Bluetooth SIG Adopts HDT Standard, Boosting BLE Transfer Speed by ~4x to 7.5 Mbps
Bluetooth SIG has adopted the new HDT standard, raising maximum BLE data transfer rates to 7.5 Mbps, with first applications expected in 2027.
The Bluetooth Special Interest Group (Bluetooth SIG) announced on November 4, 2026, the adoption of a new standard named "Bluetooth HDT (High Data Throughput)," which increases the maximum data transfer rate of Bluetooth Low Energy (BLE) to 7.5 megabits per second (Mbps), approximately four times the traditional standard.
This performance leap is achieved by introducing a new physical layer modulation scheme with enhanced robustness. Beyond speed, HDT improves spectral efficiency to expand communication capacity, while shorter transmission times contribute to better energy efficiency and increased reliability and resilience.
According to the roadmap, the first application based on Bluetooth HDT will launch in 2027, featuring a new audio codec called "HRC" that supports lossless audio transmission at 96 kHz sampling rate and 24-bit depth. Detailed specifications are expected to be revealed at CES 2027 in Las Vegas. The standard is also positioned as key infrastructure support for future applications in extended reality (XR), AI devices, commercial and industrial solutions, and wearables.
