30How reliable is NetPrecis? Very! Netronics has unrivalled reliability:Industry standard failure rates typically exceed 4-5% per annumNetPrecis average is less than 1.2% per annumNetPrecis 2008 average failure rate was 0.76%With zero out-of-box failures in 2008Despite less than optimal conditions:Mud hutsSand and dust stormsWithout air conditioningNeteronics has one repair technician who uses less than 25% of his time for the global NetPrecis install base30
31NetPrecis reliability: superior performance comes as standard The NetPrecis reliability cannot be beaten.0.76% failure rate, compared to 4-5% industry normZero out-of-the-box failures in 2008With an installed base approaching 10,000 unitsMTBF, based on returns to factory, is yearsThis 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.31
32More 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 CelsiusPerformance data is automatically monitored and recorded throughout, and analysed at test completionWhy 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 performanceTemperature changes are one of the most common causes of early life failures in the field: this has been eliminated for NetPrecisExamining 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.32
33More about the NetPrecis benefits The value of next generation sub 3GHz technology
34Sub-3 GHz advantagesOperating 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 gainLess absorption by obstructions or weather eventsEnvironmental effects:Near non line-of-sight or shaded paths: with carrier-class resultsFades from rain or Harmattan are negligible, and ducting is considerably reducedReduced infrastructure and maintenance:All indoor mounting means reduced maintenanceConsiderably lighter antenna systems, with reduced tower loading and rigidity: a wooden pole may be sufficient34
35Precipitation: 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 a 40 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!35
36Harmattan and KhamsinDust and sand storms result in a haze-like effect, catastrophic for higher frequency microwave:Fades double during HarmattanEach fade is two to three times the depthSignificantly reduces availability and possible path distancesCauses temperature inversion and duct entrapment for higher frequenciesThis 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.36
37Obstructed 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.37
38Obstructed 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 componentryUse of advanced signal correction: multi tap adaptive equalisation to remove phase distortions and the affects of diffractionForward error correction: to resolve any resulting errorsNetronics engineers can design the optimum solution for the application, allowing in excess of 20 dB obstruction – others will recommend 0 dB.38
39Challenging 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 YemenThe challenge:Over-water link, with associated problems of multipath and signal fading360 degree rotation of the 350 metre long FSO about a fixed mooring facilityConstant pitch, roll and height variations with tides, currents and weatherTidal changes and FSO loading variations causing changes to relative height of antennas above sea levelONSHORE SITEFLOATING TANKER2GHz co-linear whip omni antennaeTanker can rotate 360 degrees about fixed mooring7.2km39
40Challenging link to offshore floating platform Conventional solution:Antenna tracking system with high gain narrow beamwidth antennasExpensive and unreliable due to corrosion of moving parts: regaining lost signal takes time and reduces link availabilityNetPrecis hitless space diversity solution:Two omni-directional antennas at separate sites on FSO, made possible by use of low frequency 2 GHz bandTwo directional parabolic grid antennas at onshore site, with wide beamwidth to cover 900 metre movement of FSO tankerThe result:24 Mbit/s Ethernet capacity deliveredConstant link with no traffic errors, despite pitch, roll and height movement of FSO40
41Reduce 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 mastsWith minimal support needed, site acquisition can be much simpler and quickerWhy? Because grid type and Yagi antennas weigh much less than solid parabolic antennas and are significantly less affected by wind force.Expensive tower structuresFS TFA TM TFSTFATMTVs. Minimal infrastructure
42Comparing grid type and solid parabolic antennas Using a grid type rather than a solid parabolic antenna means that:Frontal loading (FAT) is reduced by 75%Horizontal loading (FST) is reduced by 60%Turning force (MT) is reduced by 85%Average figures calculated from multiple manufacturers. 200 km/hour wind speed42
43Comparing Yagi and solid parabolic antennas Using a Yagi antenna rather than a solid parabolic antenna means that:Weight is minimal: a 1.6 metre Yagi antenna weighs only 1 kgHorizontal loading and turning force are greatly reducedAntenna sizeWeight (kg)FST max (N)MT max (Nm)0.3m (1 ft)0.21110.6m (2 ft)0.52750.9m (3 ft)0.743151.4m (4.6 ft)0.970401.6m (5.25 ft)1.075532.4m (8 ft)1.35108116FSTMTAverage figures calculated from multiple manufacturers. 160 km/hour wind speed43

51Performance information Summary information or a detailed constellation diagram are available, with SuperVisor providing easy to understand performance statistics.31 March 2017
52SNMP-based network management Industry-standard SNMP management software enables network-wide management.Netronics uses Castle Rock’s SNMPc, which can remotely access many NetPrecis terminals in a network from one location via an IP network.
