Wireless propagation measurements in indoor multipath environments at 1.7 GHz and 60 GHz for small cell systems

Given the current interest being shown in the utilization of the frequency band around 1.7/1.8 GHz and 60 GHz, work has been undertaken to determine channel characteristics in these two ranges. The authors describe wideband measurements which have been conducted in a variety of indoor locations. RMS (root mean square) delay spreads were calculated and used to compare levels of multipath activity at the two frequencies. The levels of multipath measured at the two frequencies can be related to the size of the rooms involved and the measurement techniques. Any differences due to atmospheric absorption at 60 GHz were found to be negligible.<
