Abstract

A data collection in the 2.4GHz ISM band was performed in order to characterize the coupling between a colocated transmitter and receiver in a time-varying, frequency-selective, wideband outdoor channel. Once least-squares channel estimates are obtained, channel length, RMS delay spread, coherence time, and coherence bandwidth are calculated. The values help assess the effects of line-of-sight (LOS) versus non-line-of-sight (NLOS) and traffic conditions, and are being used to inform the design of an advanced adaptive communications system.
