Proven and Robust Communication for Smart Metering, Smart Grids and IoT
The G3-Alliance
Our Alliance is dedicated to advancing two communication technologies: G3-PLC and G3-Hybrid. These technologies, standardized under ITU-T G.9903, utilize existing powerline infrastructure as well as radio for cost-effective data communication.
G3 Standard:
A Robust Alternative to Wi-SUN and PRIME for Smart Metering & IoT
G3 offers cost-effective, secure, and long-range communication for smart metering, grid automation, and industrial IoT; outperforming technologies like Wi-SUN and PRIME in many deployments. As an open and standardized solution, G3 enables seamless connectivity, interoperability, and scalability across energy networks worldwide.
