摘要：3GPP Rural Area channel model is used to measure the performance of different wireless systems i.e. UMTS, WLAN and WiMax. This paper showed that the channel impose a slow fading effect at = 5 Hz and fast fading at = 100 Hz these details shows how the user mobility affect the data reception. A further analysis shows that Rural Areas tends to be flat for wide band signals with a coherence bandwidth equals to the half of the transmitted bandwidth. For low mobility condition (= 5 Hz) the channel shows a significant change every 25 (ms) which is quite slow according to the delay requirements of wide band communications, however as the mobility increases (= 100 Hz) the channel tends to vary significantly in order of few milliseconds.
