If you're anything like me, your iPhone probably spends much more time on Wi-Fi than it does using mobile data – so the better the Wi-Fi, the better your iPhone experience. Like the rest of the current range, my iPhone 14 Pro has Wi-Fi 6. That's pretty fast, but the Wi-Fi in the new 14-inch and 16-inch M2 MacBook Pros and Mac minis is better still – and that's the version tipped for the iPhone 15.
According to a research note by Barclays analysts, as shared by MacRumors (opens in new tab), Wi-Fi 6E is coming to the iPhone 15. However, it's currently unclear whether that means the entire iPhone 15 range or just the Pro and Ultra models.
Why you'll want Wi-Fi 6E in your iPhone 15
The big difference between Wi-Fi 6 and Wi-Fi 6E is that the latter uses an extra frequency band: the E stands for Extended.
Wi-Fi 6 is dual band on the 2.4GHz and 5GHz bands, but Wi-Fi 6E also uses the considerably less congested 6GHz bands. Those frequencies aren't used by any previous Wi-Fi standards, so for the time being at least the rest of your and your neighbours' Wi-Fi devices won't be using that part of the radio spectrum.
Provided your router also supports it, that means faster speeds, less interference and less lag: your iPhone will have an uncluttered, exclusive connection that isn't fighting for bandwidth with your smart home devices or your Smart TV. And as ever it's backwards compatible so you'll be able to use your iPhone with any Wi-Fi access point, irrespective of its Wi-Fi version.
I'm hoping that Apple does the same with Wi-Fi 6E as it did with Wi-Fi 6 and brings it to every iPhone, not just the most expensive ones. But given Apple is reportedly planning to limit its newest chipsets to the Pro/Ultra models in order to differentiate them from the standard models, it's possible that lesser iPhones might not get the tech until the iPhone 16.
