Frequency-Dependence of Channel Delay Spread in an Outdoor Environment

Abstract : 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 DS with regards to the frequency. This disagrees in some way with the 3GPP TR 38.900 channel model findings which support a clear decreasing trend of this parameter as the frequency increases. At 60 GHz, the channel DS was computed with and without compensation of atmospheric oxygen absorption. It was found that this phenomenon has minor impact on the measurement results. Its compensation does not change the main conclusions.
