This paper presents the empirical measurements of 15 GHz outdoor channel propagation at a university campus for 5G communication system. Measurements are performed at the university campus using one receiver location and 100 transmitter locations placed in concentric circles within a 200-m radius. A 400 megachip-per-second channel measurement system, directional horn antenna, and omnidirectional antenna are used to measure propagation characteristic for the 15 GHz spectrum. This paper presents measurement results for the path loss of the transmitter-receiver separation distance, the different azimuthal angles corresponding to the received power, and the power delay spread for concentric circles of different radii and overall transmitter locations in the campus. The statistical data demonstrate that the 15 GHz spectrum is available for use as the next generation of radio communication.
