5.1 Signal Tests
Choose a stronger signal reception location for the EZR33 router. 4G LTE signal is much faster than 3G UMTS/WCDMA signal.
5.1.1 - FIND A LOCATION
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 a 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.
The numerical value of 2G and 3G networks are RSSI standards. 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.
5.1.2 - MOBILE NETWORKS
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. Please take note of signal bars and the symbol in the status bar of the mobile phone and compare it with the below chart.
Symbol | Mobile Networks | Internet Speed |
G | GPRS | 50 Kbits/s |
E | EDGE | 100 Kbits/s |
3G | 3G - UMTS / WCDMA / CDMA2000 | 2 Mbits/s |
H/H+ | HSPA (High-Speed Packet Access) | 10-100 Mbits/s |
4G (LTE) | 4G - LTE or WiMax | 100 Mbits/s+ |
5.1.3 - SIGNAL STRENGTH
In your mobile phone, you can read signal bars followed by carrier name and network symbol. To check more accurate signal strength, please use the below methods.
i. Check on Router
Insert a SIM card and log in EZR33 router admin, on the front page you can check the signal quality of the received mobile signals.
Since the mobile connection is in the first priority, on the first boot, the device information will take a few minutes to show completely.
i. Field Test on Phone
iPhone iOS 12
1. Go into the Phone app and switch to the Keypad. Dial *3001#12345#* and press Call button.
It will launch the field test mode on your iPhone.
2. In the latest iOS 12, tap on Serving Cell Measurements.
3. Look for Measured RSSI with numerical measurement of the iPhone 4G LTE cellular signal strength in dBm.
Android Smartphone
Go to Settings > About Phone > Status > SIM Status and numerical signal strength will be available on either network or status which depends on the model of phone.
You can also use signal test apps to check the mobile phone signal strength in Android phones.
