MaxLinear and Corinex to use G.hn for open smart meter design

October 23, 2017 // By Nick Flaherty
Chip maker MaxLinear has teamed up with Corinex, a Canadian supplier of broadband smart meter and smart grid infrastructure, to use standard ITU-T G.hn powerline technology for smart metering and other smart grid applications.

The G.hn design will allow vendor independence across broadband data links on power networks for smart grid applications. It uses existing G.hn chips, reducing time to market and leveraging existing investments in G.hn technology currently used in the broadband carrier, consumer and Industrial segments.

During the initial phase in Q1 2018, Corinex, with assistance from MaxLinear, will develop a software application layer supporting the existing family of MaxLinear BPL chips (DSS95xx family). The application layer will include support for IPv6, SNMPv3, SSH, FTPS, COSEM Security Suite 0 and TACACS+ protocols, providing a robust set of cybersecurity features in the Smart Meter industry. The system will combine communication and smart metering functionalities and will be available from Corinex to OEMs to create their own low-voltage metering or medium-voltage backhaul designs.

G.hn is an international standard for broadband communications over any wired media with rapidly growing adoption across multiple markets (telecommunication service providers, cable companies, consumer home networking and industrial networking). By using the existing MaxLinear G.hn chips with Corinex's Smart-Grid optimized software, OEMs can tap into the cybersecurity features required by the Smart Grid industry.

“The combined G.hn solution will provide OEM’s with reference design of the industry validated interoperable meter ready for mass manufacturing including advanced utility features, communication with programmable frequency use, state of the art LDPC forward error correction, self-organizing-network mesh capabilities, support for low-voltage and medium-voltage topologies, AES-128 wire-speed encryption, secure firmware upgrade, and broadband data rates to enable real-time meter control and reading in low-voltage cells with up to a thousand of smart meters,” said Peter Sobotka, CEO of Corinex.

“The broadband capabilities provided by G.hn will help utilities to ensure their networks are ready for the business and regulatory challenges expected by 2020 and beyond, while enabling a wide range of services such as real-time power usage information to consumers, load management, distributed energy generation/storage, electric vehicle charging and other IoT applications,” said Chano Gómez,
