Millimeter-wave 60 GHz Outdoor and Vehicle AOA Propagation Measurements Using a Broadband Channel Sounder
Millimeter wave (mm-wave) channel models for outdoor wireless systems with adaptive antennas are needed to exploit the massive bandwidths available at frequencies above 30 GHz. In this paper, the authors describe 60 GHz wideband propagation measurements in cellular Peer-To-Peer outdoor environments and in-vehicle scenarios. They present a channel sounder that operates at 38 and 60 GHz with a passband bandwidth of 1.9 GHz. The channel sounder provides sub-ns RMS delay spread measurement resolution and Angle-Of-Arrival (AOA) capabilities. AOA multipath measurements for cellular Peer-To-Peer communications in an outdoor campus setting show that in all measured locations, some Non-Line Of Sight (NLOS) antenna orientations can exploit beamforming to create links using scattering in the channel.
