Scanning Receivers

Scanning Receivers (or just "Scanners") are passive RF signal receivers designed to provide detailed information on propagation, signal strength, interfering signals, and other characteristics of the RF network. Scanners emphasize accuracy, speed, and sensitivity in order to provide rapid collection of data for both very weak and very strong signals. Typical radio access network (RAN) measurement capabilities and applications of scanning receivers include:
  • High measurement accuracy and resolution.
  • Demodulation and decoding capabilities
  • Spectrum analysis
  • Location stamps using built-in GPS
  • Simultaneous measurements of all parameters on multiple pilots or cell IDs on multiple carriers
  • Measurement of all pilots or cell IDs, not just the active set and neighbour list
  • Measurements independent of the network state, non-intrusive to the network and unaffected by activity or problems in the network (blocked/dropped calls, incorrectly configured neighbour lists, network registration problems, etc.)
  • Measurement of the synchronization channel
  • Calculation and reporting of time offset or delay of a pilot or cell ID in reference to GPS time
  • Detailed measurements in multi-path conditions
    • more rake fingers in WCDMA
      • delay spread
      • UE-agnostic MIMO network characteristics such as channel correlation
  • Measurements over a wide range of Io (total received power density) or carrier Received Strength Signal Indicator (RSSI) values
  • Tests GSM, CDMA, EVDO, WCDMA, LTE-FDD, LTE-TDD in the same drive.
