Interference Analysis of an in-Building Wireless Communication System Employing Vertical Frequency Reuse

The reception quality of an interference limited indoor wireless communication system employing vertical frequency reuse is analysed. Outage probability expressions are used to measure the level of cochannel interference. The received signals are assumed to suffer the effects of Rayleigh fading and log-normal shadowing and multiple cochannel interferers are included in the analysis. The expected reception qualities are studied in a range of buildings and the results show that typically a vertical reuse distance of 3 floors will not isolate cochannel floors sufficiently to allow reliable reception. For one building analysed, even a vertical reuse distance of five floors is not likely to result in sufficiently low levels of cochannel interference. When multiple interferers are considered, it is not a straight forward task to determine the number of cochannel interferers that contribute significant interference since this may depend on the propagation conditions in a particular building.
