Is 6E ready for primetime? I mean, from what I understand, you don't get any benefit from it unless you are in the same room as your router due to the shorter wavelengths.
I'm sure everyone's situation is different but I just did a test. Next to the router with the iphone 15 Pro Max on 6e I got 1566Mbps down and 1597Mbps up. It's a 5Gbps internet. In my bedroom which has a large walk pantry between it and my den where my router is, so two walls to pass through I got 1536Mbps down and 893Mbps. I did multiple tests at both and the results were consistent. So looks like it does effect the upload speeds.
I'm not going to bother switching to a none 6e wifi but I did do these tests previously and every 6e device I have went from 800-900Mbps to above 1400Mbps on 6e.
I can tell you it that it absolutely makes a difference if you are watching 4k-8k 120fps 180 deg videos. Less buffering issues and significantly faster 5 second jump ahead presses when doing it multiple times in rapid fire.
As more people have VR headsets the quality of these videos are going to go up requiring more wifi bandwidth.
I was leaning towards a not strong maybe on buying the new Vision Pro on day one. I can afford it if I want it but it is still a significant purchase for me so not having 6e will probably lean me more towards waiting for the next Vision Pro 2.
The other factor affecting my decision was the lack of multiple desktop screens from a paired Macbook Pro. I was hoping to use it as a monitor replacement where you can have 2-3 screens floating in front of you. It works with Meta Pro and absolutely requires 6e. Without 6e there is tons of latency from the displays and mouse movement when you have more than one screen which maybe the reason Apple is only supporting 1 screen on their headset.
However honestly the technology isn't great yet on the Meta Pro and is more novelty especially when I tried it at my office where we didn't have 6e. I was really hoping it would be better with the Vision Pro where I use it a full 8 hours a day for work. And who knows maybe will be better if you just compare a single desktop on Meta Pro vs Vision Pro.
