R&S®TSML Radio Network Analyzer
Specified drive test solution for open user measurement software
Key Facts
The
The
The measurement data can be collected and statistically evaluated by the Rohde & Schwarz
- 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 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
- 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
