G.hnem devices offer performance of up to 1 Mb/s and can operate in the CENELEC as well as the FCC bands. Improvements incorporated into G.hnem include significant blocking of impulsive noise, improved cross-phase signal propagation, and increased robustness under challenging power line conditions.
The ITU-T milestone enables silicon and system developers to design new products that utilize G.hnem PLC for an array of smart grid applications, including Automatic Metering Infrastructure (AMI), building automation, electric vehicle (EV) communications, as well as electric grid monitoring, and management links.
For in-home applications, the use of G.hnem-enabled devices in a Home Area Network (HAN) promotes extremely cost-effective yet highly capable networking of home appliances and devices.
The HomeGrid Forum has actively promoted the G.hnem standard, says Lantiq’s Dr. Vladimir Oksman, Chairman of the HomeGrid Forum’s Smart Grid Working Group. “We are delighted that the ITU-T has been able to develop the G.hnem Recommendation in just a year. This is a great step forward in collaboration between the ITU-T, the IEEE, SAE, ISO/IEC and HomeGrid Forum, with HomeGrid Forum leading in the ITU-T’s development of this next generation of PLC. This new Recommendation is a significant move as it represents the ITU-T’s first step in the smart grid arena, promoting interoperable devices and opening new global markets to innovative PLC products. The HomeGrid Forum has been one of the leaders in the ITU-T’s development of this next generation of PLC.”
Malcolm Johnson, Director of the ITU Telecommunication Standardization Bureau, adds: “Reaching Consent for G.hnem PHY and DLL Recommendations is a significant milestone and demonstrates just how effectively this industry can work together for the benefit of everyone. We particularly acknowledge the hard work of the HomeGrid Forum, whose members have embraced this important work from the outset and have shown sustained support and commitment in helping us reach this stage.”
HomeGrid Forum is a global, non-profit trade group promoting the International Telecommunication Union’s G.hn and G.hnem standardization efforts for next-generation home networking and smart grid applications. For more information, visit www.homegridforum.org.
