The mobile modem sensitivity is -101dBm, we should input at least 2-bar 4G LTE signals for the router.
Insert the SIM card will use on the router on a mobile phone. Go outdoor with the mobile phone. Disable Wi-Fi connection and check the network type and signal bars. Then choose a location with a 4G LTE network reception and strong signal strength for the EZR33 router.
The numerical value of 2G and 3G networks are RSSI standard. And LTE network is RSRP standard which is Reference Signal Receive Power.
The closer the number is to zero, the better the reception, so -90dB is a stronger signal than -100dB.
There are various mobile networks, 2G, 3G, 4G, and even the newest 5G NR networks. To get a fast and stable internet connection on the EZR33 outdoor router, we shall input a strong 4G LTE signal to the router.
