  • Patent number: 8207826
    Abstract: Systems and techniques for generating data showing a signal environment experienced by a radio frequency identification (RFID) communication device. A transceiver within the communication device sweeps through a frequency range of interest in order to receive signals within the frequency range. Depending on the nature of the signals of interest, the signals detected may be reflected signals generated in response to a carrier signal produced by the communication device, or active signals produced by active sources. Baseband analysis is performed in order to detect and identify reflective signals, and spectrum analysis is performed in order to detect and identify active signal sources.
