Bluetooth is a short range wireless technology that operates in the unlicensed Industrial, Scientific and Medical (ISM) 2.4 GHz radio frequency band. Bluetooth 5 includes three major enhancements to Bluetooth low energy: increased data rate (2 x the speed), extended range (4 x the distance) and enhanced advertising capability. Bluetooth mesh enables many‑to‑many Bluetooth low energy networking solutions.

Bluetooth 5

The latest version of the specification, Bluetooth 5, includes three major enhancements to Bluetooth low energy: increased data rate (2 x the speed), extended range (4 x the distance) and enhanced advertising capability. Two of these features will come with a software upgrade and one (extended range) requires new hardware.

The recently introduced Bluetooth mesh enables many‑to‑many Bluetooth low energy networking solutions. Bluetooth mesh is available as a software update to Bluetooth low energy and can be used with any of the Bluetooth low energy versions 4.0, 4.1, 4.2 and 5.0.

Mesh extends the coverage area significantly, even further than Bluetooth 5, because Bluetooth nodes can forward messages acting as relays in a cooperative network.

Bluetooth 5 and Bluetooth mesh open up completely new applications for Bluetooth. Industrial sensor networks, building automation, street lighting, environmental monitoring, and many other applications will require only a single host node to collect, control and manage the data and the mesh network.

Overview of Bluetooth versions and their features:
