Abstract :
In order to characterize the radio channel in typical WLAN scenarios a wideband measurement campaign at 5 GHz has been carried through. Four offices and two large open space environments have been investigated. Impulse response shape and fading statistics have been analyzed. Moreover, the Doppler characteristics have been studied. It was found that the impulse responses basically had the shape of one exponentially decaying cluster. The measured Doppler spectra indicates a basically uniform distribution of radiowave direction of arrival. Measured RMS delay spreads were in the range 10-100 ns
