Ta Ling Micro Electronics Takes The Lead In Supporting The Bluetooth Channel Detection

At the moment of intelligence, accurate positioning technology is becoming a link connecting the real world and the digital world.Bluetooth Technology Alliance (Bluetooth Sig) officially announced the release of the Bluetooth channel detection.This technology is a new feature in the Bluetooth core specification 6.0, which significantly improves the distance measurement accuracy based on Bluetooth -based, laying the foundation for a series of innovative applications.As the leader of the industry, Ta Ling Micro Electronics proudly announced that its overall solution based on the latest SOC chip has taken the lead in integrating this technology and joined hands with the positioning technology of intelligent equipment to move towards the new height.

Exceed In the 25 -year development process, Bluetooth technology evolved from simple wireless alternative technology to making countless connection devices a possible intangible clue and integrated into daily life.It is expected to ship 1.35 billion units in 2024.Although Bluetooth is known for its outstanding wireless communication capabilities, RSSI -based ranging technology can only provide rough distance information.In order to improve the ranging abilityThe accuracy and security of the Bluetooth Technology Alliance have launched the Bluetooth channel detection after unremitting efforts.This is a new protocol stack, which contains a new physical layer designed for safe and accurate ranging (PHY).It usually can achieve +/- 50 cm measurement accuracy within 100 meters. It gives many Bluetooth connecting devices a real distance perception ability, opening a world full of possibilities for developers, so that they can give full play to their imaginationCreate a new experience, and these experiences will further enhance our connection with the equipment and the surrounding world.When the connection device has the ability to perceive, a series of new possibilities came into being.

Bluetooth channel detectionApplication area

The field of Bluetooth channel detection technology is widely used, covering multiple key areas:

BluetoothFind my solution

Attach Bluetooth tags to personal items, such as keys, wallets, backpacks, or luggage, this is justThe beginning of Find My phenomenon.At present, more and more Bluetooth devices are embedded in the Find My function, so that any Bluetooth connection device may become the possibility of Find My device.When a Bluetooth MY device is lost, the owner only needs to start the corresponding application on their smartphones or tablets to locate it, which brings more convenience and peace of mind to users.

Existing BluetoothThe Find My solution has already used Bluetooth RSSI to determine the general orientation of items.Through the use of Bluetooth channel detection, developers can now add real distance perception capabilities to Find My device, enhance user experience, and can find lost items easier and more quickly.

Bluetooth digital key solution

Bluetooth technology once again expands the role of smartphones in daily life, so that it can be used as a convenient and secure digital key.VaporCar, access control, and safe to bicycles are changing towards Bluetooth technology to achieve keyless access and provide a safer locking mechanism.

The current Bluetooth digital key solution depends on BluetoothRSSI estimates the distance between the lock and the key.Using the Bluetooth channel detection, developers can strengthen the security and user experience of the digital key solution, and ensure that only when the authorized device is within a certain distance, the lock will open.This greatly reduces the unauthorized access risk caused by the intermediate (MITM) attack.

Human -machine interface (HMI）

Apart fromIn addition to Find My and Digital Key Solutions, Bluetooth channel detection is also expected to bring benefits to many connected device solutions and change our way to interact with the world.For example, the Bluetooth human -machine interface device (HID), such as mouse, keyboard, and game controllers, can automatically switch between activity and non -activity status according to the distance between them and a smartphone, tablet or laptop.For Bluetooth human -machine interface solutions, adding Bluetooth channel detection can enhance the safety of personnel by ensuring the use of safe distances.Similarly, the Bluetooth device network for wireless lighting control can optimize its configuration by itself to improve system performance.

The main advantage of Bluetooth channel detection

It is a simple and safe choice to add fine spacing capacity to the Bluetooth connection device.

accurate

BluetoothChannel detection passes multi -channel, phase -based ranging (PBR), a highly accurate fine ranging between Bluetooth connection equipment.When the two devices are ranging, the Bluetooth channel detection can provide centimeter -level accuracy at a considerable distance to meet the needs of most applications, so thatEven the simplest connection device can use real distance perception.

Safety

With the increasing number of connected devices, the integrity of these connections is becoming more and more critical.Bluetooth channel detection is configured with powerful multi -layer security measures, covering another round -trip time (The distance of RTT) is defined from the distance, adding additional protective layers to resist complex intermediate (MITM) attacks.

Ubiquitous

Bluetooth technology has been embedded in all major consumer platform devices, such as smartphones, tablets and laptops.

With the Bluetooth channel detection, developers can now add a real distance perception to the Bluetooth connection device without designing additional radio technology.

In order to help developers use this new technology for the first time, Taoling Micro Electronics launched theSOC channel detection solution.This solution supports fast establishment of channel detection, accurately calculating the distance between devices, and can achieve +/- 0.5m ranging accuracy.In addition, it is expected that in the near future, its officially released SDK will appear.This undoubtedly presented a powerful tool for developers, which greatly accelerated the process of product development.
