Low Power Radio Solutions (LPRS) is now delivering production quantities of its Easyradio Advanced (ERA) wireless modules, which are suitable for applications such as building and home automation, sports and leisure systems, security, vehicle logistics and asset tracking, environmental monitoring and energy control, industrial control and smart metering.

This latest generation of wireless radios incorporates the new version of the company’s Easyradio software protocol, which is intended to remove the complexities of developing a software interface to the ERA modules.

According to the company, existing users of Easyradio Version 02 will be able to upgrade their projects to the ‘advanced’ versions as required.

Key features and specifications

  • Free flash firmware upgrade tools allow customers to install any required updates
  • Bandwidth may be adjusted between 100kHz and 12.5kHz
  • Digital received signal strength indication (RSSI) reduces the requirement of the host system to handle analogue-to-digital measurements
  • Users can program transmission frequency (up to 132 channels), output power (up to 10mW), serial data rate (up to 115.20Kbps maximum), digital RSSI, carrier detect, FSK and ASK modulation and bandwidths (12.5kHz, 25kHz, 50kHz, 100kHz)
  • ERA range is comprised of 433–434MHz and 868–920MHz multi-frequency transmitter and transceiver modules plus a development kit with a USB interface

Low Power Radio Solutions

LPRS Ltd (Low Power Radio Solutions) is a privately owned ISM band
‘easy-Radio’ radio module manufacturer and distributor of Circuit Design,
Prowave and Airwave transmitters, receivers, transceivers and antennas.
Their sales team is based in Witney, Oxfordshire where as their Technical
Centre is in Warrington, Cheshire.

easy-Radio comes in transmitter, receiver and transceiver modules and as a
pendant transmitter. Operating frequency for the modules is either
433-434MHz (ER400 series) or 868-870MHz for Europe and 902-928MHz for USA
(ER900 series). As they’re based on the Chipcon’s RF ICs, the modules also
provide user-programmable features including frequency of operation, power
output and data rate.

The easy-Radio (ER) ERx00TS transmitter, Erx00RS receiver and Erx00TRS
transceiver incorporate ‘easy-Radio’ technology to provide high performance,
simple to use radio devices that can transfer data over a range of up to 250
metres Line Of Sight (LOS). Furthermore ‘easy-Radio’ technology allows
frequency, data rate and power output to be optimised for customer specific
applications. The embedded software reduces design and development time
