Wifi 15 gigabytes per second — Researchers demo invention
(www.tomshardware.com)
This is a most excellent place for technology news and articles.
It's definitely a niche product. Most people don't even need gig speeds.
They hint at their goals by mentioning fiber in a datacenter, where they are now getting to 400/800gb speeds, so in the ballpark of this demo, but this would be a shared medium instead of a switched network, so it's DOA there as well.
I don't think this is a product yet .. more like a technical solution for building a power efficient modulation at high frequency. Gigabit speeds are great but the band they are sitting in is mostly useless unless you have line of sight.
