TR3M narrowband transceiver

The TR3M from Radiometrix is a high-end multi-channel narrowband transceiver that operates in the European 868 MHz band (though custom variants for any 3 MHz frequency block from 860-870 MHz are available).

It supports data rates of up to 5 Kbps and has a usable range of over 500 m. Employing a 1200 baud dumb modem it allows transmission across 80 different channels.

Current consumption is 85 mA for the transmitter and 30 mA for the receiver, while the receiver sensitivity is -118 dBm (for 12 dB SINAD). It conforms to EN 300 220-3 and EN 301 489-3.

The transceiver is suitable for low-power applications where existing wideband modules have insufficient range or where an upgrade to multi-channel operation is needed.

It can be incorporated into the system designs and communication infrastructure of handheld terminals, heavy vehicle/machine remote controls, bar code scanners, data loggers, industrial telemetry/telecommand, environmental monitoring equipment, high-end security/fire alarms and vehicle data up/download.
