Abstract: Data packets are transmitted from a terminal of a broadband radio communication system. For each transmission cycle in a transmission period data is received at a data interface of the terminal and buffered, and transmission of radio signals comprising the received data is enabled on expiry of a repetition interval from the start of a previous transmission. The repetition intervals are controlled to reduce a proportion of the transmission period for which transmission may occur at an allowed pulse repetition interval of a radar with which the terminal may interfere. The presence of radar pulses is checked during a wait period for each cycle while the terminal is not transmitting. If radar pulses are present, the transmission of radio signals which may interfere with the radar pulses is inhibited.
