Abstract
A wireless data network, including a base station and multiple mobile wireless terminals, implements a synchronous 2-way communication protocol in which the availability of a communication channel is signalled by the base station in a control packet. The multiple mobile wireless terminals compete for acquisition of the communication channel by sending a request packet, upon detecting from the control packet that the communication channel is available. The base station grants the channel by acknowledging the request packet of a selected one of the mobile wireless data terminal. The mobile wireless data terminal communicates with the base station over the communication channel subsequent to acquisition. Upon the wireless data terminal relinquishing the communication channel, the base station sends out the next control packet indicating that the communication channel is again available.
