New Bluetooth 6.0 features include device tracking, energy efficiency, and data transmission improvements, according to the Bluetooth Special Interest Group. The latest version of Bluetooth will be available soon on smartphones, computers, and other consumer electronics.
Version 6.0 of the Bluetooth Core Specification, also known as Bluetooth 6.0, contains six significant upgrades. Bluetooth-enabled devices can now measure the distance between themselves more accurately thanks to improved distance awareness.
It helps users recover their misplaced or stolen gadgets by improving the accuracy of features like ‘Find My Device’.
Bluetooth Channel Sounding
Bluetooth 6.0 introduces Bluetooth Channel Sounding. For accurate positioning, it uses Angle of Arrival (AoA) and Angle of Direction (AoD) signal transmission techniques.
Bluetooth signals were previously transmitted using typical radio emission techniques, which made it difficult to track a device accurately. It also reduces path loss, so even over long distances, the signals will remain strong.
With Bluetooth Channel Sounding, Bluetooth Trackers and Find My Device on Android, iOS, and other operating systems will perform much more accurately. Due to the regulated transmission of signals, the technology also consumes less power overall.
Decision-based Advertising Filtering
The Bluetooth Low Energy Extended Advertising feature transmits data via primary and secondary radio channels. By scanning a packet’s contents, a device can decide whether primary or secondary channels should be used for transmission.
As a result, Bluetooth devices will be able to communicate more quickly between two gadgets, improving scanning efficiency. OEMs may differ in their implementation, however.
Monitoring Advertisers
It is now possible to filter out duplicate packets in Bluetooth 6.0. The Bluetooth LE controller receives only one advertising packet from each device. Devices can then determine when a specific gadget is no longer connected to Bluetooth.
ISOAL Enhancement
With ISOAL, larger data frames are transferred in smaller link-layer packets. Data transmission accuracy is improved, but latency is also increased to some extent. A new framing mode in Bluetooth 6.0 enhances ISOAL. While maintaining all the core advantages of ISOAL, it reduces the overall latency.
LL Extended Feature Set
Devices that support Bluetooth 6.0 can exchange information about their link-layer features seamlessly. It helps devices communicate only with technologies that are supported on both ends. With the increase in Bluetooth LE devices, the new LL Extended Feature Set brings new versatility for devices to communicate while consuming less energy.
Frame Space Update
With Bluetooth 6.0, packet transmissions are separated by a variable constant time value. Devices can now use different time intervals for different types of data. Therefore, devices will not have to keep the communication link active if the bandwidth requirement is low. As a result, Bluetooth wireless transmission is more efficient.
A wide range of wireless audio products will be supported by Bluetooth 6.0, including smartphones, TWS earbuds, headphones, laptops, and computers. With backwards compatibility, older versions of Bluetooth will be able to pair and function with it.
