US Patent 7386309 Method and system for distributed wireless access

A method and system is provided for distributed wireless access. The system includes an access concentrator and a plurality of antenna modules. The antenna modules are spread across a campus and are coupled to the access concentrator via network wiring. Each antenna module includes an antenna to receive and transmit signals. When incoming signals are received at the antenna, the signals are converted from a radio frequency to a lower frequency. The converted signals are then digitized. The digital signals are then processed by digital signal processing resources at the access concentrator. Then, the processed signals are forwarded out of the corresponding ports to a LAN switch.
