Propagation measurements at 5.2 GHz in commercial and domestic environments

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