2.1 Signal Quality

Good 4G LTE mobile signal quality is a fundamental factor in getting a stable and fast internet connection over the mobile network.

Mobile Networks Mode

There are various mobile networks, 2G, 3G, 4G, and even the newest 5G NR networks. Please take note of signal bars and the symbol in the status bar of the mobile phone and compare them with the below chart.

4G (LTE)

Fourth generation or Long term evolution also known as LTE or WiMax



Third Generation also known as UMTS / WCDMA / CDMA2000

If signal bars get more than 1 bar you can use voice call


Signal Strength

We should input a "Fair" signal level for the 4G router (refer to the below chart), which equals approximately 2-bar 4G LTE signals on a mobile phone.

You can run a basic test on a mobile phone. Insert the SIM card that is going to use on the router on a mobile phone. Disable Wi-Fi on the mobile phone and go around to check its network type and signal bars. Then choose a location with a strong and stable 4G-LTE signal reception.

Please refer to the signal test tutorial.

The numerical value of 2G and 3G networks is RSSI standard.

The LTE network is RSRP standard. RSRP means Reference Signal Receive Power.

The signal values are negative numbers. A number that is closer to zero means a stronger signal. For example, -90dB is stronger than -100dB.
