1. In a radio frequency (RF) communications system having a plurality of control modules having transceivers operating at various frequencies within a predetermined range, a method for selecting an operating frequency from within said range for use by a new control module seeking to commence operation within said system, said method comprising the steps of:

  • scanning, by the new control module, at its intended location of operation, a set of frequencies within said range;

    storing a table of information corresponding to signals sensed during said scanning;

    evaluating the stored information to determine a number of interference sources associated with each scanned frequency; and

    selecting that frequency from within the set having the least number of associated interference sources for use by the new control module.
