Based on signal strength recommendations, a good 5G signal is typically considered to be an RSRP (Reference Signal Received Power) value falling within the range of -80 dBm to -90 dBm.
RSRP is a crucial measurement in 4G and 5G networks that indicates the average power received from a single cell site reference signal. It's one of the primary metrics used to determine mobile signal quality and strength. Lower (more negative) dBm values represent weaker signals.
According to recommendations from Teltonika Networks wiki regarding mobile signal strength, the categories for signal quality based on RSRP are as follows:
| RSRP Range | Signal Strength |
|---|---|
| >= -80 dBm | Excellent |
| -80 dBm to -90 dBm | Good |
| -90 dBm to -100 dBm | Fair to poor |
| <= -100 dBm | No signal |
Therefore, to have a good 5G connection, you would ideally want your device's reported RSRP value to be between -80 dBm and -90 dBm. Values better than -80 dBm are considered excellent, while values worse than -90 dBm suggest a weaker signal that may impact performance.
