Ultra narrow band radio solution a key technology in Pay-Smart(tm) meters


Cambridge, UK, — (METERING.COM) — December 8, 2008 – The Cambridge-based electronics and communications design consultancy Plextek, has announced that its ultra narrow band (UNB) radio telemetry technology is being utilized in the AMPY Pay-Smart(tm) metering solutions from Landis+Gyr.

Based on the AMPY meter’s performance in initial trials, Landis+Gyr has recently won a $52 million contract from Arizona utility Salt River Project – the third largest public power utility in America – for the provision of a further 300,000 units.

Plextek is responsible for the development of the UNB communications system modules featured within the AMPY Pay-Smart(tm) meters and the associated base stations.

The AMPY Pay-Smart(tm) metering system allows customers to view real time costs and charges on their account, as well as reducing costs for the supplier by allowing them to take meter readings from a central hub.

"We have been working with Plextek for several years on the development of this innovative two-way communications technology. The UNB system performance meets the unit cost and radio coverage that the customer needs," said Jonathan Elmer, CEO of Landis+Gyr AMPY Solutions. "The resulting network-wide economies of scale were a significant factor in securing the contract extension with the Salt River Project."

"We are delighted that Plextek’s UNB technology components have helped pave the way for Landis+Gyr’s recent contract win and this very significant deployment," said Mark Hunter, Program Manager at Plextek. "Plextek’s UNB technology is optimised for long distance, low power applications where the data transmission rate is low which makes it perfect for two-way meter communications. With more emphasis being placed on energy efficiency, wireless meter systems will start to become a key part of people’s homes."
