Want zu know if the end 4G Router works for you? perform a basic field prüfen on your mobile phone über using her mobile phone zu check die signal quality outside your house.

Du schaust: Mobile lte router test

To get much more accurate data, you re welcome disable die Wi-Fi link on her mobile phone. You tun können read signal bars followed über carrier name and network symbol.

You kann see what network kind you’re connecting zu (2G, 3G, 4G, LTE, etc.). Take klasse of signal bars und the symbol an the status riegel of your mobile phone and compare it with ns below chart.

The 4G routers kann connect zu 2G, 3G, and 4G mobile networks. However, zu get a fast speed und stable internet connection, we should input a durable 4G LTE signal zum the router. Zum example, if ns mobile symbol zu sein G/E/3G/H, the 4G router kann sein not work as well together it’s designed to. Please walk around to find an additional location that has the minimal 2-bar LTE signal reception.

To measure up mobile phone’s signal reception bei exact decibels instead of bars or dots, you can follow guidance zu enable the Field test Mode in mobile phones.

Decibel signal strengths möchte be negativ 2~3 digits. Unit of measurement zu sein dBm. If her phone nur a number such together 98, ns actual signal strength ist -98dB. The closer die number zu sein to zero, the better ns reception, deshalb -90dB zu sein a stronger signal than -100dB.

The number value von 2G / 3G / 4G H+ networks zu sein RSSI standard which is Received Signal stamin Indicator. LTE network is RSRP traditional which zu sein Reference Signal obtain Power.


Go into die Phone app und switch to ns Keypad. Dial *3001#12345#* und press Call button to launch the Field test Mode on your iPhone. In the iOS 14.8, tap die menu button on the top right corner.Click Serving cell Info, then nevigate zu Freq_band_ind. That is the LTE frequency band.Return to ns previous page und tap ~ above Rach effort and find ns RSRP value on the zuerst row.

Go into die Phone app und switch to die Keypad. Dial *3001#12345#* and press Call button to launch the Field prüfung Mode on her iphone. In die iOS 13.3, tap on LTE > Serving cell Info. Freq_band_ind is die LTE frequency band.Tap ~ above Serving cell Mass > Rsrp0 to check die LTE signal strength.

Go into ns Phone app and switch to die Keypad. Dial *3001#12345#* and press Call button to launch the Field prüfung Mode on your iPhone. In iOS 12, tap on Serving cabinet Measurements to check ns strength and band.

On google Play store, search for Network Cell die info Lite und install it.Make sure inserted a workable sim card an the phone, turn on general practitioners on ns phone, und open die above newly mounted APP.Tap top top Raw to check die frequency band and signal strength.

Go kommen sie Settings > about Phone > zustand > sim Status und numerical signal strength wollen be accessible on one of two people network or status which depends on the model of phone.

You can also use apps to nur signal strength an decibels in Android phones.

When ns 4G router is turned on v a workable sim card, log bei the 4G router admin, we can find ns modem device information on ns right column von the front page.

The cell phone modem model, IMEI number, und connection zustand are listed bei the machine column. Click ns “Reacquire” button we kann get ns updated modem information.

Since EV3117 firmware version, the mobile protocol has switched kommen sie “MobileData”. The “Signal Strength” changed kommen sie a portion number weil das easier understanding.

To read the exact decimal signal strength, you re welcome use ns below MMCLI commands on SSH terminal.


After logging bei the router admin, go zu System > Terminal. Enter the router user benennen root and router password, which does not shows trost when inputting, zu enter die command-line user interface on die web browser.

Verify Modem Sequence

mmcli -LTo list ns current modem.

If die router has notfall set nach oben a 4G connection, ns guardian module möchte automatically restart die modem. Die modem will disappear from the list temporarily. We kann use the below command to überwacht the modems.

mmcli -M Press Ctr+Z on ns keyboard kommen sie exit the überwacht status.

Check Signal Strength

mmcli -m 0 –signal-setup=30

Set die signal refreshing rate zu 30 seconds. You can change the interval zu 20 seconds über replacing 30 to 20.

mmcli -m 0 –signal-get

To list die decimal signal strength des the currently connecting network.

Insert a sim karte card, revolve on ns power, und log in the 4G router admin. On the right column of the former page, you kann check the modem machine information, including mobile network band und signal strength.

Click die Reacquire taste to get the updated signal toughness information.

The network band is die current mobile network connecting to.RSRP value zu sein the signal strength. When connecting to 3G WCDMA or UMTS network, please check ns RSSI value.

Since ns mobile link is bei the zuerst priority, on the zuerst boot, ns device info will take a few minutes to nur completely.


After logging in the router admin, go zu System > Terminal. Enter the router user nennen root and router password, which does not shows hoch when inputting, to enter the command-line interface on die web browser.

Verify simkarte Registration

Enter gcom command zu verify the sim karte card installation und registration.

If it shows SIM error, please check if the sim karte card is workable; if the simkarte card inserts in the exactly slot, ns default setting is used SIM1 slot.

If die Registration ist Failed, please examine if the simkarte card is already activated.

Check Signal Strength

Enter the below uqmi command zu check ns instant cell phone network type and signal stamin (unit zu sein dBm).

uqmi -d /dev/cdc-wdm0 –get-signal-info

The above uqmi command does not work under die 4G-PPP protocol.
