Rohde & Schwarz TSML Details
Rohde & Schwarz TSML
The R&S TSML family of radio network analyzers from Rohde & Schwarz is the ideal choice if you want to carry out quick, efficient, precise and cost-effective measurements in order to optimize your mobile radio network.
The R&S TSML family of radio network analyzers allows you to choose the instrument that optimally matches your specific requirements. Four different types are available, each designed to cover a specific application.
The measurement data can be collected and statistically evaluated by the Rohde & Schwarz R&S ROMES software. In addition, customer-specific software can be used with the R&S TSML due to an open user interface.
R&S TSML-C for CDMA2000 1x and IS-95
R&S TSML-G for GSM
R&S TSML-CW for CW Power measurements
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
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
Mobile phones can only “see” what the base station tells them to see
o Hidden neighborhoods
o 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
o No costs
o 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
o Calibration is possible
Use of only one unit for different networks and applications
Cheaper compared to many dedicated units
