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?

If you want to check it to be certain, find the MCS-index and look it up:Ĩ02.11n datarates are based on a number of factors (MIMO,GI,20 vs 40 MHz etc.), hence the MCS-index. 300: it is probably because of GI (Guard Interval), using a shorter guard interval will give higher troughput, but it's usually turned off -> probably because of compatibility. Note: RSSI is a percentage and not a linear representation of how many dBm is actually reaching the card.

For reference: 0 - No connectionģ00 - 802.11n on 5.0 Ghz (Normally I see this connect at 270 for some reason) The number to pay much more attention to is the Transmit Rate - the transmit rate will drop if you have too much noise or interference or if you are too far away from the base station. My laptop which I can roam around the house with never goes lower than -60 and never higher than -51. Currently my iMac is 20 feet (line of sight) from my wireless base station and fluctuates between -57 and -58 and is connected at full speed. Generally the higher (closer to 0) the better, and the closer to -100 the worse. RSSI or received signal strength indication can go from 0 to -100 (for Apple - other vendors can measure it differently as RSSI has no stated units.
