Propagation inside buildings suffer from large shadowing and high multipath effects. This is a serious problem for Wireless Local Area Network (WLAN) systems. OFDM has a high multipath tolerance and this paper shows how this can be used to overcome the problems due to shadowing. OFDM allows a base station to transmit and receive the same signal at the same frequency from multiple locations, at a low cost and without the detrimental effects of Inter-Symbol Interference (ISI). The reduced shadowing and path loss allows: an increased system capacity for such a multi-transceiver WLAN cell, or a decrease in intercellular interference in a cellular WLAN
