Abstract :
Measurements of time delay spread of wideband 850 MHz digital radio signals due to multipath propagation within a large building are described. These measurements show a median RMS time delay spread of 125 ns and a worst case of 250 ns. Consequently, signalling rates above 400 kHz may not be feasible.
