Radio frequency propagation measurements across wireless commercial bands (39 GHz, 28 GHz, Sub 6 GHz, Sub 3 GHz, and Sub 1 GHz) play a critical role when designing wireless networks. Understanding propagation characteristics allows more efficient  communication networks design, through base station placing for optimum coverage. Path loss and link quality measurements are both necessary to understand the system performance under different propagation environments. Through this project we propose to investigate the propagation characteristics at 1.9, 3.7, 28 and 39 GHz in different indoor and outdoor locations across campus, using Software Defined Radios (SDRs), signal generators and spectrum analyzers to measure the path loss and link quality.
