NOTE: Important! The higher the RSSI number, or the less negative, the stronger the signal strength (for example, a value of -48 is greater than -78). The minimum value acceptable for network operation is RSSI = -85 dBm. RSSI (Received Signal Strength Indicator) is an indicator of the signal power level received by the modem. A negative or close to zero values LTE connection is impossible to establish, or it will be deficient in speed and quality.
NOTE: Important! The higher the CINR value, the better the signal quality.Ī negative CINR value will mean more noise in the received signal than the effective signal. The minimum value acceptable for stable network operation: CINR = 10 dB. The CINR value is measured in dB.Ī positive CINR value means that there is a more effective signal than noise. To measure the signal quality, pay attention to the 'Signal (CINR / RSSI)' values.ĬINR (Carrier to Interference + Noise Ratio), also called SINR (Signal to Interference + Noise Ratio), is the ratio of the signal level to the noise level (or simply the signal to noise ratio).
On the 'System dashboard' page in the 'Internet' section, you can see the current status of the LTE connection.Ĭlick 'More details' to display more information. Keenetic routers with a built-in 4G/3G modem ( Keenetic Hero 4G and Runner 4G models) or a USB port to connect external USB modems allow you to connect to the Internet via a mobile operator's network.
