Data Concentrator Unit

Data concentrators collect data about energy consumption and other customer management information from smart meters connected via a wireless or power-line communication (PLC) network in residential or commercial buildings and route this data in real time to a smart grid backhaul network, Advanced Metering Infrastructure (AMI) or customer center for further analysis and processing.

ST offers a range of field-proven, programmable power-line communication (PLC) solutions to support a variety of specifically developed standards including G3-PLC, PRIME and Meters-and-More as well as sub-GHz wireless connectivity solutions supporting wM-Bus, LoRa and Sigfox low-power wide-area network (LPWAN) protocols.

In addition, our high-performance 32-bit STM32 microcontrollers and secure elements – for meter authentication – and high-efficiency AC-DC converters together with a comprehensive set of hardware and software evaluation and development tools can help developers design robust and reliable data concentrators.
