RSRQ (Reference Signal Received Quality) in 5G is a measure of the quality of the received signal, calculated as the ratio of the Reference Signal Received Power (RSRP) to the total received power, including interference and noise. It helps evaluate the efficiency of the network in delivering a strong and clear signal to the user equipment.
What is a good RSRQ?
A good RSRQ typically ranges from -9 dB to -12 dB or better in 4G and 5G networks. Values closer to 0 dB indicate better signal quality, while values lower than -12 dB generally suggest poor signal quality, which can lead to reduced data rates and connectivity issues.
5G RSRQ (Reference Signal Received Quality) functions similarly to its role in previous network generations by providing an indicator of signal quality. In 5G, RSRQ is used to assess the efficiency of the network in delivering a reliable signal, particularly in environments with high levels of interference or during handovers between cells.
The difference between RSRQ and SINR is that RSRQ measures the quality of the signal relative to the total received power, including interference and noise, while SINR (Signal-to-Interference-plus-Noise Ratio) measures the strength of the desired signal relative to interference and noise. RSRQ is a broader measure of signal quality, while SINR focuses specifically on the interference aspect, offering more insight into network performance in noisy environments.
RSRP (Reference Signal Received Power) in 4G is a measure of the power level of the reference signal received by the user equipment. It is used to determine the signal strength of the LTE network and is a key factor in assessing network coverage and deciding which cell the device should connect to. Higher RSRP values indicate stronger signals and better connectivity.
