Abstract:
A networking method for wireless point base station to plurality of users where said users are stationary and which utilizes time-division multiplexing in the downstream direction of the base station to the user, including downstream frame timing, comprising:providing time-division multiple access in the upstream direction of the user to the base station,controlling medium access by actively assigning frame time slots in said upstream direction to accommodate varying demands for bandwidth by multiple users, said upstream frame time slots are synchronized to said downstream frame timing, said time slots carry individual ATM cells, the first time slot of the downstream frame carries a frame start ATM cell,maintaining said upstream time slot synchronization to within .+-.2 modulation symbols through timing control from the base station to the user,causing random access time slots to be used for control plane requests by users entering the network and users in standby mode seeking to begin a session, andcausing polling to be used for management plane functions and responses by users are on a polling response time slot.
