802.11ac WiFi Decision Time

Gigabit WiFi has arrived, but its real-world performance may not meet lofty expectations. Find out why, and how and when to think about upgrading.

With the 802.11ac standard, Wi-Fi has finally matured to the point that it can meet or beat the user experience of Ethernet, making wireless the LAN of choice. Wireless LAN products that use the very high-throughput protocols of 802.11ac to reach gigabit speeds have been gaining ground since the Wi-Fi Alliance launched its Wi-Fi Certified ac program last June. The December publication of the final standard will throw open the floodgates.

In a series of articles, I'll examine the 11ac standard, its benefits, how it's incorporated into products, and enterprise 11ac adoption strategies.

The 802.11ac standard builds on lessons learned from 802.11n, tweaking technologies to get more from multiple input, multiple output (MIMO) wireless devices operating in the 5-GHz radio frequency (RF) band. The major enhancements in the 11ac standard include cleaner airspace, wider channels, tighter modulation, supporting more streams, standard beamforming, and supporting more users.

Re: Gig WiFi adoption
Well, we've also had the usual roll of "pre-standard" 802.11ac out there too, which brings back many uncomfortable memories of 802.11n!

 

I'm looking forward to gigabit wifi. A couple of years back, I didn't see the point outside an enteprise environment, but having thought about it some more, the benefits of having low utilization on a faster network rather than high utilization on a slower network are hard to ignore, especially when more and more of my own traffic is HD video streaming over WiFi.

Now, all we need to balance this out is some of that nice Google Gigabit Fiber to my house please, and I'll maximize my WiFi-based downloads.

Gig WiFi adoption
It's interesting how much more quickly 802.11ac is rolling out in products than its predecessors did. Readers, are you more likely to upgrade for greater throughput or more capacity?
