For example, the RSSI value includes the signal of neighboring base stations, internal and external interference and noise. In modern networks, this indicator does not allow you to say anything about the quality of the signal, because it takes into account not only the useful signal of your cell, but also all the secondary signal in the measured frequency range. RSSI is measured in decibels milliwatts (dBm) and indicates the strength of the signal received by your device. RSSI is the value of the signal strength received at the antennas of the device. 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.
Due to significant differences between 2G, 3G and 4G standards, not all indicators are applicable to all mobile networks. The tables of estimated parameters below are provided for informational purposes and are based on the experience of our engineers and customers However, they are not absolute, as cellular communications quality is also affected by other external factors – base station utilisation, operator equipment bandwidth, etc. These metrics help you determine the best location for your outdoor antenna and provide an overall assessment of your RF environment. When evaluating link quality using RSSI, SINR, RSRP and RSRQ values, you should consider the following factors: In this case, it is impossible to find out the numerical indicators, since the scale is formed based on internal algorithms and calculations of the device software. In the worst case, a mobile device may not be able to display numerical values for signal strength and quality at all. 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?
