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.

Infonetics recently published our Enterprise Networking and Communication Vendor Leadership Scorecard, our annual look at the top vendors in this space and their strengths and weaknesses. Enterprise networking and communication infrastructure is a critical component of the day-to-day operations of any organization—it connects people, devices, and IT systems and allows them to communicate with each other securely. This market consists of 3 major sub-segments:
“Growing up is never easy. You hold onto things that were. You wonder what’s to come. But that night, I think we knew it was time to let go of what had been, and look ahead to what would be. Other days. New days. Days to come.” – The Wonder Years
I’ve always liked this quote from one of the best TV shows of all time. And in an age where things are constantly changing, it’s never been more relevant. Today’s grandparents and parents spent their childhood in a world without sensors, smart phones and network capable devices at their fingertips. Our children, however, are growing up in a drastically new world. A world where everything is instant, where networked devices are part of their everyday lives and technology is in everything they do. This world enables unlimited potential and unlimited connections that can impact a child’s life for the better. So how will the Internet of Everything (IoE) prepare children for the smart people network they will live, learn, work and play in?
Have you heard? Many organizations are now realizing that they can leverage location-based services to provide personalized mobile experiences and customer analytics. It pays to stay connected to your consumers and enhancing the mobile experience. Today at Interop New York, we unveiled a number of new product and solution innovations built to expand on and extend the power of Cisco Unified Access to drive these new connected mobile experiences.
Nearly one year into announcing our Connected Mobile Experiences (CMX) solution, and with today’s announcement, there’s even more. We’re kicking off a deep dive blog series to give you an in depth look at the new enhancements, but for now here’s a taste of what’s new:
CMX for Facebook Wi-Fi allows retailers, hoteliers, restaurants, and more to engage and analyze customers and guests using the Cisco and Facebook Wi-Fi platforms. It enables guests to easily connect to the Wi-Fi network using their Facebook credentials and “check-in” to the venue’s Facebook profile. The check ins give venues additional marketing and branding opportunities through broadcasting through guest news feeds, as well as valuable demographic information. See how a conference center, Evergreen Brickworks, is using the solution:
Enhanced onsite analytics have a revamped UI to show you how, where, and when customers and visitors are moving throughout a venue. Read More »
