Abstract
In an indoor environment, channel variations which occur most frequently are due to the movement of personnel near the transmitting or receiving antennas and/or local movements of the terminals around a given location. Such short-time variations in the indoor radio channel are studied and determined by performing propagation experiments in line-of-sight and non-line-of-sight environments at 910 MHz. The database is divided into two classes: global short-time and local short-time variations. Global short-time variations deal with the changes in the radio channel, observed over time and space, at different locations in an area. The local short-time variations address changes induced over time, by human traffic close to the fixed transmitter/receiver or by manually shaking the antenna on its base. The statistics of RMS delay spread and the received power in the multipath profiles are computed and compared for these experimental variations.Keywords
