Temporal Variations of the Indoor Wireless Millimeter-Wave Channel

Page 928.

Abstract:

This paper reports experiments conducted near 30 GHz to characterize human-induced variations of an indoor radio channel for which both terminals are stationary. The dependence of envelope characteristics on various parameters (degree and localization of movement, terminal configuration, and spatial short-range fading level) is examined. In particular, it is found that the received envelopes may be considered realizations of only locally stationary processes, even when movement in the propagation environment is homogeneous. The results presented may be used in the design of broad-band wireless LAN's and serve as a basis for the development of a theoretical model capable of predicting channel temporal variation characteristics under a variety of conditions.
