Bluetooth mesh is new Bluetooth technology and is different from what people use in their phones. It is suitable for small buildings, lighting systems, fire alarm devices and sensors.
It is a wireless network of many devices connected to each other capable forwarding messages back and forward.
Bluetooth mesh transforms Bluetooth from a typical point-to-point, star-based network into a true mesh networking topology. If you have a device within range of another device on such a network, the range of both devices is extended. Keep on adding nodes, and the range keeps extending.
While mesh networking is nothing new, it is only now starting to be adopted by leading luminaire manufacturers.
Bluetooth mesh will make the lighting control 'box' redundant, says Simon Slupik, the chief technology officer of Silvair and chair of the Bluetooth mesh group. "That box – when you think about it – is a computer with software. We’re simply putting a copy of that software in every light."
Bluetooth is handling global standardisation for lighting control application. That basically mean that consumer can buy luminaries from different manufacturers and they will be compatible with each other.
Range of the mesh is as far as it needs to be, the whole building or collection of buildings because it is not limited to a radio range. In terms of the range between devices is hundreds of meters.
This system is, to some extents available today - there are manufacturers that implemented Bluetooth antennae in their lighting fittings and can be controlled with app on your phone.
Even though the main application is for the lighting control, in the future it is expected to broaden its field to smart buildings - collecting data from wireless sensors and using that data to drive automated processes and systems in the building.
