# Bluetooth SIG High Data Throughput standard adoption > Developing situation record from CLSTR: https://clstr.news/situations/bluetooth-sig-high-data-throughput-standard-adoption > Updated: 2026-11-08T10:14:03.000Z. Sources: 18. Developments: 2. The Bluetooth Special Interest Group (SIG) has introduced the High Data Throughput (HDT) specification as an optional extension within the Bluetooth Core 7.0 standard. This update increases the maximum data transfer rate from 2 Mbps to 7.5 Mbps. The increased bandwidth is intended to enable standardized lossless audio transmission, potentially reducing industry reliance on proprietary codecs. The technology is also designed to support high-demand applications such as spatial computing, augmented reality, virtual reality, and AI-powered wearable devices. Industry representatives from companies including Samsung, Nordic Semiconductor, and Qualcomm have noted the potential for improved energy efficiency, as faster data transmission allows wireless radios to return to low-power states more quickly. Because the upgrade involves changes to the physical layer, new hardware is required to support these capabilities. ## Timeline ### 2026-11-08: Bluetooth SIG announces High Data Throughput standard The Bluetooth SIG has unveiled the High Data Throughput (HDT) standard, increasing data speeds to 7.5 Mbps to enable lossless audio and support advanced XR and AI wearable technologies. 4 sources. https://clstr.news/cluster/bluetooth-sig-announces-high-data-throughput-standard ### 2026-11-06: Bluetooth SIG adopts High Data Throughput standard for 7.5 Mbps speeds The Bluetooth SIG has adopted the High Data Throughput (HDT) standard for Bluetooth Core 7.0, boosting LE speeds to 7.5 Mbps to enable lossless audio and faster data sync for wearables. 14 sources. https://clstr.news/cluster/bluetooth-sig-adopts-high-data-throughput-standard --- Cite as: Bluetooth SIG High Data Throughput standard adoption.
