Fixed Radio Systems - Point-to-multipoint equipment - Time Division Multiple Access (TDMA) - Point-to-multipoint digital radio systems in frequency bands in the range 3 GHz to 11 GHz
The present document covers equipment, which may operate in frequency bands that have paired frequencies, which
can be used by either equipment employing Frequency Division Duplex (FDD) or Time Division Duplex (TDD)
techniques. For use with Time Division Duplex only one frequency of the frequency pair will be used and for the
purpose of the present document the tx/rx separation will be zero. The channel spacing is intended to be the same in
downlink and uplink directions.
This revision extends the scope to cover systems employing basically TDMA multi-access but which also allows for
additional methods (such as OFDMA) combined with TDMA, to be used to provide another dimension of multiple
access.
