All iPhone 16 models now support Wi-Fi 7 and come with 2×2 MIMO 2-Spatial Stream radio configuration. But Wi-Fi 7 doesn’t make support of 6 GHz band mandatory. So technically there could be Wi-Fi 7 clients that only support 2.4 GHz and 5 GHz.
Do iPhones 16 support all three 2.4 GHz, 5 GHz and 6 GHz Wi-Fi bands?
I tested a standard non-Pro iPhone 16 model.
It indeed supports all three Wi-Fi bands. Here is a proof of iPhone 16 connected to a Wi-Fi 7 access point using 6 GHz channel 69.
Using the My Wi-Fi Apple Shortcut we can look into another level of detail. In this case the iPhone is using the 802.11be Wi-Fi 7 standard to communicate with the access point.
Association Request
As the iPhone associates to the AP, it announces no support for 320 MHz channel width.
