Abstract

The reception quality of an interference limitedindoor wireless communication system employingvertical frequency reuse is analysed. Outageprobability expressions are used to measure the levelof cochannel interference. The received signals areassumed to suffer the effects of Rayleigh fading andlog-normal shadowing and multiple cochannelinterferers are included in the analysis.The expected reception qualities are studied in arange of buildings and the results show that typicallya vertical reuse distance of 3 floors will not isolatecochannel floors sufficiently to allow reliablereception. For one building analysed, even a verticalreuse distance of five floors is not likely to resultin sufficiently low levels of cochannel interference.When multiple interferers are considered, it is not astraight forward task to determine the number ofcochannel interferers that contribute significantinterference since this may depend on the propagationconditions in a particular building.
