How It Works

Bluetooth is the foundation for transformative wireless connectivity

Bluetooth® is a low-power wireless connectivity technology used to stream audio, transfer data and broadcast information between devices. There are two flavors of Bluetooth technology, Basic Rate/Enhanced Data Rate (BR/EDR) and Low Energy (LE).

Basic Rate/Enhanced Data Rate (BR/EDR)


Bluetooth BR/EDR enables continuous wireless connections and uses a point-to-point (P2P) network topology to establish one-to-one (1:1) device communications. Bluetooth BR/EDR audio streaming is ideal for wireless speakers, headsets and hands-free in-car systems.

Low Energy (LE)

Bluetooth LE enables short-burst wireless connections and uses multiple network topologies, including point-to-point, broadcast and mesh.


Point-to-point (P2P) is a network topology used to create one-to-one (1:1) device communications. Bluetooth LE P2P topology is ideal for data transfers and well suited for connected device products, such as fitness trackers and health monitors.


Broadcast is a network topology that establishes one-to-many (1:m) device communications. Bluetooth LE broadcast topology optimizes localized information sharing, making it ideal for beacon solutions, such as point-of-interest (PoI) information and item and way-finding services.


Mesh is a network topology for many-to-many (m:m) device communications. Bluetooth LE mesh topology creates large-scale device networks tailor-made for building automation, sensor network, asset tracking and any solution where multiple devices need to reliably and securely communicate with one another.
