Why is a radio network analyzer needed at all?

  • Measurement speed and accuracy is considerably higher than mobile phones can deliver in order to represent the real physical nature of the radio network environment
  • The mobile phones can only “see” what the base station tells them to see
    • Hidden neighborhoods
    • Pilot pollution and interference causes are not detectable
  • Multiple carrier/channel selection is possible in order to provide a complete picture of the available RF environment (mobile phones provide only one carrier and one operator)
  • The use of only one unit for different networks and applications is more cost-effective than many dedicated devices (broadband application 80 MHz to 4 GHz)
  • Not only RF level scanning, but in addition demodulation of BCH (i.e. layer 3) Conclusion: independent from network registration and SIM card
  • Spectrum analysis provides detection of external interferences
  • Higher level accuracy, use as reference to mobile phones measurements
  • The reason for an abnormal end of call (dropped call) can never be found by the mobile phone affected
