The abundant spectrum available at mmWave band can provide high capacity, high throughput, and low latency. In this thesis, we present experimental measurements for 73 and 81 GHz mmWave bands. Wideband propagation measurements were performed at the Boise Airport concourse C area and tarmac for both line-of-sight (LOS) and non-line-of sight (NLOS) scenarios. Power delay profiles were recorded and analyzed with close-in free space reference path loss models and floating intercept path loss models. In addition, building material attenuation at 28, 73, and 91 GHz is presented. Measurements at 73 GHz for wideband and narrowband signal are performed with directional antennas. Moreover, wideband spatial fading measurements were performed at the Boise State University Micron Engineering Building and Boise Airport. The power delay profiles are recorded and analyzed with Rayleigh, Ricean, and log-normal models. Large scale path loss parameters at the airport, material attenuation and small scale fading parameters were computed. The results can help researchers and network designers in simulation and design of mmWave wireless networks.
