Angular Resolved Pathloss Measurements in a US Suburban Scenario at 28 GHz

This paper presents angular resolved path loss measurements conducted along the streets in a typical US suburban scenario at 28 GHz. It was observed that all Rx location up to 150 meters from the Tx had a detectable signal with path loss under 145 dB and all Rx location up to 200 meters had a detectable signal with path loss under 155 dB. It was also concluded that the LOS direction was the clearly dominating peak power direction even for locations with more than 30 dB excess loss. The angular spread was unexpectedly low, below 10 degrees for half of the locations, which indicate only one or very few closely spaced dominating paths. Finally, the impact of the AP height on the coverage was investigated and for this scenario very little improvements could be noticed increasing the access point height from 6 to 9 or 15 meters. This is likely due to the height of the trees often exceeding 15 m in the measured scenario.
