Analog Devices buys powerline comms technology

18 March 2009 News

Analog Devices has acquired powerline communications technology to add to its portfolio of products for energy metering applications. The company has acquired the PowerBUS Rhino powerline communications technology and all related patents, hardware and software from Domosys, a privately held Canadian company.

This technology is effective for the advanced metering infrastructure (AMI) systems that utilities need for ‘smart-grid’ applications that acquire and communicate consumption information for electricity, gas and water. AMI systems provide two-way meter communications, allowing instructions to be sent to residences for multiple purposes, including realtime pricing data, demand-response actions and remote service disconnects.

Powerline communications can transform any standalone meter into a device that can be controlled or monitored either locally or remotely. Signals are sent and received over existing power lines or twisted-pair wires, reducing the need for the installation of new wires or the building of new infrastructure. Analog Devices will develop new products incorporating the PowerBUS Rhino technology and announce these offerings under the Analog Devices brand later this year.
