Technical overview of Bluetooth Core 6.3 announced, including "improved ranging performance" and "reduced power consumption"

Bluetooth SIG has unveiled the Bluetooth Core 6.3 technical update, focusing on better ranging accuracy and lower power use.

Key changes include improved Bluetooth Channel Sounding precision, PHY-specific round-trip time support, and expanded bit-mask limits.

The spec also relaxes ACP and C/I constraints to improve wireless efficiency and make near-field detection more reliable.

These updates are expected to influence future Bluetooth device design, especially for power savings and high-precision proximity sensing.
