Analog Devices has announced that Elster has selected ADI’s ADF7241 smart metering solution for use in gas and electricity meters as part of a nationwide energy efficiency initiative sponsored by the British government. Under the Smart Metering Implementation Programme, more than 50m smart gas and electric meters will be installed in all homes and small businesses across the U.K. by 2020.

ADI’s ZigBee-based ADF7241 smart metering solution, which includes the ADF7241 transceiver and a ZigBee network protocol stack provided by Exegin Technologies, will provide the wireless connectivity for Elster’s meters.

A smart meter accurately measures how much energy is consumed or generated, and communicates with the local utility company for power monitoring, billing, and other purposes. ADI’s ADF7241 solution enables smart gas, electric and water meters to provide improved customer billing accuracy and advanced power quality monitoring, reducing operating costs for the utility company, allowing savings to be passed on to under-pressure consumers.

“Elster selected ADI’s ADF7241 smart metering solution because of the performance, design flexibility and product future-proofing it provides,” said Joerg Klatte, Head of Smart Meter Solutions, Elster Gas. “ADI is providing a uniquely flexible package that allows Elster to use a ZigBee software stack for both 2.4-GHz and 868-MHz bands. In particular, it enables Elster to maximise the battery lifetime of our smart gas meters while achieving better than state-of-the-art radio performance.”

“ADI’s radio technology combined with Exegin’s ZigBee stack offers a smart metering solution that supports multiple PHY devices in a single PAN, including 868MHz and 2.4GHz in the United Kingdom’s dual-band radio solution,” said Leslie Mulder, President, Exegin. “This is ideal for smart meters installed in Great Britain because it provides an agnostic approach that offers maximum flexibility with the stack operating as a coordinator, router, or end-device.”
