How is Configuration Performed in Mikrotik LTE (4G) Integrated Model Devices?

In places where there is no network infrastructure, we may have to have internet from GSM operators. Or even if there is a network infrastructure, we may sometimes need it in redundancy. Now, let’s get some information about Mikrotik LTE / 4G Integrated models.

Below is a list of models that support LTE / 4G.

These Mikrotik LTE 4G supported models:

  • SXT LTE kit
Mikrotik RBSXTLTE3-7 LTE Cat 3 LTE Modem
Mikrotik RBSXTLTE3-7 LTE Cat 3 LTE Modem

 

  • RBSXTR&R11e-4G
RBSXTR&R11e-4G
RBSXTR&R11e-4G

 

 

  • LHG LTE kit
MikroTik LHG LTE kit
MikroTik LHG LTE kit

 

  • wAP LTE kit
wAP LTE kit
wAP LTE kit

 

  • LtAP mini LTE kit
LtAP mini LTE kit
LtAP mini LTE kit

 

These products include integrated LTE / 4G Modem cards. The software updates of these cards are carried out differently from the RouterOS update. I will explain below how this update and configuration are.

LTE Device Configuration (6.41 and above)
APN information is required for LTE devices to work. You can get this information from the GSM operator of your country.

You are defining the newly created apn profile on your LTE modem.

To monitor the connection status of your LTE modem:

After the RouterOS version 6.41 version, a DHCP Client is automatically created for LTE devices. In addition, if there is no DHCP client for the LTE interface, you can do it with the following command.

You will need to masquerade to access the Internet from LTE Device.

To view information about the connection status of the LTE Device.

It displays the information about the connection status of the LTE Device as seen below.

For example, let’s assume that you need to direct the LTE connection directly to the subnet, in this case, we will use the Passthrough feature.

Suppose we need to define this differently for 2 interfaces. If the 1st port is down, let the 2nd port be activated.
In this case, thanks to this model, interfaces can output from the 1st or 2nd interface by using the 1 or 2nd apn.

Pulling information with AT Commands

You can use the following command to learn the Imei information of the LTE Interface.

Modem Firmware update process and device’s LTE Firmware should be checked.

R11e-LTE version (“MikroTik _CP_2.160.000_v006”) is required. We take the modem to firmware Update mode.

We expect the device to download its firmware from Mikrotik’s site (the file with about 5 Mb may take 3-4 minutes).

If we want to view the download status:

(Note: This download process is performed over the LTE modem, so the LTE device must be connected to 3G / 4G network.) When the update is complete, you should see a printout like the one below.

After completing the update process, we reset the LTE modem.

After the reset, the LTE interface will disappear for 1-2 minutes and come back. if your query later.

You can see that the version has been updated as the R11e-LTE version (“MikroTik_CP_2.160.000_v008”).

Note that this process will be made easy in new versions, just like the RouterOS upgrade.

Warning: During this process, if the device is powered off or the internet connection drops because it cannot receive the update, there is a possibility that the LTE modem of your device is broken.
This may make the product out of warranty. You should be careful before doing this, or if you do not have enough information, I suggest you do not do this.

I hope it has been a useful article.
