Abstract: This paper presents the results of an investigation into the wideband propagation characteristics of four different indoor operational environments in the vicinity of 5.2 GHz frequency band using a swept time- delay cross-correlator (STDCC) channel sounder with a bandwidth of 200 MHz. For each environment the cumulative distribution of delay spread for both omni directional and a 20 dB horn antenna have been presented. It has been shown that the suitably aligned narrowbeam antenna makes possible to achieve delay spread reduction through spatial filtering. The effects of moving people and different room transmission situations has also been presented.
