<p>A networking protocol for wireless point (base station) to multipoint (user) networks where the users are stationary, which utilizes time division multiplexing in the direction of base station to user; i.e. the downstream direction; and time division multiple access in the direction from the user to the base station; i.e. the upstream direction. Time slots in the upstream and downstream directions carry ATM cells. Users maintain time slot synchronization to within 2 modulation symbols by monitoring downstream receptions (11) and central processing unit (7) tracks time slot assignments and handles in-band signaling while segmentation and reassembly (6) handles treatment of the ATM cells.</p> |
