Rohde & Schwarz TSML Radio Network Analyser (Drive Tester) for WCDMA, GSM and CW

The R&S® TSML family of radio network analysers 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 analysers 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-W for WCDMA
• 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 analyser 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
• 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
