ATSC 3.0 mobility reception was put to work in two field tests conducted by Sony in Phoenix, with Pearl TV Group, and Santa Barbara, Calif., with News-Press and Gazette. The tests, detailed in a recently released white paper, demonstrated the advantages of using ATSC 3.0 for mobile reception and providing software updates to future autonomous-powered vehicles. The field tests specifically looked at the demodulator chips from Sony Semiconductor and related software for ATSC 3.0 created by Sony Home Entertainment and Solutions of America. The testing areas-mountain passes and urban settings in Phoenix and a route along the Pacific coast near Santa Barbara-provided their own unique reception challenges. Among the tests' findings was that having a mix of active and passive reception antennas couLd be beneficial to accommodate all channel conditions of strong and weak signal strength.
