2.2 LTE Signal Strength
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.

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 will use on the router on a mobile phone. Go outdoor with a mobile phone. Disable Wi-Fi connection and check the network type and signal bars. Then choose a location with a strong and stable 4G-LTE signal reception. For more information about the signal tests, please refer to the signal test tutorial.
4G Signal Quality
The numerical value of 2G and 3G networks is RSSI standard.
The LTE network is RSRP standard. RSRP is Reference Signal Receive Power.
The signal values are negative numbers. The number that closer to zero means a stronger signal. For example, -90dB is stronger than -100dB.
