Apple Innovates Group Audio Chats Without Cellular or WiFi Networks

Apple is pioneering a new technology that enables group audio chats using only an iPhone and AirPods, eliminating the need for WiFi or cellular service.

This innovative feature would allow immediate communication among people in close proximity, much like the Walkie-Talkie feature on the Apple Watch, but for groups.

Unlike the existing Walkie-Talkie feature, this new system bypasses Apple's cloud servers, enhancing reliability. Users can engage in group conversations simultaneously without internet connectivity.

Apple's recent patent application reveals a direct device-to-device communication system, facilitating seamless person-to-person interactions. This technology will enable users to effortlessly start group audio chats using just their iPhones.

The functionality will resemble AirDrop, allowing one-to-many connections for group conversations. For instance, attendees at a crowded festival could communicate easily to coordinate meetups. The iPhone would display proximity using the same technology that guides users to their AirTags.

Apple's Ultra Wide Band (UWB) technology, already embedded in iPhones and Apple Watches, will power this feature. UWB works like echolocation, sending radio waves and measuring return signals to determine the location of devices.

This innovation could also be invaluable in emergency situations where cell networks are overloaded. Teams could coordinate without needing physical walkie-talkies or specific frequencies.

The patent describes an interface displaying nearby people in a proximity circle. Users within the main circle are closest, while those farther away are shown in outer circles. Tapping on a name adds someone to the conversation, allowing for dynamic group formation as people come into range.

This technology could extend beyond iPhones and AirPods to future devices like the Apple Vision Pro or rumored Apple glasses, enhancing point-to-point communications.

The patent, credited to Esge B. Andersen and Cedrik Bacon, was originally filed in 2022.
