Common use of Physical layer Clause in Contracts

Physical layer. The physical layer of the Internet FWA air interface uses digital time division multiplex/time division multiple access (TDM/TDMA) with a 10-slot frame structure. Uplink and downlink carriers are paired, and separated by a fixed duplex spacing of 99.84MHz. A TDM/TDMA channel (i.e. one time-slot one on one RF carrier) is known as a physical channel. In the maximum configuration, one ITS provides 18 pairs of RF carriers, and 180 physical channels. The uplink carriers are contained within the frequency band 3425 MHz to 3450 MHz, and the downlink carriers are contained within the frequency band 3525 MHz to 3550 MHz. The modulation scheme for both the uplink and downlink direction is pi/4 shifted differential quadrature phase shift keying ((pi)/4DQPSK) with a nominal symbol rate of [ * ] symbols/s. The gross data rate is [ * ] kbits/s per carrier.

These access channels are not available for carrying subscribers’ voice or data traffic.
