If you set up 802.11n Wi-Fi just right, you can get remarkable speeds from it. But, as fast as 802.11n can go, up to 300Mbps, Gigabit Wi-Fi promises to more than triple that speed. Vroom!
That’s the good news. The bad news is that it’s going to be a while before we see Gigabit Wi-Fi. It’s not that the technology isn’t available to pull this kind of speed off. If anything the problem is that there are too many technologies that Wi-Fi chip vendors can use to deliver the 1Gbps (Gigabit per second) goods.
All-together, there are three proposed Gigabyte Wi-Fi standards. These are IEEE 802.11ac, 802.11ad and Wireless Gigabit aka WiGig.
