Wireless over Cable (WoC) paradigm is a new technique to enable distributed antennas systems. WoC is based on the relay of radio frequency wireless signals over a cable infrastructure through a bidirectional (analog) amplify and forward device that translates the bandwidth of wireless signals to comply with the specifications of the wired links. Following the WoC concept, here xDSL connection in femtocell architecture is replaced with a plain connection of the antenna with telephone lines after up/down-frequency conversion to enable Radio over Telephone Lines. Baseband processing and radio resource management is carried out simultaneously for multiple femtocells thus centralizing scheduling and mitigation of radio frequency interference among neighboring femtocells.
