Attenuation of 900 MHz and 1.35 GHz signal inside room of a building

The performance of indoor communication services offering the transfer of voice and data inside a building is severely affected by the presence of a large number of scatterers/reflectors. The paper reports the results of propagation measurements at 900 MHz and 1.35 GHz conducted inside a room on a floor of a office-cum-laboratory building. From the measured data, the path loss exponent, standard deviation, RMS time delay and coherence bandwidth are determined.
