New devices, such as Pixel 10 already support channel sounding.
Basically it's alternative to UWB.
One phone sends signals on multiple frequencies, another receives them. Obviously devices should be connected via BT.
Also tracking people already works with BT/WiFi RSSI (signal strength). Channel Sounding works better because it works even when the signal line of sight is obstructed, for ex. headphones lost under pillow.
How do they compare in actual use? I have a Pixel 6a connected to $40USD bone conducting headphones and the range and punch-through are incredible; the phone is sitting in the living room playing music and I can almost make it to my mailbox at the end of the block (about 3 houses away) before it starts to degrade or cut out.
Do these alternatives compare with just how well UWB serves regular, normal daily activity like this? Because to me, what I have is absolutely excellent in use with daily routine.
