RSRQ (Reference Signal Received Quality) in decibels (dB) measures the quality of the received signal in a cellular network, particularly in LTE (Long-Term Evolution) and 5G networks. It combines information from the signal strength (RSRP) and interference levels to provide an indication of how well the network is performing in terms of signal quality. A higher RSRQ value (less negative) signifies better signal quality and less interference.
What is RSRQ?
RSRQ (Reference Signal Received Quality) is a metric used to assess the quality of the received signal in cellular networks, such as LTE and 5G. It is derived from both the received signal strength (RSRP) and the level of interference present. RSRQ provides a measure of the signal quality by indicating how much interference and noise are affecting the received signal, which helps in evaluating the overall network performance and user experience.
A good RSRQ value typically falls between -10 dB and -15 dB. Values closer to 0 dB (less negative) indicate better signal quality and less interference, while more negative values suggest poorer signal quality and higher levels of interference. An optimal RSRQ ensures better network performance, including higher data throughput and more stable connections.
RSRQ is measured by calculating the ratio of the reference signal’s received power to the total noise and interference affecting that signal. This involves taking into account the RSRP (Reference Signal Received Power) and the interference power to determine the quality of the signal received by the device. The measurement is expressed in decibels (dB), where a higher RSRQ value (less negative) reflects better signal quality.
RSRP (Reference Signal Received Power) in dBm measures the power level of the reference signal received by a device in a cellular network. It indicates the strength of the received signal and is crucial for evaluating signal coverage and network performance. RSRP is expressed in decibels milliwatts (dBm), with higher values (less negative) representing stronger signal strength and better network coverage.
