Time-Average Behaviors of Indoor Propagation Channels on Wireless Applications

This paper investigates the three-dimensional spatial distribution of incident waves within an indoor environment over commonly used wireless bands such as GSM900, GSM1800, IMT2000 and WiFi 2.4 GHz. Unlike previous works, the proposed approach derives the time-average behavior of the channels from the received powers coming from common existing RF transmitters. It is seen that the 3D-spatial envelopes of the channels over wireless bands are Gaussian-type only for downlinks.
