Radiometrix has developed the TR3M high-end multi-channel narrowband transceiver, which operates in the European 868MHz band.Wireless communications specialist Radiometrix has developed the TR3M, a high-end multi-channel narrowband transceiver that operates in the European 868MHz band (though custom variants for any 3MHz frequency block from 860-870MHz are available on request). It supports data rates of up to 5kbits/s, and has a usable range of over 500m. A built-in 1200 baud modem allows a wireless communications system to be quickly and easily implemented. Current consumption is 85mA for the transmitter and 30mA for the receiver, while the receiver sensitivity is -118dBm (for 12 dB SINAD). The module fits into a compact 59x38x10mm package. It meets the most recent class 1 specifications published for EN 300 220 and fully complies with EN 301 489-3. This product is highly suited to 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, barcode scanners, data loggers, industrial telemetry/telecommand, environmental monitoring equipment, high-end security/fire alarms, and vehicle data up/download.
