Teltonika TRM250 – Industrial 4G LTE / NB-IoT / EGPRS Cellular Modem for IoT and M2M

The TRM250 is an industrial cellular modem with support for NB-IoT, LTE Cat-M1, and EGPRS (2G), designed for LPWAN connectivity in remote monitoring applications and communication upgrades of existing industrial equipment. It is deployed in projects where low power consumption, extended product lifecycle, and low total connectivity cost are the primary selection criteria.

Triple support for NB-IoT, LTE Cat-M1, and EGPRS provides maximum deployment flexibility — the modem adapts to available network coverage in the area, maintaining connectivity even in locations with limited infrastructure. Ultra-low power consumption makes it suitable for battery or solar-powered devices, significantly extending the operational autonomy of remote installations. The external antenna improves signal reception in environments with weak network coverage.

The USB interface simplifies integration into existing industrial equipment without complex hardware modifications — a critical advantage for communication modernisation projects on devices already deployed in the field. The ruggedised aluminium enclosure provides adequate mechanical and thermal protection for demanding industrial environments subject to temperature variations and physical stress.

Recommended for remote monitoring systems with low bandwidth requirements and extended autonomy, communication upgrades on existing industrial equipment, NB-IoT or LTE Cat-M1 based IoT solutions in areas with limited 4G coverage, and any application where long-term connectivity cost-efficiency takes priority over data throughput. The extended lifecycle reduces replacement frequency in large-scale distributed deployments.
