Abstract

See full text

A method and system for the reception, conversion and distribution of wireless communication signals received from such communication devices as PCS, Cellular, and Satellite over AC power lines commonly found within a building, office, home or other structure is disclosed. This invention specifically provides for the distribution of wireless signals in structures where otherwise signal degradation and/or blockage are common. Moreover, this invention takes advantage of the existing AC power lines to create a communication channel avoiding the necessity of rewiring the building or other structure. This invention provides important improvements to the signal coverage and reception of wireless transmitted signals within buildings and other structures and does so in an efficient and cost effective manner.
