Bluetooth SIG has announced the Bluetooth HDT technology with a maximum transmission speed of 7.5 Mb per second. This connection standard aims to transmit uncompressed high-quality audio wirelessly.

Key Developments and Technical Context

Bluetooth SIG introduced Bluetooth High Data Throughput technology with a maximum transmission speed of 7.5 Mb per second, roughly four times the current Bluetooth LE 2M standard.

The new connection standard can handle CD-quality audio from 0.8 to 1.4 Mb per second, the 24-bit over 48 kHz standard at 2.3 Mb per second, and the 24-bit over 96 kHz standard at 4.6 Mb per second.

Technical documents indicate that high-speed configurations like HDT6 or HDT7.5 are optional features for manufacturers rather than mandatory on all devices supporting the Bluetooth 7.0 standard.

Strategic Analysis and Industry Implications

The 7.5 Mb per second bandwidth opens up the possibility of eliminating traditional audio compression algorithms for the majority of high-quality music formats today.

The adoption of high-speed configurations depends on individual hardware manufacturers, meaning not every new device will automatically support it.

Outlook and Key Factors to Watch

The specific timeline for major audio brands to commercialize devices integrated with the Bluetooth HDT standard has not yet been determined.
