19 3 PLC for rural and remote access Current situation The access to telecommunications is an economic and social factor without any type of doubt The geographical isolation of the rural and remote areas is historically a brake for the economic development, for cultural interchange and, in general, for the access to any type of services With the advance of the telecommunication technologies, the lack of infrastructures in the rural and remote areas has increased the Digital gap. In the case of the use of broadband services is specially noted that this technology is focused in urban areas The low density of the rural areas, highly spreads and with long distances to cover in order to be connected to the telecommunication networks increase the transport infrastructure cost Due to this later point, to extend broadband networks to rural and remote areas, at the end to the 100% of the population, is not a business for Telecommunication Operators 18

20 3 PLC for rural and remote access Transport Technologies A key issue to develop broadband services in rural and remote areas is to build a transport network that optimize investment and able to offer quality of service Remote Area Fiber Optic Fiber Optic PoP High capacity High cost, could be optimised if Power Line cables are used to support the Fiber Optic cable Remote Area Satellite Point of Interconnection with TELCOS Network Satellite PoP Remote Area Minimum infrastructure Difficult to provide voice service with standard quality Moderate cost Radio links Radio link PoP It is necessary a lot of intermediate antennas High cost, it needs manage permissions for frequencies and antennas, environmental impact 19

21 3 PLC for rural and remote access Fiber Optic in Power Lines Electricity arrive to rural and remote areas using Medium Voltage Power Lines. Fiber Optic manufacturers (Alcatel, Pirelli...) have develop different technologies to install Fiber Optic cables in the Power Lines OPGW Optical Ground Wire. The substitution of an existing ground cable by a cable combining the classical functions of a earth wire and telecommunications capacity has a long history OPPC Optical Phase Conductor. When the power line is not equipped with a ground wire is possible the substitution of the phase conductor MASS Metallic Aerial Self-Supporting. When is not possible to use ground or phase conductors a new cable can be added to the line ADSS All-Dielectric Self-Supporting Cables. Same case but without any metallic messenger wire ADL All-Dielectric Lashed Cables. Requires to use a ground or phase conductor as messenger wire. Is the fast and most cost-effective technology 20

22 3 PLC for rural and remote access Access Network Regardless transport technology used to connect remote areas, PLC technology can be interconnected with any other access technology in order to minimise CAPEX of the access network Access Network Architecture Comments PLC In-Home The most easy way to connect PLC equipment to other access technology is across layer two IP interfaces in which should be possible to define QoS using IEEE 802.1Q/p standards PLC PLC In-Home Wireless technologies such Wi-Fi and WiMAX in a near future could be easily combined inside a PLC network PLC PLC PLC technology can provide the connection for the different access points in order to minimize cost, to avoid problems of LoS and increase speed of roll-out PoP Inside houses or buildings can be used to minimize number of antennas 21

24 4 Conclusions As Access Technology Technology Trials have confirmed the viability of a PLC network and Commercial Launches are creating momentum among key telecom players (regulators, potential clients, operators and authorities) Conclusions Technology is able to support massive deployments: - PLC can offer Broadband Internet Access (> 2 Mbps) and VoIP services - PLC can be applied to low and medium voltage grids - Fast and selective deployment - Interconnection with public Internet and Telephone networks has proven viable - Competitive provisioning times - The market opportunity is evolving very fast Current regulation framework allows PLC Deployments Future generations of PLC Technology and price reductions (not only in PLC equipment) are key for competitive massive deployments Easy combination with other technologies in order to minimize the CAPEX of the access network 23

25 4 Conclusions As Business in rural areas Technology has been confirmed and is commercially available, but in order to be successful in the rural market it is needed the financial support of governments, mainly for the transport network Conclusions To roll-out a network to provide broadband services to rural and remote areas requires an high investment because is needed to arrive to low density populations over great distances Average nationwide (Spain) loop cost is about 250 Euros, but this figure doubles and even triples in high-cost rural areas It is necessary to offer to rural customers similar services and prices that to urban customers Competition as a solution in rural areas remains questionable With these conditions there is no business for private initiatives. Never will recover the investment Government has to reaffirm its commitment to provide universal service support through special help programs 24
