11 Days! That is just one of the stunning statistics from an AT & T infographic that I saw recently. The infographic also compares how long it took to reach the same number of connections in years past. Check it out – you’ll be amazed! Much of the additional data is of particular interest to those in the Hospitality and Retail Industries.
Rather than re-invent the wheel, I’ll point you to a great blog post from Slashgear.com that pretty much says everything that I would regarding the data.
OK. If you have been following my blog (here or over at Computerworld), you’ll notice that I am really starting to incorporate a lot of video into my posts. So far, I have found that one of the easiest & most effective ways to include video is to interview someone else. However, I now realize that turn-about is fair play.
The fine folks at CWNP had a little fun by asking me what I though about their recent Certified Wireless Analysis Professional (CWAP) beta course.
I told them about one mantra I hold about wireless networking… that the packets never lie. Then they took some liberties with my response. 🙂
See for yourself:
Oh, it’s all in good natured fun. That is, if you can stand seeing & hearing me more than 10 times in under 5 minutes… In all seriousness though, I had a great time at the CWAP beta course and learned a ton from all the real brains in the room.

It’s true. I took a new job with Cisco. I am now working as a Mobility CSE (Consulting Systems Engineer). I am specifically working on Enterprise accounts within Cisco’s Pacific Southwest Operation.
I was joking with my manager that I needed three things from Cisco before making a more official announcement on taking my new position – a badge, a laptop, and a pay check. In my opinion, that’s the Cisco hat trick! 🙂 (For those of you who don’t know, I am a *huge* NHL hockey fan). I’m happy to report that I have been on the job for approximately a month and right now, drinking from the firehose.
For all those who want to take a drink with me, here’s a great 5 minute video on one of Cisco’s newest products – the Identity Services Engine.
If you read my latest posts, you already know that I attended the Certified Wireless Analysis Professional beta course hosted by the CWNP program in Atlanta, GA last week.
I really enjoyed all the side bar discussions between attendees. There were at least 3-4 vendors represented, as well as VARs/Integrators and enterprise wireless network administrators. I spoke about my favorite side-bar discussion, which was about locating wireless devices through spectrum analysis on my Computerworld blog.
Attending the course also really reinforced what a big believer I am in the CWNP program. It’s great to see a vendor neutral training and certification body in our field. I really think that along with the IEEE and Wi-Fi Alliance, they have done a great job promoting and educating the community about wireless technology, which helps drive growth / adoption, which is good for everyone involved.
Therefore, I wanted to take the time to interview one of the CWNP co-founders, Kevin Sandlin, to have him explain about the program and how it fits an emerging trend in the marketplace:
Today was the 2nd day in the CWAP (Certified Wireless Analysis Professional) beta course. Today’s material was a lot more hand-on / lab type exercise in capturing and analyzing traffic. From what I could tell, there were three main tools used by the course attendees:
They all seem to have their pros and cons, and they all seem to cost about the same amount of money (especially if you want to do multichannel packet capture on ~3 channels). Which tool do you prefer? Why?
The course contains an enormous amount of detail, such as the exact length (in microseconds) for slot times for each PHY type as well as a discussion on the application of that detail (i.e. how do the different slot times affect WLAN performance with and without QoS enabled).
Again, I thought one of the most valuable things were the networking opportunities with the other attendees and the sidebar conversations. A colleague (and good friend) of mine, Ken Hall, was even inspired to sign up for a Twitter account (@wifiscubaguy) to continue the interaction outside of this course / classroom. His account will definitely be on my next list of #WirelessWednesday mentions.
Tomorrow is the last day of the course. From what I know, we are covering a lot of 802.11n concepts, as well as spectrum analysis, which should be a blast.
This week, I am at the CWNP offices in Atlanta, GA for training. If you’re unfamiliar with CWNP, they focus on vendor-neutral training and certification in the wireless networking space.
The program recently went through some changes, and they recently launched two new certifications:
I am here taking a Beta version of the CWAP course with some of the brightest minds of the WLAN world. One of the authors of the new CWAP Study Guide, Peter MacKenzie, is teaching the course. Two of the other authors are attending the course – Marcus Burton and David Coleman. There are also some of my favorite wireless bloggers in attendance, including:
Today, we covered a lot of ground with regards to the Physical and Data Link Layers and what the bitwise fields look like at that those levels. However, from my perspective, some of the most interesting discussion was not around the bits and bytes, but rather how an understanding of those fundamentals can be applied to real world wireless troubleshooting and analysis.
The afternoon consisted of some hands on work with protocol analyzers. Peter taught this in a very dynamic way just stepping through captures we were all taking on the fly — very impressive!

I told you there was more to come on this one…
The project for the United States Tennis Association (USTA) was done in conjunction with a partner of ours, Signal Share. I can tell you, Signal Share is doing some exciting things in the wireless space.
The U.S. Open also had other arrays that were installed in a more permanent fashion. This is a picture of one such array taken from the perspective of where array in the first array was located.
It’s been awhile since I have done a “Super Tuesday” poll, so I thought I would throw one in today. You should answer this question for your primary computer, whether that be a desktop, a laptop, a tablet PC, or whatever.
I can’t give any “I voted” stickers away, but take satisfaction in the fact that you are shaping the (wireless) direction of America…. 🙂
