By now you’ve probably heard quite a bit about the newest generation of Wi-Fi, 802.11ac. I’ll save you the gory details, just know it’s about 3x faster than 802.11n and will help to improve the capacity of your network. Jameson Blandford and I were recently guests on the No Strings Attached Show podcast with Blake Krone and Samuel Clements (Click to listen to the podcast).
I wanted to follow up the podcast with a blog to go over considerations for deploying, testing, and tuning 802.11ac.
Considerations for deploying 802.11ac
The first question you’ll want to ask yourself, is, if your switching infrastructure can handle 11ac? The answer probably is, yes. The things to consider are the port speed and power-over-Ethernet (PoE) capabilities. You’ll want the access point to have a gigabit uplink to the switch. Each 11ac access point could potentially dump several hundred megabits per second of traffic onto your wired network. It’s also not a bad idea to have 10 Gig uplinks on your access switches to distribution or your core. If you have even just a couple access points on a single access switch, you may quickly find yourself wishing you had 10 Gig uplinks.
Next you’ll need to consider how you will power the access points. If you are like the majority of our customers, you will use PoE from your switches. While 11ac access points require 802.3at (PoE+) for full functionality, the Aironet 3700 will run happily on standard 802.3af PoE. In fact, it remains 3 spatial-streams on both radios, so performance does not suffer because you have a PoE infrastructure.

Cloud-based computing is being viewed by schools, colleges and universities as an increasingly attractive option for delivering education services more securely, reliably, and economically.
Cisco cloud customer, Electronic Testing Services (ETS), took part in a joint webcast to discuss the economic advantages of cloud computing. If you weren’t aware, ETS hosts the advanced placement exam for students. Their previous infrastructure saw low utilization rates due to once-per-year exams. By using Cisco cloud computing, ETS now sees revenues more closely matching expenses.

I sat on a plane the other day with Walter Axe, 99 years old and a happily-retired former telephone company engineer, on the way to see his newest great-granddaughter. During the three-hour flight, Walter regaled me with stories of his life in the Bell System.
He joined the company in 1931, fresh out of the Army. He dug ditches, put up poles (often using teams of horses), ran wire, worked in the switch room, and ultimately ended up in Illinois, where he found himself in, as he describes it, “the best job in the world.” Intrigued, I asked what the job was.

In December, Cisco introduced Cisco CloudVerse, a framework and set of solutions that combines the foundational elements needed to enable organizations to build, manage, and connect public, private and hybrid clouds. Cisco CloudVerse combines these key cloud elements – Unified Data Center, Cloud Intelligent Network, and Cloud Applications and Services – enabling businesses to realize all of the benefits of clouds: improved agility, better economics, enhanced security, and a dynamic, assured experience.
As a leading technology company, Cisco pushes the envelope in our traditional industries with innovative business transformations, as we did by entering the server market in 2009 with our Unified Computing System paired with our Nexus data center switching family. Competition in the marketplace is good for customers as competition accelerates innovation, creates new opportunities as old problems are attacked from new angles, and creates incentives for the various players in the industry to work together–and separately–toward better solutions.
But achieving the promise of this progress and innovation comes with a necessary step that I feel is often overlooked, rushed, or ignored: Testing. At Cisco, we perform intense testing as we develop our solutions whether the testing is in-house, with partners and customers, or via third-parties.
Over 70 percent of leading cloud providers are using Cisco CloudVerse on their journey to the cloud, and–in the latest example of our commitment to testing–third-party testing firm EANTC has validated those cloud providers’ commitment by affirming “Cisco has all the components one would need to offer cloud services”. For coverage, Light Reading has published the first report of the Cloud Mega Test results done by EANTC.
But let’s talk more about what was behind the test.

Miercom, a privately held network consultancy, specializing in networking and communications-related product testing and analysis, conducted a report on the most popular web conferencing applications. Based on testing across a variety of variables, Miercom concluded WebEx “was overall the most advanced and best solution for handling web conferencing.”
