Success Story – MikroTik LtAP mini LTE kit – safe as a bank!

Rate post

Techno Trade from Uzbekistan had a contract to upgrade the ATM network of a major banking company. The main task was to connect 50 ATMs to the central office. All ATMs were supposed to receive Internet via 3G/LTE and use an encrypted channel to form a single network.

Here’s what they did.

The project was carried out using a VPN tunnel. For this setup, we used 50 MikroTik LtAP mini LTE kits as VPN clients. As for the VPN server - we used a CCR1036-8G-2S+. The diagram shows that we used L2TP with IPsec for the VPN network.

An L2TP VPN server with IPsec was configured on the main router. VPN clients with two SIM cards (from different mobile operators) were installed on MikroTik LtAP mini LTE within the ATMs. If the SIM1 would suddenly lose connection, SIM2 from the other carrier would provide it.

Always satisfying to see a well-thought-out project with failovers. Better safe than sorry!


In case if you missed the convenient LtAP mini series, here’s a quick reminder:

  • 2.4 GHz AP in a rugged case
  • Two SIM slots
  • Built-in GPS
  • Serial port for other devices
  • Several powering options (PoE, DC jack, microUSB)
  • Can be used with external LTE and GPS antennas of your choice

It is a perfect solution for real-time tracking. MikroTik has provided a simple tracking application example in the RouterOS documentation to help you get started.
