Читать книгу Apple Watch For Dummies - Marc Saltzman - Страница 44

Bluetooth makes a local wireless connection between two or more devices. Just as your wireless headset is paired with your smartphone so you can make hands-free calls, Apple Watch wirelessly communicates with a nearby iPhone. This lets you see texts on your watch, receive phone calls, control your music on your phone, and more. Bluetooth 5.0 works with devices up to 800 feet away (about 240 meters), which is significantly farther than earlier versions. If you have an Apple Watch that supports cellular connectivity and pay for the service, you can perform many of these features — calls, texts, and accessing online music — without a nearby iPhone.
