High-accuracy indoor location services
Bluetooth® Direction Finding enables devices to determine the direction of a Bluetooth Low Energy (LE) signal, thereby enabling the development of Bluetooth proximity solutions that can understand device direction as well as Bluetooth positioning systems that can achieve centimeter-level location accuracy.

Bringing established, time-tested methods for determining signal direction to a proven, trusted radio
Radio direction finding has been in practice since the early twentieth century and is used in systems to support everything from aviation and nautical navigation to wildlife tracking.
Bluetooth Direction Finding brings this well-established practice to one of the most trusted and widely deployed radio technologies in the world.
Bluetooth Direction Finding includes two different methods for determining signal direction, Angle of Arrival (AoA) and Angle of Departure (AoD).
Bluetooth AoA Use Cases
Factories tracking material workflow and hospitals tracking the location of expensive mobile equipment
Manufacturing facilities ensuring workers do not wander into unsafe areas
Sports teams tracking the real-time location and performance of athletes
Bluetooth AoD Use Cases
From airports to museums to convention centers, Bluetooth AoD-based indoor positioning systems can enhance the visitor experience.
Autonomous Guided Vehicles (AGVs)
AGVs need to know where they are to get where they need to go. Bluetooth AoD-based indoor positioning systems let them know, precisely.
