US Patent:

62821873, Aug 28, 2001

Filed:

Feb 1, 1996

Appl. No.:

8/595138

Inventors:

Allan Evans - Sunnyvale CA
Charles VanBlaricom - Cupertino CA
April Hunter - Los Altos CA

Assignee:

Stanford Telecommunications, Inc. - Sunnyvale CA

International Classification:

H04B 7212
H04L 1228

US Classification:

370347

Abstract:

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. +-. 2 modulation symbols through timing control from the base station to the user.
