More on these measurements in separate service mode sections.

For 3G service mode, there are three relevant measurements:
For 3G service mode, there are three relevant measurements:
*RSSI - indicates the received signal strength
*RSSI - Received Signal Strength Indicator
*EC/IO - indicates the downlink carrier-to-interference ratio (signal quality)
*EC/IO - indicates the downlink carrier-to-interference ratio (signal quality)
*RSCP - indicates the received signal code power
*RSCP - indicates the Received Signal Code Power
The RSSI standard values for 3G are basically the same as 2G

For 4G service mode, there are four relevant measurements:
*RSSI - indicates the received signal strength
*RSSI - Received Signal Strength Indicator
*RSRP - the Reference Signal Received Power is the power of the LTE Reference Signals spread over the full bandwidth and narrowband
*RSRP - the Reference Signal Received Power is the power of the LTE Reference Signals spread over the full bandwidth and narrowband
*RSRQ - Reference Signal Received Quality is a C/I type of measurement and it indicates the quality of the received reference signal (similar to EC/IO)
*SINR - Signal to Interference plus Noise Ratio (A minimum of -20 dB SINR is needed to detect RSRP/RSRQ). Indicates the throughput capacity of the channel. As the name implies, SINR is the strength of the signal divided by

==How do I check the signal quality on a RUT device?==
===WebUI===
The fastest and easiest way to find out your '''RSSI''' is by checking the Overview window of your router's WebUI (web user interface). The Overview window can be reached simply by accessing your router's WebUI (the default log in information is: address: '''192.168.1.1'''; Username: '''admin'''; Password: '''admin01'''). Once you've logged in, you will be redirected to Overview window automatically. The Overview window contains widgets that display various information summaries about the status of your router. The RSSI value can be checked by looking at the Mobile widget that is located in the top right corner of the Overview window by default.

To get more detail about signal quality, you may want to check the Mobile Information section, which is located in '''Status -> Network -> Mobile'''. The Mobile Information window contains information about your mobile connection. Concerning signal quality, it displays Signal Strength ('''RSSI'''), '''RSRP''', '''RSRQ''' and '''SINR'''.

===SSH and CLI===
To get the most detailed information about your signal quality values you can use ''gsmctl'' commands when logged in via CLI or SSH.
