R&S®TSMQ Radio Network Analyzer

Just one drive test covers all standards

Applications

All major mobile network technologies – WCDMA, GSM, and CDMA2000® 1x – are supported in parallel. CW measurements can be done separately.

The R&S®TSMQ Radio Network Analyzer can deliver measurement results for up to three different technologies. For network optimization, you can measure interference, coverage, and carrier-to-noise ratio in one technology while scanning another technology for survey purposes. Thus, you can analyze a UMTS network during a drive test while simultaneously monitoring a GSM network for offline analysis or post-processing. You can even analyze a competitor's network during a major measurement within a single trip. As a mobile network operator, you can therefore always stay informed about competitor networks without incurring any additional costs.

The compact design and low weight of the R&S®TSMQ Radio Network Analyzer allow you to integrate it into a backpack for indoor measurements. Thus, you can analyze exhibitions, train stations, shopping malls, or public buildings at an unsurpassed level of performance and with maximum accuracy, just like when using drive-test tools installed in a vehicle. Moreover, the instrument's low power consumption enables it to be operated from a battery for up to four hours.

Why is a radio network analyzer needed at all?

  • Measurement speed and accuracy are considerably higher than what mobile phones can deliver in order to represent the real physical nature
  • Mobile phones can only “see” what the base station tells them to see
    • Hidden neighborhoods
    • Pilot pollution and interference causes are not detectable
  • Limited channels/carriers (one carrier per mobile and SIM card)
  • Layer 1 and layer 2 decoding for better troubleshooting
  • Spectrum analysis provides detection of external interferences
  • No SIM card identification is required
    • No costs
    • No capacity is allocated
  • Failure of a mobile phone leads to data loss
  • Measurements are independent of mobile chipsets and provide unbiased reference data
  • Higher level and time accuracy compared to mobile phone-based measurements
    • Calibration is possible
  • Use of only one unit for different networks and applications
  • Cheaper compared to many dedicated units
