Short Answer
Mobile network reception is evaluated using technical values such as RSRP, RSRQ, SINR, ping, download, upload, and coverage per room. The bar display on the phone is only a rough indication. For buildings, offices, underground garages, and critical areas, structured measurement points, provider comparisons, and documentation are necessary. This allows one to determine whether WiFi Calling suffices or if mobile in-house coverage is needed.
Anyone conducting a speed test in only one location often overlooks gaps in coverage, poor uploads, or issues with specific providers.
Important Measurement Values
| Measurement Value | Relevant For? |
|---|---|
| RSRP | Signal strength of the cell. |
| RSRQ | Quality and load conditions. |
| SINR | Interferences and usability for data. |
| Download/Upload | Practical data performance. |
| Telephony Test | Voice quality and call setup. |
Measurement in the Building
- Define building plan, relevant rooms, and providers.
- Establish measurement points per floor and critical area.
- Collect telephony, data, and signal values separately.
- Consider times with typical usage.
- Document results and derive solutions.
Typical Measurement Errors
- Measure only one provider.
- Check only download while ignoring upload and telephony.
- Measure only at the window.
- Use bar display as proof.
- No measurement points and no documentation recorded.
FAQs
Can I measure mobile network reception with my phone?
For a first assessment, yes. For professional building planning, structured measurement and documentation are required.
What does RSRP mean?
RSRP describes the reception strength of an LTE cell. Comparable values exist for 5G.
What does SINR mean?
SINR describes the ratio of useful signal to interference and noise. It is important for data quality.
Why is a speed test not sufficient?
It only shows a snapshot and does not reliably explain whether signal, load, provider, or building is causing the problem.
