Abstract:
1. A system for providing a streaming service in a wireless packet network comprising: a wireless router having an antenna and configured to: achieve a predetermined error rate for transmission of data packets by adapting a modulation and coding level, the adaptation of the modulation and coding level based at least on a relationship between the error rate and a signal-to-interference-plus-noise ratio, wherein the signal-to-interference-plus-noise ratio is determined at least by a signal path gain, a maximum transmission power level, and a predicted interference power level; and adjust a transmission power based at least on the adapted modulation and the coding level to a level which provides desirable performance, wherein the antenna is configured to transmit the packets of data in accordance with said modulation and said coding level and with said transmission power, and wherein the wireless router is configured to adjust the transmission power level based on a value of the signal-to-interference-plus-noise ratio multiplied by a value of the predicted interference power level divided by a value of the signal path gain.
