G3-PLC Alliance launches the Certification Programme for first Hybrid PLC & RF Communication Standard!

Paris, France, March 12th, 2021. The G3-ALLIANCE Alliance, the world’s leading industry alliance for powerline communication in smart grid applications, now again takes the lead by developing and certifying the next generation PLC standard incorporating Radio Frequency (RF) capabilities. The G3-ALLIANCE Hybrid is the first industry hybrid standard offering extended capabilities in one seamlessly managed network over both media, PLC and RF. This way, the revolutionary hybrid profile provides an efficient and cost-effective solution for smart grid, smart city, industry and IoT applications. The G3-ALLIANCE Alliance is pleased to announce the launch of its certification programme for the hybrid profile. With this remarkable achievement, the first hybrid platforms and products are now under certification.

Marc Delandre, Chairman of G3-ALLIANCE Alliance, says, “The G3-ALLIANCE Alliance runs a very successful certification programme which now includes the hybrid profile. The interoperability of the G3-ALLIANCE Hybrid standard has already been demonstrated in 2020 among the chipsets from 5 leading international manufacturers: Microchip, Renesas, STMicroelectronics, Semitech Semiconductor and VertexCom Technologies. The hybrid specification has been published and from today, the hybrid profile is a new feature of our certification programme.”

The hybrid protocol stack is built using open standards IEEE 802.15.4-2015 in addition to the existing G3-ALLIANCE protocol. Each device in the mesh network can use PLC as well as RF for the communication. Depending on the actual conditions in the field, messages between two devices are sent over the ‘best’ available channel. The channel selection for each link in the network is done automatically and adjusted dynamically. This way, the hybrid profile provides an efficient and cost-effective solution for many applications and opens up new use cases as it extends the connectivity of G3-ALLIANCE to RF-only devices. The G3-ALLIANCE Hybrid profile is fully compatible and interoperable with existing G3-ALLIANCE implementations, so it is possible to mix hybrid and non-hybrid nodes.

“A proven and global certification programme allows for the sourcing of interoperable products from multiple suppliers and is a key requirement for any smart grid and IoT application. High-quality certificates will give both manufacturers and customers assurance that their devices have the correct implementation of the G3-ALLIANCE standard, that they are interoperable with other certified devices and meet the specified performance levels. Therefore we have spent a lot of time with our members, in close cooperation with our test laboratories LANPARK (France) and TÜV (Japan) to develop and implement tests for the hybrid PLC & RF profile and we are very glad we have now included this in our existing certification programme.” said Leon Vergeer – G3-ALLIANCE Alliance General Secretary.


G3-ALLIANCE is a proven Powerline Communication technology for smart grids used worldwide and offering the lowest total cost of ownership and independency on telco operators. G3-ALLIANCE facilitates high-speed, highly reliable, long-range communication over the existing powerline grid. It is standardized under ITU-T G.9903 and with its support of IPv6, G3-ALLIANCE will support powerline communications well into the future.

About the G3-ALLIANCE Alliance

The G3-ALLIANCE Alliance is a consortium created in 2011 to standardize and promote G3-ALLIANCE technology globally. Today, the G3-ALLIANCE Alliance counts more than 90 members that are international key stakeholders of the smart grid ecosystem, including utilities, semiconductor companies, equipment manufacturers and industrial companies. Together, they support, promote and implement the G3-ALLIANCE technology and established an industrial certification program to guarantee the interoperability of devices from different manufacturers.
