A scaleable, broadband wireless system for providing radio access to a metropolitan area. The metropolitan area is sub-divided into overlapping cellular areas each having a base station for communication with network interface units at customer sites within each cell. ATM Radio Interface Cards (ARICs), both time division multiple access (TDMA) and frequency division multiple access (FDMA), in each base station implement protocols for bi-directionally linking the NIUs with the ATM backbone. FDMA ARICs provide point to point radio access between base stations over intercell links. The capacity of the system can be scaled by adding the appropriate ARICs as required to meet demand.

Cellular base station with integrated multipoint radio access and intercell linking

A system and method for the transmission of synchronization information from a wireless asynchronous transfer mode (ATM) base station across a point to point or point to multipoint wireless link, to one or more network interface units (NIUs). Each of the NIUs is capable of supporting a combination of structured or unstructured T1 and/or E1 circuit emulation services. The technique involves locking the wireless modem downstream symbol clock to an externally provided frequency reference from the base station. The reference is an N integer multiple of 8 kHz which is the lowest common denominator for both the T1 and E1 clocking rates.
