Experimental Studies of the 2.4-GHz IMS Wireless Indoor Channel

Abstract

Experimental results from indoor measurements of the 2.4-GHz wireless channel are presented. These measurements include both quasi-static and time-varying channel conditions in a number of indoor environments. Four channel propagation characteristics of interest are evaluated. For the time-varying environment, the Doppler spread of the wireless channel is measured. For the quasi-static environment, mean excess delay, rms delay spread, and coherence bandwidth of the channel are determined. The effect each of these propagation characteristics has on multiple antenna wireless systems and their suitability for indoor use is discussed.
