The Wideband Characteristics of 28/38 GHz in Urban Low-rise Environments

The millimeter wave bands will be used for 5G or IoT to overcome frequency insufficiency. This paper shows relations of received power, multipath delay spread and distance in urban low-rise environments at both 28 and 38 GHz. The wideband characteristics had been measured with a channel sounder, a directional antenna for transmitter, and an omni-directional antenna for receiver in Daejeon area.
