2020 iPhones May Support New Short Range Wi-Fi Standard
802.11ay is the follow-up of IEEE 802.11ad, quadrupling the bandwidth and adding up to 4 streams of multiple transmission/reception. The new Wi-Fi spec, which uses the 60GHz spectrum, is still in the draft phase but is expected to be finalized by the end of 2020.
The translated report is quite difficult to decipher, but the blog calls the wireless standard "ultra-short range," which suggests it could be used to communicate between iPhones (i.e. AirDrop) and perhaps other Apple devices in close proximity.
Interestingly, a 2018 report claimed that Apple has been working on an AR/VR headset that would be untethered from either a computer or a smartphone and instead connect to a "dedicated box" using the 802.11ay wireless standard. The box was said to be powered by a custom 5-nanometer Apple processor similar to the custom chips that Apple will use in future Macs.
Connecting the two rumors is pure speculation at this point, but it's interesting to conceive of different scenarios where Apple uses the new Wi-Fi standard to enable next-generation wireless AR/VR experiences.
In November, Gurman said Apple is working on "a range of augmented and virtual-reality devices" based around a new 3D sensor system, which will arrive first on a new iPad Pro slated for release in the first half of 2020, and followed by Apple's new iPhones later in the year.
Moving beyond existing devices, Apple is said to be targeting 2021 or 2022 for the release of a combination VR and AR headset focused on "gaming, watching video and virtual meetings."
