The TRM250 is an industrial-grade USB Cat M1 modem. With its small, lightweight frame, its strong, rugged design and its capability of being powered by 5v USB, this modem is an extremely versatile device, designed to allow for low capacity remote monitoring in a variety of environments; particularly those where such a thing would be very difficult with bigger, more power-consuming devices.

The TRM250 also has a external antenna port to allow for a mobile LTE antenna to be connected, improving signal strength and performance.
