802.11ac Wi-Fi Will Emerge Gradually

Peter Judge:

The latest Wi-Fi standard, 802.11ac, will be adopted gradually, but favour distributed architectures that do not have central controllers, according to Wi-Fi network vendor Aerohive.

The new standard is advertised as enabling “Gigabit” throughput over Wi-Fi, and unlike earlier throughput promises, this one is not too far from the truth, says the company’s product manager, Matthew Gast. It allows wider radio channels (160MHz rather than 40MHz), and more parallel spatial streams (eight instead of four) between the sender and receiver.

“802.11ac won’t revolutionise the way we build networks, but any time you do 25 percent better than you did yesterday, that’s a gain that is worth talking about,” says Gast.

This is very similar to what I had in mind when I wrote this.
