Network meshes wireless and powerline comms

14 October 2015 Telecoms, Datacoms, Wireless, IoT

Greenvity Communications has developed technology that implements IEEE 802.15.4 wireless and wideband powerline communication (PLC) on a single chip, providing a highly reliable communications link for commercial building and industrial applications. Called ‘Hybrid Mesh’, the system enables always-connected links that penetrate concrete walls, extend range and cover entire buildings.

Said to be the first technology of its kind in the industry, Hybrid Mesh is the mixed-medium operation and algorithm between wireless and PLC that supports multiple hops for range extension, bridging and self-healing. To date, standard methods of mesh networking have been wireless only, or single-medium, presenting a challenge when concrete walls degrade wireless signals and inhibit communication throughout the building.

Modules utilising the new technology rely on an algorithm to make dynamic decisions on whether powerline or wireless is the better medium in the current environment. Each node repeats the same data to the next node – selecting PLC when wireless strength is weak, and choosing wireless when the PLC signal is degraded due to circuit breakers or noise.

The first Greenvity modules with Hybrid Mesh operation are the GV7011-MOD for commercial and industrial applications, and the GV-LED-11 smart LED controller and general IoT controller. Available now, both modules are powered by Greenvity’s GV7011 Hybrii-XL single chip with integrated Hybrid Mesh.

The GV7011-MOD can be used in air conditioners, heaters, appliances, solar inverters,

energy management and home/building security. The GV-LED-11 enables on, off, dimming and colour tuning that can control all LED and non-LED lights in the market.
