Feasible connectivity solutions of PLC for rural and remote areas

Power line communication (PLC) is considered an attractive broadband delivery system because it can reach more homes than coaxial cable systems or telephone lines. In markets not served by DSL or cable, PLC can provides a cost-effective connectivity solution. Also known as "third wire" technology, PLC offer applications to rural and remote area in attractive modes like: i) high speed backbone over medium voltage power lines; ii) last mile access network through residential power distribution; Hi) last inch access to distribute data communication inside home. Considering the fact that network deployment costs can be reduced if signals are transmitted in an existing infrastructure, current status of PLC must be evaluated as an option to ICT efforts in rural and remote areas. This research targets to study the available technical benefits of PLC to rural applications as a backhaul, last mile or hybrid solution. Integration with current alternative technologies such as wireless and satellite communications can define an optimal solution according to individual community needs. Recommendations focused on municipalities or cooperatives are also discussed. Results indicate that PLC does not appear to represent a major disruptive technology in competitive markets, but very suitable for non supplied rural areas and should be considered strategically and technically for future policy decisions.
