When both the base station and subscriber antennas are located in the cluttered multipath environment inside buildings, fast fading is observed as either antenna is moved over a distance on the order of a wavelength. The fast fading is evident in measurements made on CW signals, on individual arrivals for pulsed excitation, even for pulses as short as 5 ns. The statistical properties of the fading are discussed, along with the usual measures of the pulse response, such as path loss, mean excess delay, rms delay spread and coherence bandwidth.
