Broadband over power lines (BPL) in Brazil : solutions for rural areas

Abstract

Broadband over power lines (BPL) 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, BPL can provide a cost-effective connectivity solution. Also known as ``third wire`` technology, BPL 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; iii) 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 BPL can be evaluated as an option to ICT provision in rural and remote areas. This research targets to study the critical factors for deployment of BPL technologies in rural areas served by to Cooperatives of Electrification in Brazil. It is presented a model of Task PEST Fit to analyze not just the Technology itself, but also Economical, Sociological and Political factors that may influence on decision making and service deployment. As a result, this study provides elements for future empirical analysis of telecom-electricity convergence in Brazil and provision of broadband services for underserved areas.
