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.įor 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”. 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. It is Phone and Network Provider specific. Eg for an iPhone connected to Vodacom in South Africa dial *3001#12345#* from your Phone. Since this measures only the reference power, we can say this is the strength of the wanted signal. Have a look on the internet on how to put your phone in ‘Field Test Mode’. RSRP is the linear average of all the red part power. when RSRQ changes from >= -10 to -6dBm it is an improvement of 4 dBm.when RSRP changes from >= -80 to -70dBm it is an improvement of 10 dBm.Please refer to the table for indicative values: It provides a measure of the quality of the received signal and the ability of the device to correctly decode the data. 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. RSRP does a better job of measuring signal power from a specific sector while potentially excluding noise and interference from other sectors. It indicates the level of interference on the radio link, and helps to assess the quality of the connection. RSRQ (Reference Signal Received Quality) measures the quality of the reference signal received by the device. A 4G Nemo Outdoor wireless analyzer was used to collect the Reference Signal Received Power (RSRP) signal data based on the identified campus road maps. It provides an indication of the radio link quality between the device and the serving cell. RSRP refers to Reference-Signal-Receive-Power and measures the power of the reference signal received at the antenna of the device. RSRP, RSRQ and SINR are three important parameters used to measure the quality of a cellular network signal in LTE (Long-Term Evolution) technology.
