Re: What's the use case for 100 Gbps wireless?
Sure its faster than any one PC will need, but if you're looking at networking, you want to share resources.
Cross-rack traffic has been mentioned. There are security applications where you might want wireless, but you want to confine it geographically. You might want to have some high-speed networking in your bedroom which doesn't involve irradiating your head while you sleep. I might not want to turn it off in the rest of the house, but a simple cover (or sweaty t-shirt) can close it down locally. The 100G engineering might pay-off with smaller capacity consumer networking.
