with significant cost and time benefits:

• Expensive towers can be replaced by cheaper pole mounts or guyed masts

• With minimal support needed, site acquisition can be much simpler and quicker

•Why? Because grid type and Yagi antennas weigh much less than solid parabolic antennas and are significantly less affected by wind force.

Whatever the industry, whatever the application, Netronics has a story to tell…

63

Infrastructure bypass in mobile market

•Before the NetPrecis, the backhaul capacity consumed in rural locations propagated

back through the network, accelerating backhaul congestion and reducing the

economic viability of remote base stations. The NetPrecis provides long distance links

with minimal capital expenditure and spectrum fees, bypassing existing microwave

infrastructure and preserving high frequency bands for use in bigger urban markets.

64

Fully integrated mission-critical backhaul for Meralco

•Meralco, The Philippines’ largest electricity utility, needed to support its mission-critical traffic for real-time monitoring and control. Multiple sites had to be linked, and the system integrated with Meralco’s existing IT systems.•Over 60 NetPrecis links in the 1.4GHz band were deployed across the country, building in redundancy for every link. The network has resulted in reduced spectrum licensing costs, improved network management and better reliability.

65

Fully integrated mission-critical backhaul for Meralco

•The Meralco network is made up of NetPrecis radios and NetPrecis expansion shelves. Services are digitised, multiplexed and cross-connected onto E1 bearers using the expansion shelf at the central site and transported to the various sites as digital traffic over the Meralco transport network. The NetPrecis radio provides not only the transport for E1, but also the de-multiplexing of the basic services at the end points.

66

Rural broadband for Sri Lanka Telecom

•Sri Lanka Telecom needed a rapidly deployed access solution for rural corporate

customers, having previously only been able to provide a single V.35 interface. The

NetPrecis was deployed in the 800 MHz band, providing:

• V.35 interface, plus

• 2-wire voice, including payphone signalling, plus

• E1, Ethernet, RS-232, 4-wire voice

The NetPrecis enabled Sri Lanka Telecom to increase the range of services available,

increase revenue opportunities and acquire new customers.

67

Backhaul of surveillance video for Slovenia’s forests

•Slovenia is a highly forested nation, with woodland covering more than half of the territory. Fires are one of the country’s biggest threats, and the government wanted to implement an early warning system.•The NetPrecis was used to transport surveillance video from high definition IP cameras, providing the capacity, security, link distance and near non-line-of-sight capability needed.•Further ‘firewatch’ network extensions are being planned.

68

Remote voice and data for Dhiraagu in the Maldives

•Dhiraagu wanted to increase revenues through increasing the capacity available to remote resorts, as well as reduce operational expenditure by replacing existing outdated and low capacity network equipment technology. •Using the NetPrecis in the 600 MHz band, with its Ethernet and E1 interfaces, Dhiraagu delivered Internet, telephone and LAN interconnect services.•As well as retaining existing customers, Dhiraagu secured business from new resorts, despite the emergence of a new competitor in the market.

69

VSAT replacement in mobile market

•Before the deployment of the NetPrecis in Indonesia, the operational expenditure of satellite as a backhaul solution was exceeding US$31K per month for a 4E1 capacity. •With NetPrecis used as a terrestrial alternative, operational expenditure was eliminated and the link had a return on investment of less than six months.

70

Remote broadband for Telecom Fiji

•Telecom Fiji needed to link 37 offshore resorts and islands to the mainland, despite the challenges of transmission over water, tropical vegetation, and long distances, up to 75km, to generate new revenue streams.•Using NetPrecis in the 1400 MHz band, with its forward error correction and adaptive equaliser to combat multi-path interference, Telecom Fiji achieved reliable broadband Internet speeds of up to 512 kbit/s, with multiple phone / fax lines, providing a range of services including VoIP, VLAN, VPN, video conferencing, PABX, POS and web hosting.

71

Private network for PT Kereta Api - Indonesia Rail

•With 571 stations and 6,000 km of track over a large area, PT Kereta Api needed a safe and reliable communications solution, carrying PBX telephony, private mobile radio, train control signalling and ticketing data efficiently in one link, often over long distances.•The NetPrecis, operating in the 1400 MHz band, was deployed in a monitored hot standby configuration, reliably supporting PT Kereta Api real time communications to improve the safety and service provided to the company’s 200 million customers every year.

72

GSM network extension for OPT in French Polynesia

•The French Polynesian national communications provider, OPT, needed to extend GSM and POTS coverage to the remote island of Maiao, overcoming the problems of low subscriber densities, over-water distance and challenging environmental conditions.•The NetPrecis was used in the 1400 MHz band to provide a link from Tahiti to Maiao. Netronics is now the preferred supplier for such links and the network is being further extended.

73

Offshore connectivity for British Gas in Tunisia

•British Gas needed to continually monitor gas production parameters at the Miskar gas field, 125 km offshore. •Overcoming the problems of long distance, over water links, and constantly moving platforms, the NetPrecis was deployed in a three-hop link from the Miskar gas field to an onshore terminal, replacing the outdatedlow capacity analogue link. •Voice, data and video traffic is aggregated and transported over a 256 kbit/s link. The NetPrecis network has proved robust and efficient, enabling British Gas to closely monitor and manage production.

The NetPrecis has been distance-engineered for demanding applications, and makes the link where other products cannot. It outperforms each of these competing technologies in different ways.

76

VSAT

•Compared to VSAT, the NetPrecis: • Delivers much greater capacity• Requires lower operational expenditure• Enables customers to be in control of their own network infrastructure,

eliminating dependence on third party operators• Is able to overcome the problem of adverse weather conditions and sun

outages• Eliminates the problems of asymmetric connection (web server, file

transfer, VPN)• Has lower latency

The NetPrecis has a rapid return on investment, which can be as little as six months, varying per country depending upon the costs of VSAT services.

77

Higher frequency microwave

•Compared to higher frequency microwave (6 to 38GHz) the NetPrecis: • Can make longer distance links, eliminating or bypassing a network of

repeaters and requiring less infrastructure• Is better able to overcome the problems of adverse weather conditions,

because of its use of lower frequency bands (e.g. rain fade, harmattan) • Greatly reduces operational costs compared to a higher frequency network,

with reduced site rental costs

In one example Netronics replaced a network of three 13GHz point-to-point links with a single NetPrecis link in the 1400 MHz band generating a saving of over 60%.

The NetPrecis makes a compelling business case, with rapid return on investment.

78

Leased lines

•Compared to leased lines, whether E1 / T1 or greater capacity, the NetPrecis:

• Virtually eliminates operational expenditure

• Removes the dependence on the incumbent operator

• Is rapidly deployable and can be redeployed as needed

The NetPrecis puts the user back in charge of the communications network and its infrastructure, and results in a rapid return on investment.
