LPRS - New low-power wireless module offers long-range capability

LPRS, one of Europe's leading suppliers of short-range wireless solutions has announced availability of the latest series of wireless modules from Circuit Design. The MU-2-R is an embedded low-power radio modem for transmission of serial data and operates at 434MHz. The new MU-2-R is just 36mm x 26mm x 8mm making it almost half the size of the existing MU-1-R

The MU-2-R wireless module is controlled by simple dedicated commands leaving the user free to concentrate on developing the transmitting and receiving programs for their system. For communication protocols the MU-2-R has a standard protocol and an error correction protocol, which performs error correction on the receiver side. The error correction protocol uses Reed-Solomon code that has strong error correction ability even in environments prone to burst errors. This ensures the user can configure highly reliable systems compared to conventional radio modems.

Transmitting and receiving data and issuing commands employ a UART interface with a single-chip CPU. In addition the module may be controlled via the COM port (RS232C format) of a computer, minimising development times. The MU-2-R is designed to reduce design difficulties involving high frequency components, allowing the user to embed it in their system with peace of mind.

A battery-operated 10mW MU-2-R covers a range of 600 metres or more. If the application requires greater range, the MU-2-R can be used as a relay station without any additional components. For long range applications up to 10 relay stations may be used, making it possible to gather data from and control equipment in remote locations.

Peter Cubbage, sales director, LPRS, said: "The new Circuit Design MU-2-R wireless modules are a welcome addition to our product range and will be particularly useful for security and control systems where low power consumption is required and long data transmission distances are involved. We have a great deal of experience with Circuit Design products and can offer application advice and design support to any of our customers who wish to use this advanced wireless module."

The Reed-Solomon code (RS code) is one of several FEC block codes; it has strong error correction ability and the characteristic of correcting data errors caused by burst noise. Reed-Solomon codes are used in compact disks, satellite communications, and digital TV broadcasting. The MU-2 uses Reed-Solomon code for FEC, which reduces errors occurring due to burst noise and/or noise at low received signal level, and it improves the receive sensitivity of the equipment by more than 5dB

Standard features of the new Circuit Design MU-2-R include R&TTE compliance, low voltage and low consumption current (ideal for battery operated applications), 1:1, 1:N, and N:N systems can be built by flexibly setting link parameters, local access to the status of radio waves and field noise at the target station and source station, standby mode to save the power of systems, field status can be checked in real time using RSSI information in the packet data, a function to lower the output power (antenna power) from 10mW to 1mW is provided for effective use of radio waves. Selectable RF power between 1mW and 10mW allows the user to limit the communication area so that several networks do not interfere with each other.

Typical applications for the new Circuit Design MU-2-R include, serial data transmission, energy monitoring, data monitoring devices, hand-held terminals, barcode reader, housing equipment control, telecontrol, warning systems, remote control for construction machinery, display devices, motor control, lifters, remote control of fire alarm equipment, telemetry, security systems, water level monitors for rivers etc., says the company.

Radio Modules Bring Re-Cycling Robots

Foundation offers LPRS-Robotics, the maker of the United Kingdom animatronics devices easy radio modules for wireless cycler, the state of the art presentation robot. Specially designed and built for the environment and education charity Waste Watch, cycler is used to their message of prevention of waste reduction, reuse and recycling in schools in Britain.

LPRS Radio Modules Bring Re-Cycling LifeTo cycler robots for recycling education programs in schools a "handler" is required, he said that this should be done by sending commands through a hidden radio transmitter powered by easy-Radios . Cycler five micro-controllers for the brains and nervous systems, a reader MP3 audio file, the amplifier and speakers to speak to him, and seven for the electric motors to move.

The manager can turn cycler move his arms, his head movement and has full control of the MP3 player that allows highly interactive dialogues instead.

Between what is said to do, cycler runs his own integrated personality that makes him look around, move his eyes to blink, while moving his head and arms. For practical reasons cycler is not allowed to drive, unless ordered to do so by his manager. This program allows the personality of the manager are both hands while cycler to move and speak, in general, look at what makes life easier for the presentation by keeping the audience's attention.

To date, it is estimated that the Foundation cycler Robotics robots visits 3 schools a day, some 750,000 were children and are an excellent way to their young audience's attention during the presentations.

David Buckley, managing director of the Foundation-Robotique comments, "My original drawings were based on chipsets and wireless modules that promised ease of use. In practice, I discovered I had to spend much time layers of software error correction to achieve a degree of reliable wireless connectivity. After I found easily 433MHz modules Radio transmitter and receiver, I thought, I 'I had no mistakes. I even turned off the error correction, I had to use and easy-Radio has not stopped working. simple Radio is easy to use, reliable, and I recommend it to anyone looking for a solution for wireless control. "

Barry Gillibrand, Managing Director of LPRS comments: "The experience of the Foundation-Robotics is a typical example of the simple answer to our Radio. An out-of-the-box and stress-free solution to replace cables over short distance wireless modules. Our software is simple and easy to use and ensure reliability, error-free wireless

communications".

LPRS - Wireless module is 55% smaller and costs less than predecessor

The new MU-2-R embedded RADIO module operates at 434MHz and brings together industrial quality and reliability while having dimensions of just 50mm x 30mm x 9mm it’s only 55% the size of the existing MU-1-R. Manufactured by Circuit Design (CDI), it is now available from LPRS.

The MU-2-R offers 128 RF channels and data speeds up to 4.8kbps 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 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 even greater range additional modules may be installed as relay stations.

”CDI are 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," said Barry Gillibrand, managing director, LPRS. "SRD’s offer price and performance benefits over systems based on Zigbee or Bluetooth and LPRS have 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 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 –20C 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, says the company.
