Engineering indoor wireless communication systems with high capacity

The effect of wall attenuation on the uplink performance of an interference limited indoor wireless communication system is investigated. An indoor environment containing multiple co-channel access points is investigated for connections made on the basis of strongest signal or best SIR and for varying intervening wall attenuations. Power balancing is used to equalize signal-to-interference ratios (SIRs), and performance assessed by the reuse probability which quantifies the probability that two or more mobiles at randomly chosen locations can successfully share the channel. Results obtained show that even moderate wall attenuations (10-15 dB) can produce practically useful performance gains.
