In fact In-home PLC networking is a well established technology with devices commercially available from a number of manufacturers. As far as the cabled lines, the PLC technology is used to bridge the “last mile” between the broadband core (fiber optic) network and the home or office and also within the home (similar to the function of a local area network). In addition PLC is a direct competitor to DSL technology and uses similar modulation techniques. Both technologies exploit existing copper wire networks. The use of existing cabling greatly reduces installation costs as it avoids the need for putting in extra cabling. The commercial PLC offerings are competitive and cheaper than DSL and can extend broadband reach to areas where DSL and cable are not available. To enhance the fixed network by building new local loop infrastructures requires substantial investment. As a result, the barriers to broadband deployment using DSL technology may be high. With PLC technology the user employs home networking devices such as Ethernet-to-PLC or USB-to-PLC USB (universal serial bus) for interconnecting several computers, sharing printers, or DSL or cable modem connections. Low voltage PLC networks can provide access to open networks such as the Internet. With this approach, users gain access through a head-end modem installed in an MV-to-LV transformer providing connections to all subscribers in a neighborhood. The high end modem has a medium voltage link to a high speed core network. Cost reduction is achieved

Although multiple technical and regulatory problems still exist with PLC as an access technology, it can be evaluated as an alternative access technology in regional telecommunications as the ubiquity of power lines is unmatched by either cable or phone networks. The electricity grid reaches almost 100% of the population, so power line communications, based on existing infrastructure currently providing electrical power, has the potential to offer omnipresent broadband service reasonably quickly and at reasonable cost.
