G3-PLC Alliance Released the Final Version of the 2022 G3-Hybrid PLC+RF Dual-Mode Standard

Vertexcom Assists in the Formulation of Dual-Mode Frequency Hopping Spec

Hsinchu , Taiwan – February 3, 2023 - The G3-Hybrid PLC+RF dual-mode is the industry's first dual-mode communication standard. It provides enhanced capabilities for smart grid and IoT applications in a seamless management network over two kinds of media, which sets an important milestone for the communications industry. In January this year, the G3-PLC Alliance announced that the plugfests have successfully demonstrated interoperability of the G3-Hybrid. The latest plugfests aimed to test the interoperability between three G3-PLC dual-mode solutions including frequency hopping, and successfully realized seamless communication of dual-mode frequency hopping. Vertexcom Technologies Inc. (Vertexcom) is the only chip manufacturer in greater China who participated in the plugfest and is a contributor to the G3-PLC communication specification.

In the G3-PLC interoperability plugfest, Vertexcom and its partner Hexing Electrical Co., Ltd. (Hexing) worked together. Hexing used Vertexcom's G3-Hybrid PLC+RF dual-mode chip to make modules and assisted Vertexcom to participate in the test. In addition to the existing G3-PLC protocol ITU-T G.9903, the G3-Hybrid dual-mode protocol stack is jointly built with the open standard IEEE 802.15.4-2015. Each device in the mesh network can use PLC as well as RF to communicate. Depending on the actual situation on site, the messages between two devices will be sent through the "best" available channel.

Dr. HH Li, the president of Vertexcom stated that Vertexcom is honored to be invited by G3-PLC Alliance to participate in the specification formulation of the G3-PLC protocol PLC+RF hybrid dual-mode. Vertexcom has long been committed to the development of PLC power line communication technology and RF wireless communication technology. The hybrid dual-mode communication solution provides a flexible, high-speed, stable, and reliable dual-channel communication network for smart grid transmission.

G3-PLC Alliance expresses its gratitude to all active members of the technical working group for their hard work and contributions. Leon Vergeer, the G3-PLC Alliance General Secretary, said the Alliance is very pleased to have published the final version of the G3-PLC 2022 specification.
