From the article:
The bad news is that the 6 GHz wireless spectrum uses shorter wavelengths. Short wavelengths are great for fast data transfers at close range, So, they're great for connecting to your Wi-Fi 7-enabled HDTV a few feet away from your router
With a range that short, you're not going to be doing much roaming around. It obviously has some use cases, but unless you need to be streaming data it doesn't make a lot of sense.
The example we are discussing in this thread is transferring data off of a high res/high performance camera. For many situations this can be done after filming is completed, in which case a cord still makes a lot more sense. Hence my joke.
For live broadcasting it could be useful, but the range still seems quite limiting.
Clearly they mean that they want the growth to be "sustainable", not the company..
