Apple today released a new developer tool that is designed to force devices running iOS 15 and iPadOS 15 to priortize a 5G connection over a WiFi connection when on an insecure WiFi network or when a WiFi connection is slow.
5G devices running iOS 15 and iPadOS 15 can automatically prioritize connecting via 5G instead of WiFi when the performance of WiFi networks you visit occasionally is slow, or when you are connected to captive or insecure WiFi networks. Install the 5G Preferred Over Wi-Fi profile ("profile") on devices running iOS 15 and iPadOS 15 Beta 4 or greater to greatly increase the likelihood of seeing 5G preferred over Wi-Fi connections and to ensure your networking path logic is optimized for situations where 5G will be preferred. For more information, see https://developer.apple.com/5g/.Apple says that developers who want to prioritize 5G usage on their devices can do so by running the fourth beta of iOS 15/iPadOS 15 or later and downloading the 5G Preferred Over WiFi Pro
