R&S®TSMU Radio Network Analyzer
Compact drive test solution
Key Facts
In mobile radio networks, it must be possible to obtain accurate information about the receiving conditions of a mobile unit at any place and any time. The R&S® TSMU radio network analyzer from Rohde & Schwarz provides outstanding performance independent of standards in a small unit. It meets the demands of network operators, regulatory authorities, railway carriers and infrastructure suppliers.
The measurement data is collected and statistically evaluated by the R&S® ROMES software from Rohde & Schwarz.
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
