Patent ID: 8886794

Claim:
A network comprising: at least one signal analyzer of a plurality of signal analyzers comprising a wideband receiver characterised by an operating bandwidth, each signal analyzer associated with a predetermined location and providing signal analysis of at least one user-specified frequency band of a plurality of user-specified frequency bands to determine whether signals detected by the at least one signal analyzer within the at least one user-specified frequency band comply with at least a user-defined policy of a plurality of user-defined policies stored within a memory of the at least one signal analyzer of the plurality of signal analyzers; wherein, each user-defined policy relates to a power, frequency, and time mask for the at least one user-specified frequency band and comprises a series of settings, each setting comprising: a band index relating to a frequency capture band within the at least one user-specified frequency band, a trigger type for the band index, a time domain level for the band index, and an averaging period for the setting defined by a number of consecutive signal samples; and a spectral line defined by a sample within output samples of a Fourier Transform applied to the signals received within the at least one user-specified frequency band, a trigger type for the spectral line, a value for the spectral line, and a persistence interval defined by a number of consecutive signal samples; the plurality of user-specified frequency bands having a fixed bandwidth significantly smaller than the operating bandwidth; and at least one server of a plurality of servers, each server only receiving a trigger signal from a signal analyzer within a predetermined subset of the plurality of signal analyzers when signal analysis denotes a predetermined condition with respect to compliance to the at least one user-defined policy.
