摘要

Path loss exponent represents how fast the path loss increases with distance and it accounts for signal indoor outages. These indoor outages can arise due to signal building penetration loss. Signal penetration loss depend on the type of building material used. This research investigated the effect of building on the GSM signals of MTN, Glo, Airtel and Etisalal using radio frequency signal tracker to conduct measurements on five (5) different buildings (mud house with thatched roof, mud house/rusted corrugated iron sheet roof, sandcrete building/rusted corrugated iron sheet roof, sandcrete building/unmsted corrugated iron sheet roof and building with alucoboard wall cladding) in Rivers State, Nigeria. The results obtained were compared to the Okumura, HATA and COST-231 models and it showed that building with alucoboard wall cladding has the highest signal loss while the sandcrete building/unmsted corrugated iron sheet roof has the lowest signal loss, with all measurements values corresponding to the Okumura model. For each of the network and environment considered, the path loss exponent varied between 3.06 to 4.59 and the standard deviation between 11.1dB to 11.6dB.
