Ukrainian company Militech Group has developed the “HRIM” LTE modem for controlling unmanned aerial vehicles and ground-based robotic systems via mobile networks. The device is designed to boost signal strength in areas of poor coverage and provide communications at ranges of up to 45 km. The company announced the development on November 4 to DOU.
“HRIM” is intended for use as an alternative or backup communications channel in conditions where access to Starlink satellite internet is restricted. The company began its development back in 2024, anticipating possible communications problems at the front.
In October 2026, Ukrainian military personnel reported data transmission delays via Starlink. This creates problems for controlling FPV drones and ground-based robotic systems that use satellite communications to carry out combat missions.
Technical Specifications of the “HRIM” LTE Modem
According to Militech Group, the device is built on the basis of a standard MikroTik LTE modem supplemented with a signal amplifier.
Key modem specifications:
| Parameter | Specification |
| Connection type | LTE |
| Transmitter power | Up to 1.5 W |
| Stated range | Up to 45 km |
| Base | MikroTik LTE modem |
| SIM cards | Two slots |
| Antennas | Selected separately |
The manufacturer states that the transmitter power of the “HRIM” is approximately six times greater than that of a standard LTE modem, which is around 0.25 W.
The increased power is intended to help maintain communications with unmanned systems in conditions of weak mobile network signal. The device also supports switching between base stations.
The basic configuration does not include antennas. These are selected individually depending on the type of drone or ground-based robotic system.
Militech Group has stated that the modem has undergone testing and is ready for use in combat conditions.
Supply to Drone Manufacturers
Throughout 2026, Militech Group is assembling batches of “HRIM” modems in quantities of 500 units or more for Ukrainian unmanned systems manufacturers.
The company also plans to assist with integrating the device into unmanned platforms and selecting optimal mobile networks for their operation.
From January 2027, the modem is expected by the manufacturer to become available to foreign customers.
It is claimed that “HRIM” is set to become one of the options for providing backup communications channels for Ukrainian unmanned systems. Unlike Starlink, the LTE modem depends on the ground infrastructure of mobile operators, so its effectiveness will be determined by the availability of cellular network coverage in the area of operation.
