The Bluetooth Special Interest Group has adopted Bluetooth High Data Throughput (HDT) as an optional feature in Bluetooth Core 7.0, raising Bluetooth Low Energy’s maximum supported bit rate to 7.5 Mbps from 2 Mbps. The Bluetooth SIG announcement describes HDT as a new physical layer designed to move more data while improving efficiency and reliability.
The group says the higher throughput can shorten transfers and synchronization times while allowing radios to spend less time transmitting, potentially reducing energy use. HDT remains part of the Bluetooth LE architecture and is an optional Core 7.0 capability.
Standardized premium wireless audio is expected to be the first flagship use in 2027. The Bluetooth SIG says HDT will support lossless and high-resolution audio, along with advances in multichannel surround sound and spatial audio.
