Precis Examining and testing all aspects of the assembly and performance is apparent in the Net. Precis unbeatable reliability. For us, a high level of reliability is not an added bonus: it is mandatory. 32

More about the Net. Precis benefits The value of next generation sub 3 GHz technology

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 34

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 a 40 km path at 10 GHz, there is 100 d. B of rain fade, 30 d. B at 7 GHz, and 0. 5 d. B at 2 GHz. • At 7 GHz the link is lost, at 2 GHz there is still 5 x 9’s availability! 35

Harmattan and Khamsin • Dust and 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 d. B). At 1. 4 GHz there is less than 3 d. B fade for the same path, so it can be ignored. 36

Obstructed paths: the Net. Precis advantage • Typically point-to-point linking requires obstruction-free paths: this is not the case with the Net. Precis. 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

Obstructed paths: the Net. Precis advantage • The Net. Precis 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 d. B obstruction – others will recommend 0 d. B. 38

Challenging link to offshore floating platform ONSHORE SITE FLOATING TANKER 2 GHz co-linear whip omni antennae Tanker can rotate 360 degrees about fixed mooring 7. 2 km 39 • 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 Net. Precis 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: 40 • 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 3 GHz 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. FS FST T FA FAT T 41 Expensive tower structures MT MT Vs.

Precis 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 53

Hitless 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. 54

Hitless space diversity (HSD) 55

Monitored hot standby (MHSB) protection • The Net. Precis 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. 56

Monitored 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. 57

Expanding interfaces • The Net. Precis expansion shelf aggregates up to seven analogue and digital interfaces onto E 1 bearers for interface expansion. It comprises a standard Net. Precis chassis, a standard motherboard and power supply unit (± 12 VDC, ± 24 VDC, ± 48 VDC and AC) with a QJET interface card supporting fractional E 1/T 1. Configuration is easy: 58 • Add an Net.

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 Net. Precis in the 600 MHz band, with its Ethernet and E 1 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. 68

VSAT replacement in mobile market • Before the deployment of the Net. Precis in Indonesia, the operational expenditure of satellite as a backhaul solution was exceeding US$31 K per month for a 4 E 1 capacity. • With Net. Precis used as a terrestrial alternative, operational expenditure was eliminated and the link had a return on investment of less than six months. 69

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 75 km, to generate new revenue streams. • Using Net. Precis 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 Vo. IP, VLAN, VPN, video conferencing, PABX, POS and web hosting. 70

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 Net. Precis, 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. 71

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 Net. Precis 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. 72

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 Net. Precis 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 Net. Precis network has proved robust and efficient, enabling British Gas to closely monitor and manage production. 73

Relationship to competing technologies How Netronics and the Net. Precis outperform the rest

What technologies does the Net. Precis compete with? • The Net. Precis platform is typically used instead of, or to replace, one of the following: • VSAT • Leased lines • Higher frequency microwave The Net. Precis 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. 75

VSAT • Compared to VSAT, the Net. Precis: • 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 Net. Precis has a rapid return on investment, which can be as little as six months, varying per country depending upon the costs of VSAT services. 76

Higher frequency microwave • Compared to higher frequency microwave (6 to 38 GHz) the Net. Precis: • 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 13 GHz point-to-point links with a single Net. Precis link in the 1400 MHz band generating a saving of over 60%. The Net. Precis makes a compelling business case, with rapid return on investment. 77

Leased lines • Compared to leased lines, whether E 1 / T 1 or greater capacity, the Net. Precis: • Virtually eliminates operational expenditure • Removes the dependence on the incumbent operator • Is rapidly deployable and can be redeployed as needed The Net. Precis puts the user back in charge of the communications network and its infrastructure, and results in a rapid return on investment. 78

In conclusion What else can we tell you?
