802.11ac: The Fifth Generation of Wi-Fi Technology
In the last few months, there have been a lot of written on the emerging 802.11ac standard. This next generation of Wi-Fi promises to be very exciting since 802.11ac will address some critical pain points faced by users of 802.11n today – more bandwidth and more simultaneous users. To help explain the technology, we put together a new Fundamentals video. You’ll learn about new features such as:
- Operating in the 5GHz band
- Wider channels (80MHz & 160MHz) which means more capacity in the band
- Increased modulation with 256 QAM (Quadrature Amplitude Modulation), providing a significant increase in throughput over 802.11n which has 64 QAM
- Downlink Multi-User MIMO which allows an AP to transmit to multiple clients simultaneously
- Up to 8 Spatial streams which doubles the number of spatial streams used in 802.11n

Until now, it’s been assumed that enterprise IT leaders probably view the current BYOD (“Bring Your Own Device”) movement with about the same enthusiasm as a farmer awaiting the next locust invasion.
A recent survey from the Cisco Internet Business Solutions Group (IBSG), however, indicates that BYOD may no longer be a “four-letter word” in enterprise IT departments. In fact, the study of 600 U.S. enterprise IT leaders—all from companies of 1,000 or more employees—shows that, if anything, BYOD now has a predominantly positive reputation in U.S. enterprise IT circles.

As I flew home from Interop Vegas the other night – quick side note: the event was great, check out an overview and a few fun TechWiseTV Videos: Keynote from Padma Warrior , Managing Beyond BYOD, Is Your Network Ready for Cloud? - I realized that my kindle was not accessible, my laptop was dead and I’d already read the in-flight magazine. Given the close quarters of the commuter plane, I decided it would be okay to peek at what my neighbor was reading. As I glanced over, he turned to an article with a headline that screamed “It could happen to you!!” I then noticed it was a combat handgun magazine and decided I would give him some space.
With no reading materials, I started thinking about all of the situations that we as individuals and as organizations get into that feel secure, but which can actually be quite threatening. Those are the situations that make having insurance worthwhile. When it comes to security on the wireless network, nobody expects hackers and rogue attacks to infiltrate their network, but all of the smart network managers prepare for it anyway.

It’s not new news that when it comes to network access, Wi-Fi technology is a cost-effective complement to macro radio access. Industry blogs continuously feature analysis about the economic advantages of using Wi-Fi as a small cell technology. No surprise, then, that many mobile operators have completed or are working seriously on plans to integrate this technology into their mobile ecosystems.
But when it comes to details, things start to get confusing. Terms like policy and charging, lawful intercept, mobility and SIM authentication start to pop up. The Third Generation Partnership Project (3GPP) has incorporated Wi-Fi (non-3GPP IP Access) as part of the LTE architecture, created the terminology and studied the Read More »

Navigating the BYOD onboarding process
I am not a car person. When asked to describe a vehicle, I start with color and the number of doors. Then I stop talking. However, for a short time, I worked for a luxury autos website. I could pick out a Maybach on the streets of Manhattan, I knew when Tesla was launching a new model and I could tell you which James Bond movie featured a vehicle other than an Aston Martin.
Now that I spend my days thinking about wireless networking and mobility, I’ve realized that my perception of Vegas has completely changed as well. Plans used to revolve around restaurants, craps tables and night clubs. Now, as I get ready to head to Interop Las Vegas 2012, I find myself wondering about the network. With thousands of participants simultaneously trying to gain connectivity with all of their mobile devices, I think about mitigating network interference, being prepared for high density and maintaining security for the participants and vendors at the event.
If you’re headed to Interop and these are things you wonder about as your network is growing, here is a heads up on the demos and speaking sessions that you cannot afford to miss.

How BYOD is Driving Change in the Campus Network
The drivers of change in the campus network include the requirement to support a significant increase in video traffic, the need to support the movement of virtual machines within the campus data center and the burgeoning movement to bring your own device (BYOD). The panelists in this session will discuss technologies and design options that you can use to redesign your campus LANs.
Check out our Insider’s Guide to Interop for a list of great events covering Borderless Networks – everything from BYOD, to WAN Optimization and Cloud Connectivity! Thanks to Lauren for the great scheduler!
And if you were wondering, my car is a goldish, tan, four-door. And (just for fun) these are 007′s cars… not quite the same thing. Maybe one day!
