Quadlogic Controls is North America’s leading provider of Power Line Communications metering technology. The company’s digital electric Advanced Intelligent Smart Submetering Systems are in use in high-rise office, residential, commercial, and industrial facilities across the U.S. and Canada. In the face of rising energy costs, deregulated markets and complex energy pricing, the data provided by Quadlogic’s metering systems is critical to an organization’s energy management decisions. Quadlogic’s patented Power Line Communications technology utilizes a building’s existing power lines to transmit metered data, so no additional wiring or meter readers are required. When the system was first developed more than 25 years ago, it used a serial device via a telephone modem to enable communications with the outside world. As technology advanced and customer preference shifted from telephone service to Internet, the ability to offer network-enabled metering technology became an imperative if Quadlogic was to remain competitive. The decision was made to integrate the capability into its next-generation Power Line Communications system.
