Barclays analysts Blayne Curtis and Tom O'Malley recently shared a research note indicating that the iPhone 15 will likely have Wi-Fi 6E. It is unclear, however, whether this feature will be available for all models or only the Pro models. Apple has so far added Wi-Fi 6E to the 11-inch and 12.9-inch iPad Pro, 14-inch and 16-inch MacBook Pro, and Mac mini models, although iPhones remain limited to Wi-Fi 6.

Wi-Fi 6E utilizes the 2.4GHz and 5GHz bands, in addition to the 6GHz band, allowing for faster wireless speeds, lower latency, and less signal interference. This technology allows for faster download and upload speeds, a larger capacity for more devices to connect to a single router, and better performance in areas with high levels of signal interference. Additionally, it is more reliable than Wi-Fi 5, as it can handle more data, and is suitable for activities that require high bandwidth, such as streaming high-definition video or gaming. Other than providing enhanced wireless performance, Wi-Fi 6E also offers improved device battery life, as the technology is optimized to reduce power consumption. However, to experience these benefits, the device must be connected to a Wi-Fi 6E router. Companies such as TP-Link, Asus, and Netgear offer Wi-Fi 6E routers.

Though there were rumors that the iPhone 13 and iPhone 14 would incorporate Wi-Fi 6E, this feature did not appear. But now that Apple has launched Wi-Fi 6E support in its more recent devices, it seems much more likely that the iPhone 15 will include this technology.

Apple is anticipated to launch the iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max in September. Reports suggest that all four models may feature the Dynamic Island and a USB-C port, while the Pro models may contain Apple's A17 Bionic chip, a titanium frame, solid-state volume and power buttons, and more. With the inclusion of Wi-Fi 6E in the iPhone 15, users should expect faster and more reliable wireless performance than before, as well as improved device battery life.

Apple has a support document outlining more information about Wi-Fi 6E.
