A networking method for a wireless point base station to a plurality of users where the 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. Medium access is achieved by actively controlling assigning frame time slots in the upstream direction to accommodate varying demands for bandwidth by multiple users. The upstream frame time slots are synchronized to the downstream frame timing, the time slots carrying individual ATM cells, the first time slot of the downstream frame carries a frame start ATM cell. Upstream time slot synchronization is maintained to within &plusmn;2 modulation symbols through timing control from the base station to the user. Random access time slots are used for control plane requests by users entering the network and users in standby mode seeking to begin a session, polling is used for management plane functions and responses by users are on a polling response time slot.

System for the delivery of wireless broadband integrated services

A networking protocol for wireless point (base station) to multipoint (user) networks where the users are stationary which utilized time-division multiplexing the in the direction of the base station to the user, heretofore called the downstream direction, and time-division multiple access in the direction of the user to the base station, heretofore called the upstream direction, where medium access control actively assigns time slots in the upstream direction to accommodate varying demands for bandwidth by multiple users, where upstream frame timing is synchronized to the downstream frame timing, where time slots carry individual ATM cells, where the first time slot of the downstream frame carries a frame start ATM cell, where upstream time slot synchronization is maintained to within .+-.2 modulation symbols through timing control from the base station to the user, where random access time slots are used for control plane requests by users entering the network and users in standby mode seeking to begin a session, where polling is used for management plane functions and responses by users are on a polling response time slot.
