ABSTRACT:
A communication channel is controlled so as to dynamically accommodate network client requests for access thereto. The communication channel may be supported on a wireless link, such as a spread spectrum wireless link, and client requests for access thereto may be dynamically accommodated by allocating time slots for client transmissions on the wireless link. Providing a quiet time slot within which clients may request access to the communication channel may accommodate various client requests for access to the communication channel. These quiet slots may exist with other forward and reverse time slots which are superimposed on the communication channel, each forward and reverse time slot including one or more data frames. The forward and reverse time slots are preferably fixed, but negotiable, time periods. Each of the data frames may include a plurality of data packets, each of the data packets being variable in length. Preferably, each of the data packets includes error correction coding information as well as information which may be used to synchronize pseudo-random number generators of a transmitter and a receiver operating according to the communication protocol. Each of the data frames may further include link identification information that uniquely identifies a wireless link supporting the communication protocol.
