IT House News on September 17th, on September 8th, Apple held a new product launch conference and officially released the iPhone 14 / Pro series of mobile phones. The model starts at 5,999 yuan. In addition to the new Smart Island design, Apple has added another new feature to the iPhone 14 Pro series.
According to the discussion of netizens on the “Communication Home” forum, the Apple iPhone 14 Pro series has added the VoNR (Ultra High Definition Audio and Video Call) function, and users can turn on the independent 5G voice in the voice and data interface in the cellular data option. It is worth mentioning that this feature is only available on the iPhone 14 Pro series models, and is not available on the iPhone 14 series and iPhone 13 / Pro series phones.
According to public information, the full name of VoNR is Voice over New Radio, that is, the voice over the new air interface, which is the target voice solution of the 5G network. Before the application of VoNR technology, making a voice call will make the mobile phone network fall back from 5G to 4G, but VoNR technology supports 5G data and voice concurrency.
Specifically, the use of VoNR technology can not only shorten the connection establishment time of telephone calls, but also greatly improve the connection success rate while reducing possible interruptions during the call. In addition, it can maintain a stable and high-speed 5G data connection during calls, so that the gaming and video experience will not be affected.
IT House has learned that from April to May this year, China Mobile, China Unicom, and China Telecom have successively announced that they will support VoNR-related functions based on 5G SA networks, and will open related services in major cities across the country.
