Abstract

The local loop can be of two kinds, the local loop with copper wires and the local loop that use radio technology. Under certain conditions, the wireless Local Loop (WLL) can be an alternative more interesting than the copper local loop. We study in this paper the behavior of a radio channel and the multipath effect in a WLL transmission.

Key words: Wireless Local Loop (WLL), radio channel propagation, multipath, channel modeling, time excess delay, coherence bandwidth, frequency selective, frequency non selective fading channels.
