ABSTRACT:
Data is wirelessly transmitted from a base station, and/or wirelessly received at a plurality of subscriber stations that are at a plurality of distances from the base station using a Time Division Multiple Access (TDMA) frame by transmitting a same amount of data to each of the subscriber stations at a same power level during the TDMA frame while varying at least one other parameter as a function of the distance of the respective subscriber station from the base station. The at least one other parameter may be an amount of error correction coding, a sub-period duration in the TDMA frame, a number of modulation symbols from a set of modulation symbols and/or a number of sub-periods of the TDMA frame.
