The G.hnem standard, which creates specifications for AMI and in-home energy management, has entered the final stages at the ITU.
G.hnem includes two new recommendations: G.9955 (PHY and system architecture) and G.9956 (DLL) form the global G.hnem standard for low frequency (9-500 KHz) powerline communications (PLC) for smart meters, energy management systems, electric vehicle communications, control and home automation.
With this standard, device makers can deliver up to 1 Mbps and operate in the CENELEC as well as the FCC frequency bands.
A number of improvements, including impulse noise blocking, improved cross-phase signal propagation and greater robustness under challenging powerline conditions, have been incorporated into G.hnem.
ITU-T plans to gain final approval for both the G.9955 and G.9956 recommendations later this year.
