Google quietly introduced precise Bluetooth tracking on the Pixel Watch 3

With the Wear OS 5.1 update that was released last March, Google quietly introduced a new feature called Channel Sounding for the Pixel Watch 3 that could improve the accuracy of pinpointing the location of other devices using its existing Bluetooth hardware. But while Channel Sounding is now supported by the smartwatch, it’s not yet in use because the wearable is one of the first Android devices to implement it, according to Android Authority, and you need multiple devices supporting the feature for it to work.
