Choose Location

Good mobile signal quality is fundamental to getting a stable and fast internet connection over the mobile network. Please choose a location for the 5G router that has a fair 4G/5G signal reception.

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

The chart below shows signal quality ranges for 4G/5G cellular networks. The main factors are RSRP and SINR. Ensure RSRP and SINR have a “Fair” signal level to maintain a stable mobile internet connection. Typically speaking, 3-5 bars indicate fair/good signals, and 1-2 bars indicate a poor signal that might sometimes lose connections. No bars mean no cellular signal was detected.

You can run a basic test on a mobile phone. Insert the SIM card into a mobile phone, disable Wi-Fi, and then walk around to check its network type and signal bars. Then, choose a location with strong and stable signal reception.

Quality RSRP (dBm) RSRQ (dB) SNR/SINR (dB)
Excellent > -80 > -10 > 20
Good -80 to -90 -10 to -15 13 to 20
Poor -90 to -100 -15 to -20 0 to 13
Bad < -100 < -20 < 0

Definition of Signal Strength

Excellent: Maximum speed and data throughput.
Good: Stable connection and good data throughput.
Poor: Maintain data connection with restricted throughput.
Bad: Connection drop or unable to keep a stable connection.
