SRD module outperforms ZigBee and Bluetooth

Embedded radio module offers long-range communications from minimal battery power, with a range of better than 600m from 10mW output.

The latest radio module from Circuit Design is available now from LPRS.

The new MU-2-R embedded radio module operates at 434MHz and brings together industrial quality and reliability, and at just 50 x 30 x 9mm it is only 55% the size of the existing MU-1-R.

The MU-2-R offers 128 RF channels and data speeds up to 4.8Kbit/s with a transmission range from 500 to 700m.

The new 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 the 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 1 and 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 even greater range additional modules may be installed as relay stations.

Barry Gillibrand, Managing Director or LPRS, comments: "CDI is at the leading edge of short range radio module design".

"The new MU-2-R offers more performance in a smaller package and will be ideal for new applications emerging in industrial automation and building control".

"SRDs offer price and performance benefits over systems based on Zigbee or Bluetooth, and LPRS has the depth of engineering experience to make sure our customers get the best possible wireless solutions in the fastest development time".

The new CDI MU-2-R offers enhanced error correction using 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 CDs, satellite communications and digital TV broadcasting.

With a wide operating temperature range, from -20 to +65C the MU-2-R is ideal for industrial applications.

Typical applications include long-range wireless communications and industrial communications within single buildings or multiple buildings on an industrial site.
