New features for secure, accurate distance measurement improve convenience and security for devices connected via Bluetooth

Bluetooth® Umbrella Organization Bluetooth Special Interest Group (SIG) Introducing Bluetooth® channel detection. New security and accuracy features improve the usability, security and protection of devices connected via Bluetooth. Bluetooth® channel detection opens up many new application possibilities for developers and users alike by enabling true distance awareness in a variety of everyday devices.

“Bluetooth® technology has become an integral part of daily life,” said Neville Meijers, CEO of the Bluetooth Special Interest Group. “When connected devices measure the distance between each other, many new application scenarios will expand.

The new functionality offers decisive advantages for a wide range of applications:

Bluetooth® “Find My” Solution To locate personal items such as keys, wallets, backpacks or luggage, Bluetooth® tags can be attached to them. In addition, more and more Bluetooth devices now have a “Find My” feature, which turns the device connected to Bluetooth into a “Find My” device. In the future, through the use of Bluetooth® channel detection, developers will be able to add true distance awareness capabilities to Find My devices, which will improve the accuracy and usability of these solutions and users will be able to locate their locations more accurately and easily Lost items.

Bluetooth® digital key solution Bluetooth® technology is already used in vehicles, doors, gates, safes and bicycles to enable keyless entry and create secure locking mechanisms. Developers can use Bluetooth® channel detection to improve the security and usability of digital key solutions. For example, true distance awareness can be used to ensure that a lock is only opened when an authorized device is within a certain distance.

“We look forward to incorporating new features into our upcoming Bluetooth digital key specification,” said Feng Yunsheng, chief secretary-general of the Smart Car Connectivity Open Alliance (ICCOA). “The introduction of Bluetooth® channel detection fulfills ICCOA’s mission.” and passengers with greater comfort, performance and safety.

Ren Feng, Secretary-General of the Intelligent Car Connectivity Industry Ecosystem Alliance (ICCE), added: “ICCE is committed to formulating industry standards, promoting cross-industry collaboration, and realizing seamless smart in-vehicle services. Therefore, we are already studying whether to incorporate Bluetooth® channel detection technology It is included in the ICCE standard for car keys as one of the distance measurement methods and is expected to be integrated.

In addition to Find My and digital key solutions, Bluetooth® channel detection has the potential to support and enhance other applications and change the way people interact with the connected world.

“Bluetooth® channel detection technology is suitable for consumers, enterprises and industries alike,” said Andrew Zignani, senior research director at ABI Research. “Imagine Bluetooth-enabled mice, keyboards and game controllers that can automatically Switch between devices.

advantage Bluetooth® channel detection offers three key benefits, especially for developers looking for a simple and secure way to add high-precision distance measurement capabilities to connected devices:

• accuracy: Bluetooth® channel detection uses phase-based ranging (PBR) to accurately measure the distance between devices connected via Bluetooth. It achieves accuracy in the centimeter range even over long distances. This meets the needs of most applications and allows even the simplest connected devices to take advantage of true distance awareness.
• Safety: As the number of connected devices grows, ensuring the integrity of these connections becomes increasingly important. Bluetooth® channel detection uses a robust multi-layered security solution that includes a secondary measurement method – round trip time (RTT)-based distance limits. In doing so, it creates an additional layer of security against sophisticated man-in-the-middle (MITM) relay attacks.
• omnipresent: Bluetooth® technology is integrated into all important devices, such as smartphones, tablets or laptops. With Bluetooth® channel detection, developers can now add true range awareness to Bluetooth devices without developing additional wireless technology.

Joonsuk Kim, executive vice president of the System LSI Connectivity Team at Samsung Electronics, said: “Bluetooth® channel detection can provide true distance perception for various Bluetooth devices, opening up new possibilities for distance-sensitive applications in various industries.” “With Bluetooth® With channel detection, we can provide centimeter-level accuracy to help our customers find important items, thereby improving the performance of ‘Find My’ applications. A few examples of the transformative potential of Channel Detection, with many more applications waiting to be realized.

Bluetooth® channel detection is part of the new Bluetooth core specification version 6.0. For more information on Bluetooth® channel detection and its applications, see www.bluetooth.com/de/.

Via Bluetooth SIG Founded in 1998, the Bluetooth SIG is a not-for-profit trade association that oversees Bluetooth® technology. The Bluetooth SIG supports more than 38,000 member companies, enabling members to collaborate to create new and improved specifications that expand technology, advance global interoperability and strengthen brands through a world-class product certification program. They do this by increasing awareness, understanding and acceptance of Bluetooth® technology. For more information, see: https://www.bluetooth.com/channelsounding/.
