Frequency-dependence of channel delay spread in an outdoor environment

Millimeter-Wave (mmW) communication systems, capable of achieving high data rates thanks to the large bandwidth available in this frequency range, are a promising 5G technology. Studies in this paper investigate the radio propagation channel at 3, 17 and 60 GHz in an Outdoor environment. Measurements were conducted using a wideband channel sounder to derive channel delay spread (DS). Results do not indicate a clear trend on the behavior of the...
