The present document applies to radio equipment at the Ground Station and Aircraft Station for Broadband Direct Air-to-Ground communications systems employing beamforming antennas. These radio equipment types are capable of operating in all or any part of the frequency bands given in table 1. Table 1: Radiocommunications service frequency bands Radiocommunications service frequency bands Transmit 1 1 900 MHz to 1 920 MHz Receive 1 1 900 MHz to 1 920 MHz Transmit 2 5 855 MHz to 5 875 MHz Receive 2 5 855 MHz to 5 875 MHz The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference.
