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.

Since launching Connected Mobile Experiences (CMX) – Cisco’s innovative solution that turns the network into a platform for delivering location-aware, in-venue services – customers have been intrigued. However, CMX could not exist without the Cisco Mobility Services Engine (MSE), a location-aware network appliance to provide location-aware capabilities as well as deep wireless security.
Before I get into the new pricing details, here’s a quick recap of what the MSE can do:
The MSE is a network appliance that takes your wireless network and turns into a platform for delivering cool and innovative location-based services that provide unique business value through online, onsite and social analytics. For example, you can now leverage your wireless network to see how many customers are visiting your store? Are they new or repeat customers? Are long wait times at checkout hurting my business? With the MSE, organizations can even communicate directly with visitors in their venue through their mobile devices. You can now provide wayfinding (indoor GPS) and push relevant content such as offers or coupons directly to your visitors, which in turn can drive revenue gains for the venue.
The MSE does more than location based services – it also has a rich set of network security tools (known collectively as wIPS – wireless intrusion prevention system) that help protect the network from all kinds of attacks. The MSE can not only tell you that there is an attack taking place, but it will tell you which type of attack (“honeypot”), where the attack is coming from, and will also enable the network fight back against the attack (“flood the attacking device with traffic making it impossible for him to do anything”).
We wanted to make this great functionality more accessible and affordable for our customers, so I am happy to announce that we are offering a new pricing promotion for MSE licenses starting now until April 2014.
Here are the basics of the promotion: Read More »

Microsensors in your shoes compile data on where you go and how much you walk or run. Your workout clothes track your daily progress at the gym and tell you when to slow down or speed up. The pill you swallow reports back on the state of your digestion, vital signs, and overall well-being. And as you sleep, a headband monitors your REM patterns.
A far-fetched sci-fi fantasy? Not at all. It’s merely a glimpse Read More »

“I confess that in 1901, I said to my brother Orville that man would not fly for fifty years . . . Ever since, I have distrusted myself and avoided all predictions.” — Wilbur Wright, 1908
In SDN in the Enterprise: aligning with business needs I highlighted one of what some people are claiming to be the most disruptive technologies in the networking space in recent memory: Software Defined Networking (SDN), or what I like to call the continuation of the abstraction of everything. Today we’ll explore some of the ways I believe SDN will and will not change networking.
Trying to predict the future in any endeavor is fraught with danger, or at least substantial risk of embarrassment. Winston Churchill once said, “I always avoid prophesying beforehand because it is much better to prophesy after the event has already taken place,” and he was on to something. Technology predictions, in particular, seem to have a funny way of getting away from even the most intelligent and business-savvy among us. Hit the target, and you look like a genius. Miss it, and if you have a high enough profile people will remember it forever. Worse than that, however, is that in business if you miss the target you leave money on the table, or in the worst cases sink the company. Read More »

When? Thursday, August 8, 2013 @ 1:00 – 2:00 p.m. (EDT)
Where? Twitter Chat
The explosive growth in mobility is transforming the ways in which we live, learn, play and, in particular, work. Every dimension of our business lives stands to change: whom we work with and when, where, how, and why we work — all will be impacted.
The ultimate goal of business mobility is to drive increased productivity, heightened customer experience, and harmonious work-life balance. Business mobility offers freedom for knowledge workers beleaguered by accelerating demands on their time and talents; with it, they can take control of their success at work while protecting their personal lives. And, increasingly, it is the knowledge workers themselves who are driving these sweeping changes in the workplace.
But how can service providers and enterprises embrace the disruption?
Join us this Thursday, August 8th at 10am PST/1pm EST for a TweetChat on how next-generation knowledge workers are accelerating the disruption in business mobility. Follow #CiscoYourWay to join in on the discussion. I’ll be tweeting from my own handle @Spain_Chris. Read More »
