LPRS Radio Module from Circuit Design

LPRS has introduced its radio module from Circuit Design Inc. The MU-2-R embedded radio module operates at 434MHz and brings together industrial quality and reliability. The MU-2-R offers 128 RF channels and data speeds up to 4.8kbps with a transmission range from 500 to 700m. The design is based on an RFIC to ensure very competitive pricing. A number of useful functions are available as standard. These include an RF Test command for evaluating radio environmental conditions at installation site, which allows measurement of received signal strength and floor-noise and packet test measurement of RF communication quality. Transmission power may be user selected between 1mW to 10mW to avoid interference with other RF networks. And the new module offers long-range communication from battery power, at 10mW the MU-2-R has a range of greater than 600m.



The CDI MU-2-R offers enhanced error correction by using the Reed-Solomon code has which offers strong data recovery for errors caused by burst noise and can improve the receiver sensitivity by more than 5dB. Reed-Solomon code is also used on CD’s, satellite communications and digital TV broadcasting. With a wide operating temperature range, from –20ºC to +65ºC the MU-2-R is ideal for industrial applications.
