In 97 countries around the world, there are now more mobile devices than people. No wonder mobile networks are clogged with massive amounts of new traffic! Mobile operators are struggling with how to provide the mobile broadband experience customers expect, in a cost-effective, scalable, and profitable manner. I believe that Wi-Fi, the “silent sleeper” of wireless access networks, may hold the answer.
The mobile industry is on the brink of a fundamental change. Just think of some recent key developments:

Over a billion mobile devices are online today. Just last quarter, Apple sold 52.4 million iPhones and iPads. The airwaves are humming, and there’s already traffic congestion along the mobile services highway.
The Cisco Visual Networking Index (VNI) report released on February 14, 2012 predicts that the volume of mobile data traffic will grow 18 times over by 2016. That totals 10.8 exabytes per month by 2016, nearly 11 quintillion (1018) bytes: a staggering number, five times the volume of the entire global Internet in 2005.
Will your mobile infrastructures be ready for all that traffic?

Last week, I took my girls to their first Stanford Women’s Basketball game, a well played game against the University of Oregon. While there, I noticed that almost every person had a smartphone out at least once during the game—and for good reason. Stanford has upped the live sport experience for spectators.
By connecting to the pavilion’s Wi-Fi network with a smartphone, you can order and pay for concession-stand food from your seat. So, you don’t have to worry about missing anything. Plus, you’re able to view replays, participate in contests to win prizes and even play mini-games.
From connected stadiums like Poland’s new National Stadium, which will host the 2012 European Football Championship, to connected cities like Songdo South Korea, Cisco is helping to dramatically improve our experiences and quality of life by capitalizing on the power of the network.

Not too long ago I was assigned to a troubleshooting and remediation project for a hospital here in the SF bay area. The problem, after much troubleshooting and lab recreations, was determined to be due to an unique issue with client roaming and authentication. During the course of troubleshooting my coworker and myself often found ourselves explaining 802.1X and 802.11i to others working on the troubleshooting effort, or requesting technical updates. So based on that experience, I started thinking this might a be a good topic to cover here.
Let’s review the some of typical components of the enterprise wireless security model.
What is 802.1X?
802.1X is not a protocol, but rather a framework for a “port-based” access control method. 802.1X was initially created for use in switches, hence the port-based terminology, which really doesn’t fit too well in wireless since users don’t connect to a port. In the end it’s meant to be a logical concept in the 802.11 world. 802.1X was adopted for wireless networks with the creation of 802.11i to provide authenticated access to wireless networks. At a high level. the framework allows for a client that has connected to the WLAN to remain in a blocked port status until it has been authenticated by a AAA server. Essentially the only traffic allow through this virtual blocked port is EAP traffic, things like HTTP would be dropped.
What is EAP?
EAP (Extensible Authentication Protocol) is the authentication method used by 802.1X. It can take on various forms, such as PEAP, EAP-TLS, EAP-FAST, to name a few. There is one thing to remember when determining what EAP type to use in your network, is that it is dependent upon what your client and AAA server supports. This is it, your AP or AP/Controller hardware or code version will play no part in version is supported. Unless your AP/controller is acting as the AAA server, but I’ll stay away from that in this post. I think this can be a point of confusion for people who haven’t read much or anything about EAP methods. So, if some one asks what version of EAP the AP will support, all you need to do is ask them, what does their Client and AAA server support.
What is 802.11i?
Simply put, 802.11i is an amendment to the original 802.11 standard to address the well documented security short comings of WEP. It incorporates WPA as a part of the 802.11i amendment and adds the fully approved WPA2 with AES encryption method. 802.11i introduces the concept of a Robust Security Network (RSN) with the Four-way handshake and the Group key Handshake.

Earlier this week, we kicked off special customer guest blog series with Andrew vonNagy, author of the blog Revolution Wi-Fi, and active on Twitter @revolutionwifi. Join us today as Andrew explores the next two major retail trends changing the Wi-Fi industry, and catch up with the first part if you missed it.
Trend 2: Empowering Sales Associates
Given the increasingly connected and smart shopper, consumers now have more product information than in-store sales associates in many cases. Yet sales staff are key to providing a great consumer experience in-store. Retailers need to empower sales associates with the depth of product information that consumers have, and to provide additional tools that facilitate existing and new services offered by the retailer.
Historically, only a fraction of retail sales associates have been provided with mobile devices, and those devices have enabled only a limited set of capabilities such as stocking, inventory management and product availability. One reason for this is the high cost of ruggedized mobile devices for use in retail. A typical high-speed scanner PDA can cost well over $1,200 each. In order to provide every sales associate with more information to help consumers, retailers are adopting lower-cost, feature-rich, smart mobile devices that provide more robust capabilities than specialized scanners. Mobile platforms built by Apple, Android, and third-party manufacturers are enabling this shift, along with a retail IT focus on enabling business processes in a more flexible, consistent, and re-usable fashion.
