Wifi 7 issues on iPhone 16 Pro & Pro Max

Hi there,

Does anyone at apple  or communities here know what is actually happening to iPhone 16 Pro & Pro Max where it seems like its Wifi 7 speeds are only capped in between 1.5Gbps - 1.7Gbps?

Is it true that apple only allow all iPhone 16 Pro & Pro Max to run on 160 Mhz instead of the full 320Mhz capacity of wifi 7?

if yes, does apple has any plans to provide any software/firmware updates for all iPhone 16 models to support the full 320Mhz spectrum in the nearest future?

to be honest, I’m eagerly getting the new iPhone 16 is just because to test out the wifi 7 compatibility and performance but turn out it was major disappointment to me anyway. :(

iPhone 16 Pro Max, iOS 18

This is a user-to-user forum, no one here can answer your questions about Apple’s implementation of Wi-Fi 7.

UPDATE: Here are Apple’s Wi-Fi specs→Wi-Fi specifications for Apple devices - Apple Support

The iPhone 16 and 16 Pro support 160 MHz bandwidth, not 320 MHz. As bandwidth is a hardware function, it is unlikely that there will be a software update for 320 MHz bandwidth.

That iPhone 16 Pro Max teardown webpage got taken down by the moderator.

Alright, so my final update here is this, after further digging. The iPhone 16 Pro Max has the USI Wi-Fi & Bluetooth

Module 339S01463 which either uses the Broadcom BCM4389 (Wi-Fi 6E max. channel bandwidth 160MHz) or the BCM4398 (Wi-Fi 6E max. channel bandwidth 320MHz) chip. That's it. Uncertainty once again!

Moving forward, I will dig deeper to know more about the specs I care about when buying an Apple device.

I'm moving to my first self-owned house in few months & have been planning on setting up a nice lil home network with WiFi 7 AP for my iPhone 16PM + future devices, so pretty disappointing to see the WiFi spec capped in this way.

However I'm planning on getting a 1Gb up & down plan, and as the speed cap apparently is around 1.5Gb, I should still be able to get (close enough to) those 1Gb WiFi speeds right? Even with just 160 MHz instead of 320 MHz channel bandwidth?

Or will the WiFi speed always be a lower percentage of the max set by your ISP, so a higher plan will be needed to reach 1Gb on the phone, especially with this 160 MHz cap?

Why would they cap it? Just so they can say it’s bigger, better and charge more even though it’s really not an upgrade?
