Abstract
A method for coordinating Wireless Avionics Intra-Communication (WAIC) communications with a radio altimeter signal includes monitoring a frequency band and recording a sequence of time stamps, each time stamp of the sequence of time stamps corresponding to a time at which a strength of the radio altimeter signal exceeds a threshold signal strength in the frequency band. The method further includes calculating time stamp intervals between successive time stamps to produce a sequence of time stamp intervals, and identifying a pattern of time stamp intervals in the sequence of time stamp intervals. The method further includes coordinating the WAIC communications with the pattern of time stamp intervals to avoid interference with the radio altimeter signal.
