Tiny IoT radio for smart meters
A tiny radio module for connecting smart meters to a local hub or gateway has been designed by Cambridge-based Amiho Technology in partnership with Rohm subsidiary Lapis semiconductor.
By Richard Wilson - Electronics Weekly, Oct. 28, 2015 –
The AM060 radio module, which measures just 17.8 x 20.2mm, operates at the Wireless Meter-Bus standard of 868MHz. It has built in data flash specifically for smart metering and other IoT applications.

For security the companies have added enhanced AES 256 encryption.
The module is based on the Lapis ML7345 radio which supports a range of frequencies from 169MHz up to 900MHz.
"The ML7345 radio incorporated allows a versatile frequency selection which means it can be used in a variety of applications and regions where Wireless Meter-Bus and other sub-1GHz ISM bands have been adopted," said Hiroshi Kume, senior product marketing manager at Rohm Semiconductor in Germany.
The AM060 module will be exhibited on the Rohm Semiconductor stand at European Utility Week in Vienna (3-5 November).
The module will be supported by an evaluation board allowing rapid and can be used to test different radio modules on the same board.
