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 to let 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 in earlier versions. If you have an Apple Watch that supports cellular connectivity and pay for the service, you can perform many of these features — making calls, sending texts, and accessing online music — without having an iPhone nearby.
