Bluetooth® High Data Throughput

Faster is just the beginning

Bluetooth® High Data Throughput (HDT) delivers faster data transfer, increased capacity, better energy efficiency, and enhanced reliability, enabling richer experiences, more sophisticated applications, and new opportunities for innovation across the Bluetooth ecosystem.

As wireless experiences expand, so do the demands

More of the experiences people, businesses, and industries rely on every day are wireless. From premium audio experiences to immersive computing, industrial systems, advanced peripherals, and emerging AI-enabled applications, wireless connectivity is being asked to support more devices, more data, and higher expectations with every new generation of products.

Keeping pace with these demands requires more than speed alone. It requires the capacity to communicate larger volumes of information with greater efficiency and reliability.

Bluetooth® High Data Throughput (HDT) was designed to meet this opportunity.

By significantly expanding the Bluetooth performance envelope, Bluetooth HDT creates the foundation to support the next generation of wireless experiences.

What is Bluetooth® High Data Throughput?

Bluetooth HDT introduces a new physical layer (PHY) that allows Bluetooth LE devices to communicate more efficiently and carry significantly more information over the Bluetooth link.

Bluetooth HDT increases the maximum supported bit rate to 7.5 Mbps, nearly four times that of the Bluetooth LE 2M PHY.

More than a speed enhancement, Bluetooth HDT enables Bluetooth devices to transfer more data, use wireless resources more efficiently, and perform more reliably across a broader range of applications and environments.

Advancing performance across the dimensions that matter most

Rather than improving a single aspect of wireless communication, Bluetooth HDT advances speed, capacity, efficiency, and reliability together, enabling Bluetooth devices to meet the growing performance demands of increasingly sophisticated applications and environments.

Faster data transfer

Move more data in less time

Bluetooth HDT delivers nearly four times the previous maximum Bluetooth bit rate, enabling devices to transfer substantially more information in the same amount of time. Faster data movement enables more responsive wireless interactions, shorter transfer times, and improved user experiences.

Increased capacity

Make room for richer experiences

Bluetooth HDT provides substantially greater capacity for wireless communication, improving spectral efficiency and creating more room for devices to exchange data within available wireless resources. This additional headroom helps Bluetooth devices support today’s more demanding applications as well as tomorrow’s innovations.

Better energy efficiency

Do more with available power

Bluetooth HDT moves more data in less time, allowing the radio to spend less time actively transmitting and more time in lower-power states. This helps devices deliver higher levels of performance while using energy more efficiently.

Enhanced reliability

Deliver more consistent performance

Bluetooth HDT improves communication robustness and resilience, helping devices maintain more consistent wireless performance across a broader and more demanding range of operating environments.

Opening new possibilities

Bluetooth® High Data Throughput (HDT) unlocks a new level of wireless performance, enabling richer experiences and more sophisticated applications across a growing range of use cases.

Premium wireless audio

The first flagship application for Bluetooth HDT will be premium wireless audio. Bluetooth HDT provides the capacity, efficiency, and wireless performance needed to support high-resolution and lossless audio, while creating new opportunities for surround sound, spatial audio, and other elevated audio experiences across the Bluetooth ecosystem.

Immersive and spatial computing

As extended reality (XR), spatial computing, and other immersive applications continue to evolve, Bluetooth HDT enables more responsive experiences and increasingly complex device interactions, introducing new possibilities for innovation across this rapidly expanding application space.

AI-enabled devices

With more data being generated, processed, and exchanged at the edge, Bluetooth HDT provides the foundation for increasingly intelligent, context-aware, and adaptive AI-enabled experiences.

Commercial and industrial solutions

Bluetooth HDT delivers the capacity and reliability needed to enable more advanced automation, monitoring, and operational systems across commercial and industrial environments.

Everyday connected devices

From wearables and health and fitness devices to smart home products and peripherals, Bluetooth HDT enables everyday data exchanges, including syncing information, transferring files, and receiving firmware updates, to happen faster, reducing wait times and keeping data transfer from getting in the way of the connected experience.
