Abstract:

A multiple distributed antenna access point (MDA/AP) system which compensates for wireless path loss and increases data throughput between AP and mobile user stations includes a central unit including one or more central antennas, a distributed antenna unit including multiple distributed antennas and an auxiliary unit interfacing the central unit with the distributed antenna unit, with each unit being separate or the central and auxiliary units being integrated. The central unit functions as a traditional access point and is operable in time division duplex (TDD) or frequency division duplex (FDD) mode. One or more central or distributed antennas are utilized to transmit and receive signals to and from the mobile user stations where selection of the antenna(s) used for a given mobile user station determines the throughput of the transmission. A method for selecting an antenna for optimal performance of the MDA/AP system using a CSMA/CA distributed coordination function (DCF) communications protocol includes employing one or more control antennas of the MDA/AP system during an RTS or CTS period and selecting one or more antennas during a data period.
