Reference Signal Received Quality (RSRQ)
The RSRQ (Reference Signal Received Quality) value is another important metric for evaluating your 5G connection. It provides information about the quality of the received reference signals in relation to the total received power.
The RSRQ value is calculated from the RSRP (the strength of the desired signal) and the RSSI (the total received power, including interference and noise) (Formula: RSRQ = N * RSRP / RSSI, where N is the number of resource blocks). Simply put, the RSRQ tells you how good the useful signal is compared to all other signals (interference from other cells, noise).
A good RSRP value alone does not guarantee a good connection if there are many interfering signals present at the same time. This is where RSRQ comes in: A poor RSRQ value (more negative) indicates high interference or high network load, even if the RSRP value itself is good. For optimization, RSRP and SINR are often more directly usable, but RSRQ provides valuable information about the interference situation.

| > -10dB | Excellent |
| < -10dB | Good |
| < -15dB | Fair |
| < -20dB | Critical |
