New Delhi, Nov 5: The Bluetooth Special Interest Group (SIG), the global organisation responsible for developing and overseeing Bluetooth standards, has adopted a new technology called High Data Throughput (HDT), which increases the maximum data transfer speed supported by Bluetooth Low Energy to 7.5 megabits per second (Mbps), nearly four times the previous limit of 2 Mbps.
The technology is part of the Bluetooth Core 7.0 specification and is designed to help compatible devices exchange larger amounts of data in less time. It is expected to open up new possibilities in wireless audio, wearables, smart glasses and other connected products.
Bluetooth is widely used to connect devices such as wireless earbuds, headphones, smartwatches and speakers to smartphones. However, limitations in data transfer speeds can restrict applications that require higher bandwidth. The new HDT feature aims to overcome this challenge by allowing compatible Bluetooth Low Energy devices to transfer information at significantly higher rates.
Bluetooth HDT supports five data rates — 2 Mbps, 3 Mbps, 4 Mbps, 6 Mbps and 7.5 Mbps. Devices can operate at different speeds depending on their requirements and connection conditions.
According to Bluetooth SIG, the technology is designed to improve data transfer speeds, increase the volume of information devices can exchange, enhance energy efficiency and provide more reliable connections.
Higher data rates could reduce the time required for synchronising information between devices, transferring files and installing software updates. The technology is also expected to improve power efficiency, as devices may complete data transfers faster and spend more time in low-power states.
One of the major applications expected to benefit from Bluetooth HDT is premium wireless audio. Bluetooth SIG expects standardised premium wireless audio products using the technology to arrive in 2027.
The additional bandwidth is intended to support lossless and high-resolution audio transmission, multi-channel surround sound and spatial audio. This could allow manufacturers to develop wireless audio products with greater data requirements within a standardised Bluetooth framework.
Other potential applications include smartwatches capable of synchronising large volumes of fitness data more quickly, smart glasses transferring information for artificial intelligence processing, and smart home devices completing firmware updates faster.
Bluetooth HDT is an optional feature under the recently adopted Bluetooth Core 7.0 specification. Device manufacturers will therefore need to incorporate the necessary hardware support to enable the higher data rates.
The adoption of the specification does not mean existing Bluetooth devices will automatically receive the upgrade. Its availability will depend on manufacturers integrating the technology into future compatible products.
With the first major application in standardised premium wireless audio expected in 2027, Bluetooth HDT could mark a significant development in the evolution of wireless connectivity.
