Signal strength measure RSRP, RSRQ and SINR Reference for LTE Cheat Sheet

RSRP, RSRQ and SINR are three important parameters used to measure the quality of a cellular network signal in LTE (Long-Term Evolution) technology.


RSRP refers to Reference-Signal-Receive-Power and measures the power of the reference signal received at the antenna of the device. It provides an indication of the radio link quality between the device and the serving cell.


RSRQ (Reference Signal Received Quality) measures the quality of the reference signal received by the device. It indicates the level of interference on the radio link, and helps to assess the quality of the connection.

and SINR

SINR (Signal to Interference plus Noise Ratio) is a metric that measures the ratio of the desired signal power to the sum of the power of all other interfering signals and noise. It provides a measure of the quality of the received signal and the ability of the device to correctly decode the data..

Please refer to the table for indicative values:
• when RSRP changes from >= -80 to -70dBm it is an improvement of 10 dBm.
• when RSRQ changes from >= -10 to -6dBm it is an improvement of 4 dBm.

Have a look on the internet on how to put your phone in ‘Field Test Mode’. Eg for an iPhone connected to Vodacom in South Africa dial *3001#12345#* from your Phone.

It is Phone and Network Provider specific. Tip: make sure to switch off Wi-Fi, Click the Right-Hand Side Tab and find ‘Serving Cell Meas’ and you will see various parameters and amongst those you will see RSRP, RSRQ and SINR.
In summary, these three parameters are used together to provide a complete picture of the quality of a cellular network signal and the performance of the connection.

For those interested can have a look at this video where Dr Andre Fourie discuses RSSI, RSRP, RSRQ and SINR in more detail in a video titled “What is RSSI, RSRP, RSRQ and SINR”.
