Received Signal Strength Indicator (RSSI) What do all these letters mean? Let’s figure it out! So, let’s go to the web interface of a mobile device and find the values of RSSI, SINR, RSRP and RSRQ. An acceptable RSSI value for GSM communication may be too low for 4G networks. Parameter estimation also differs depending on the generation of cellular communications. For example, the signal of GSM networks is usually measured with a single RSSI indicator, while 4G networks actively use all four parameters listed above.

It often happens that your modem model displays only a part of the values or one specific value in the web interface. Unfortunately, not all cellular devices are able to show all the listed values. It is important to know what these abbreviations mean in order to properly adjust the outdoor antenna of a modem, 4G router or repeater and get a stable and fast cellular connection.

Various values such as RSSI, SINR, RSRP, and RSRQ are used to determine the strength and quality of a cellular signal.

What is RSSI, SINR, RSRP, RSRQ? How does this affect signal quality?
