Bluetooth SIG Releases Core 7.0 with High Data Throughput

The Bluetooth Special Interest Group adopted the Bluetooth Core 7.0 specification on November 4, 2026, introducing High Data Throughput (HDT). This optional physical layer for Bluetooth Low Energy increases the maximum supported bit rate to 7.5 Mbps, nearly four times the 2 Mbps limit of the previous LE 2M PHY.

HDT utilizes a new radio architecture requiring coherent detection, meaning existing devices cannot be upgraded via firmware and require new silicon hardware. The technology improves spectral and energy efficiency while increasing communication reliability. The primary application will be standardized premium lossless and high-resolution wireless audio, including multi-channel spatial audio, removing the industry's reliance on proprietary codecs.

Beyond audio, the standard supports immersive spatial computing, AI-enabled wearables, and industrial automation. Potential use cases include smartwatches that sync sensor-rich training data in seconds and smart glasses that offload data for AI processing. Ceva, Inc. has already begun licensing Bluetooth HDT IP to over ten customers, including Actions Technology, to accelerate commercial adoption.

While the specification is now official, the Bluetooth SIG expects to release a standardized premium wireless audio profile in 2027. Certified consumer products are anticipated to reach store shelves in late 2027 or 2028, with widespread adoption likely taking several years.
