Wireless module is 50 per cent smaller
29 April 2008
Integrator of industrial wireless communications, LPRS, has announced the introduction of the latest radio module from Circuit Design.
The MU-2-R embedded radio module operates at 434MHz and offers 128 RF channels and data speeds up to 4.8kbps with a transmission range from 500 to 700m. Furthermore, dimensions of 50mm x 30mm x 9mm mean that it’s only 55 per cent of the size of the existing MU-1-R.
The new design is based on an RFIC and a number of functions come 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. For an even greater range, additional modules may be installed as relay stations. Typical applications will include long-range wireless communications and industrial communications within single buildings or multiple buildings on an industrial site.
The new CDI MU-2-R offers enhanced error correction by using the Reed-Solomon code 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 satellite communications and digital TV broadcasting.
