Abstract :
Small-scale fading and propagation delay have been characterized for the 2.4 GHz band in a specific conference room with 802.11 coverage problems and a more typical conference room for comparison. The measurements were executed with a virtual SIMO (Single-Input Multiple-Output) system. The implications on the 802.11 performance have been investigated in terms of received signal strength and intersymbol interference. A higher reverberation time was found in the room with coverage problems, which causes a higher chance of intersymbol interference.