53Hitless space diversity (HSD) The NetPrecis HSD option is implemented as a space diversity solution with two boxes, for hitless path protection, protecting against signal fades and increasing the overall path availability. The link survives failure in a transmitter or receiver. HSD provides a limited degree of equipment protection, and does not provide interface redundancy
54Hitless space diversity (HSD) Two boxes, a main and a standby protected radio are connected via a protection interface card and protection switch card and managed together as one terminal. One box is transmit and receive, the other receive only, with the default active transmitter in the upper chassis. Switching is hitless receive.
56Monitored hot standby (MHSB) protection The NetPrecis MHSB option provides complete equipment redundancy for mission-critical communications or where there is limited site access.MHSB comprises a two radio solution for complete peace of mind.
57Monitored hot standby (MHSB) protection MHSB protection comprises CPU-controlled switching with constant alarm monitoring. Transmitted power is switched between the antenna and an RF dummy load. Both Radio A and Radio B can be managed via the Ethernet interface.
58Expanding interfacesThe NetPrecis expansion shelf aggregates up to seven analogue and digital interfaces onto E1 bearers for interface expansion. It comprises a standard NetPrecis chassis, a standard motherboard and power supply unit (±12 VDC, ±24 VDC, ±48 VDC and AC) with a QJET interface card supporting fractional E1/T1. Configuration is easy:Add an NetPrecis shelf to the standard NetPrecisAdd the required interface cardsDrag and drop analogue and digital interfaces onto fractional E1/T1 with cross-connectInterconnect E1 ports and Ethernet for management
59Expanding interfacesEach Expansion shelf supports up to seven interface cards, with a fractional E1/T1 uplink. The customised SuperVisor software has the same look and feel as the standard NetPrecis software.
60Expanding interfacesIf more ports are needed, more Expansion shelves can be added.

63Infrastructure 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.
64Fully 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.64
65Fully 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.
66Rural 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, plus2-wire voice, including payphone signalling, plusE1, Ethernet, RS-232, 4-wire voiceThe NetPrecis enabled Sri Lanka Telecom to increase the range of services available, increase revenue opportunities and acquire new customers.
67Backhaul 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.
68Remote 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.
69VSAT 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.
70Remote 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.
71Private 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.
72GSM 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.
73Offshore 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 outdated low 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.
74Relationship to competing technologies How Netronics and the NetPrecis outperform the rest
75What technologies does the NetPrecis compete with? The NetPrecis platform is typically used instead of, or to replace, one of the following:VSATLeased linesHigher frequency microwaveThe 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.
76VSAT Compared to VSAT, the NetPrecis: Delivers much greater capacity Requires lower operational expenditureEnables customers to be in control of their own network infrastructure, eliminating dependence on third party operatorsIs able to overcome the problem of adverse weather conditions and sun outagesEliminates the problems of asymmetric connection (web server, file transfer, VPN)Has lower latencyThe 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.
77Higher 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 infrastructureIs 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 costsIn 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.
78Leased linesCompared to leased lines, whether E1 / T1 or greater capacity, the NetPrecis:Virtually eliminates operational expenditureRemoves the dependence on the incumbent operatorIs rapidly deployable and can be redeployed as neededThe NetPrecis puts the user back in charge of the communications network and its infrastructure, and results in a rapid return on investment.
