Abstract: A radar waveform generator, having a radar waveform selection assembly, permitting a user to select a waveform by picking any one out of a set of less than 50 center frequencies named in a 5 GHz Wi-Fi standard and any one out of a set of less than 10 pulse repetition waveforms. Further, the radar waveform generator has an electronic network producing and emits the selected radar waveform.

Abstract: A machine which accepts a frequency set and ranks each frequency of said frequency set relative to other frequencies of said frequency set, according to susceptibility to intermodulation product interference from said set of frequencies.

Abstract: A method of assigning channels (each having a center frequency from a frequency set) to a set of sound sources for a live entertainment event performance, said sound sources having a hierarchy of importance to entertainment event success. First, the frequencies are ranked in terms of susceptibility to interference from intermodulation products created by the frequency set. Then, high importance sound sources are assigned the most reliable channels—that is, those having a center frequency that has a relatively low susceptibility to interference from intermodulation products.

Abstract: A device and method measures transmission efficiency of wireless RF energy packets for each 802.11 channel and relates these measurements to the presence of RF interference. The invention is implemented using a single computing device with an installed wireless network adapter that implements the CSMA/CA transmission protocol.
