Google Pixel Watch 3 becomes first Android watch with channel sounding Bluetooth tracking
Google's Pixel Watch 3 is quietly raising the bar for Android smartwatches. Released with the Wear OS 5.1 update in March 2024, it's the first watch on the platform to include Channel Sounding, a Bluetooth feature that measures the exact time it takes a signal to travel between devices. This approach delivers far more precise tracking than older Bluetooth methods that only guess distance based on signal strength. The hardware already supports it, but the feature still depends on more devices adopting the same technology before it becomes part of daily use. Channel Sounding is a Bluetooth technology designed to calculate distance between two devices measuring how long it takes a signal to travel back and forth between. Unlike older Bluetooth methods that only estimate distance based on signal strength (which can be unreliable), Channel Sounding uses precise timing data. This allows devices like the Pixel Watch 3 to show correct information about how close you are to something you're trying to find. For example, if you drop a set of earbuds behind your sofa, Channel Sounding can show you precisely how far away they are, instead of giving you a vague indication that they are in the same room. It provides the exact location, helping you find small devices like earbuds in minutes. Find My Device feature shows you where your lost item was last seen on a map, like in your office, in your car or somewhere inside your home. It gives you the general area but doesn't pinpoint the exact spot within that space. Channel Sounding helps you when you are near your device. If you're standing in your living room, it can guide you step by step and tell you the earbuds are one metre away, like under the sofa cushion. So, in short, the Find my device feature tells you which room to search and Channel Sounding guides you to the specific spot in the room. This combination of features could make finding lost items much easier for people who often misplace small things at home or work. While Find My Device gives you a good idea of where to start looking, Channel Sounding can help you finish the search quickly by pointing out the exact distance. Right now, even though Google's Pixel Watch 3 has the technology ready, you can't fully use this feature yet. The main reason is that Channel Sounding requires other devices that can communicate with your smartwatch using the same Bluetooth technology. These could be future smartphones, trackers, or other accessories that haven't come out yet. Google has not shared a clear timeline for when this technology will be ready to use in everyday situations, but it has confirmed that more products will add support over time. However, including Channel Sounding now means Google's Pixel Watch 3 is prepared for the future. As more accessories and Android devices start supporting this system, people will gradually see the benefits of faster, more accurate tracking. In the coming months, anyone interested in this technology should keep an eye on announcements about new accessories and updates that will help enable precise tracking. For now, Pixel Watch 3 owners will need to wait for compatible devices to be released before they can try Channel Sounding in real world scenarios. The Pixel Watch 3 already has the tech to help you find lost things more easily. You can't use it yet, but it shows the direction Android is going. As more devices add Channel Sounding, tracking will get more accurate and helpful for everyone.

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. The Bluetooth Special Interest Group (SIG) announced the latest iteration of its wireless communication protocol in September 2024, and one of Bluetooth 6.0's most interesting upgrades has nothing to do with wireless headphones. Most Bluetooth-based trackers rely on the signal strength between two connected devices to estimate their distance, but it's frequently unreliable due to obstacles or interference. Channel Sounding instead measures the time it takes to send multiple radio signals at different frequencies between two connected devices. According to Bluetooth SIG, that approach allows for 'centimeter-level accuracy,' as well as directional awareness. Pinpointing the exact location of a tracking device like an Apple AirTag using an iPhone is easy thanks to their use of Ultra-Wideband (UWB) hardware. The wireless UWB protocol provides more accurate spatial awareness between devices, allowing apps like Apple's Find My to determine the exact distance to a tracker like an AirTag and provide directional arrows guiding you to its location. But UWB requires its own radio and antenna, which increases the hardware costs of a device. The advantage of Channel Sounding is that it uses the Bluetooth hardware that's now common in nearly every smartphone, smartwatch, and set of wireless headphones. Devices will need Bluetooth hardware that supports the new 6.0 protocol, but given the Pixel Watch 3 is nearly 10 months old at this point, there are plenty of devices available that are already compatible. We just need more companies to release software updates that add support for Bluetooth 6.0 so we can actually start taking advantage of these new features.
