Abstract

See full text

A method for communicating information bidirectionally between a wired network (1) and a wireless network. The wireless network is of the type that includes header stations (12) each having a communication cell (2) associated therewith and one or more mobile communication units (10) disposed within the communication cell. The method includes a first step of, during a first portion of a wireless communication cycle, transmitting information over an uplink wireless communication channel from one or more of the mobile communication units to the header station. A second step of the method, accomplished during a second portion of the wireless communication cycle, transmits information over a downlink wireless communication channel from the header station to one or more of the mobile communication units. The information transmitted downlink includes frames of data received by the header station from the wired network. The first portion may be accomplished in part or in total by a CSMA protocol where the mobile units contend for access to the uplink communication channel. In one embodiment the header station initiates the first portion by transmitting to the header stations information for scheduling the sequence of the uplink transmissions.
