A new Bluetooth milestone, Bluetooth® High Data Throughput delivers a higher level of wireless performance
Bluetooth® technology is entering its next major stage of evolution. The Bluetooth Special Interest Group (SIG) has adopted Bluetooth® High Data Throughput (HDT), a new capability that introduces faster data transfer, increased capacity, better energy efficiency, and enhanced reliability. By significantly expanding the Bluetooth performance envelope, Bluetooth HDT establishes the foundation for the next generation of wireless experiences and continued innovation across the global Bluetooth ecosystem.
A new level of wireless performance
At the center of Bluetooth® HDT is a new physical layer, or PHY, with robust modulation schemes that allow 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.
Keeping pace with the growing demands of wireless connectivity requires more than speed alone. Devices must also be able to communicate larger volumes of information with greater efficiency and reliability. Bluetooth HDT addresses these requirements across four interconnected dimensions: faster data transfer, increased capacity, better energy efficiency, and enhanced reliability.
Faster data transfer
Bluetooth HDT delivers nearly four times the previous maximum Bluetooth throughput, enabling devices to transfer substantially more information in the same amount of time. As applications become increasingly data-intensive, this faster movement of data can support more responsive wireless interactions, shorter transfer times, faster synchronization and file movement, and improved user experiences.
Increased capacity
Through improved spectral efficiency, Bluetooth HDT creates more room for devices to exchange data within available wireless resources. This increased capacity provides enhanced support for increasingly sophisticated and data-intensive applications.
Better energy efficiency
Moving more data in less time allows the radio to spend less time actively transmitting and more time in lower-power states. As a result, devices can deliver higher levels of performance while using energy more efficiently.
Enhanced reliability
Bluetooth HDT also improves communication robustness and resilience. These improvements help devices maintain more consistent wireless performance across a broader and more demanding range of operating environments.
“The significance of Bluetooth® High Data Throughput goes well beyond speed,” said Joonsuk Kim, executive vice president and head of S.LSI CP development at Samsung Electronics. “By advancing data throughput, capacity, energy efficiency, and reliability together, Bluetooth® HDT gives developers and product makers a stronger foundation for building more capable products and richer wireless experiences. Together, these advancements enable more sophisticated applications, new product opportunities, and continued Bluetooth ecosystem growth.”

Bringing premium wireless audio experiences to life
Expected to be released in 2027, the first flagship application for Bluetooth® High Data Throughput will be standardized premium wireless audio. As demand for higher-quality wireless listening experiences increases, Bluetooth HDT provides the capacity, efficiency, and wireless performance needed to deliver standardized lossless and high-resolution audio.
The technology will also support advances in multi-channel surround sound, spatial audio, and other elevated Bluetooth audio experiences.
Supporting the next generation of Bluetooth® applications
The same performance improvements that enable richer audio experiences can benefit a growing range of Bluetooth applications. Across immersive computing, AI-enabled devices, commercial and industrial systems, and everyday connected products, Bluetooth® HDT provides a stronger foundation for increasingly sophisticated wireless experiences.
Immersive and spatial computing
As extended reality, spatial computing, and other immersive applications continue to evolve, Bluetooth HDT can enable more responsive experiences and increasingly complex interactions between devices. These capabilities introduce new possibilities for innovation across this rapidly expanding application space.
AI-enabled devices
More data is being generated, processed, and exchanged at the edge. Bluetooth HDT provides the foundation needed to support increasingly intelligent, context-aware, and adaptive AI-enabled experiences.
Commercial and industrial solutions
Reliance on wireless communication continues to grow across commercial and industrial environments. Bluetooth HDT delivers the capacity and reliability needed to enable more advanced automation, monitoring, and operational systems.
Everyday connected devices
Billions of wearables, health and fitness devices, smart home products, peripherals, and other connected products rely on Bluetooth technology. Bluetooth HDT enables common data exchanges to happen faster, reducing wait times and helping prevent data-transfer delays from interfering with the connected experience.
“By making it significantly faster to move large amounts of data, Bluetooth® High Data Throughput creates new possibilities for Bluetooth applications,” said Øyvind Strøm, executive vice president of the short-range business unit at Nordic Semiconductor. “Imagine a smartwatch that syncs hours’ worth of sensor-rich training data to your phone in seconds, smart glasses that deliver richer AI experiences by offloading data for processing, or a smart home product that completes a firmware update with virtually no user-visible downtime. Bluetooth HDT paves the way for more sophisticated, data-intensive Bluetooth applications, and we can’t wait to see what our customers and the Bluetooth community build next.”
