Signal strength for 5G connections
For 5G connections, the RSRP value determines signal strength.

RSRP (dBm) Measures signal strength from the tower. |
RSRQ (dB) Reflects signal quality, factoring in interference and noise. |
SINR (dB) Indicates how much usable signal exists compared to interference. |
