Google's Pixel Watch 3, updated with Wear OS 5.1, features Channel Sounding, a Bluetooth 6.0 technology improving location accuracy of connected devices. Unlike UWB, Channel Sounding leverages existing Bluetooth hardware, offering centimeter-level accuracy. However, widespread implementation requires more devices and software updates to support Bluetooth 6.0, delaying its current functionality.
