Today’s post, instead of your weekly Podcast on some Wireless LAN topic, will be the first of a three part series on Spectrum Analysis. This is a highly graphical topic, and though important to the working of a Wireless LAN Professional, is hard to do in an audio format. Thus no podcast, but instead I’ll be sharing slides, graphics, and concepts that I’ve been sharing with my students for the last decade… all in PDF format so we can visualize the concepts.
This week is Part 1 – Fundamentals.
In the attached PDF white paper we’ll cover the basics and vocabulary needed to get started with Spectrum Analysis. Including talking a bit on how regular WiFi NIC’s operate. We need to know what spectrum analysis is NOT as well as what it is.
In subsequent weeks we’ll continue talking about basics of Spectrum Analysis and then how to intepret the results of using a SpecAn.
In the final week, I’ll talk about the various options available from $50 to $20,000. And the costs and benefits of choosing your Spectrum Analysis tools wisely.
I’m no longer teaching WLAN technologies full-time, I’ve taken a position with Ruckus Wireless to head up the professional services group, so I thought it would be appropriate to share these concepts and slides freely to the Wireless LAN Professionals community.
Enjoy!

Comments and questions are always welcome.
In lieu of a podcast this week. I’ve included the following short white paper written by Jared Griffith and Keith Parsons as an “How To Guide” to using IPerf and Jperf network performance tools. Feel free to download this PDF document and share it with your friends and collegues.
Enjoy ‘Perfing’ you network.
For those of you with AirMagnet WiFi Analyzer and/or AirMagnet SurveyPro software – you can also use the IPerf service within those tools. Doing an IPerf site survey is a great way to PROVE throughput over your Wireless LAN.

The title of this week’s Wireless LAN Weekly episode comes from an article I read in the New York Times back in 1993. It seems the New York city parks department was having a bit of trouble with some overly rambunctious male youths terrorizing some of their female counterparts in the local swimming pools. They had started a trend of ‘whirlpooling’ by circling and taunting the girls in the pool.
To counteract this bad behavior, the mayor’s office came out with a marketing campaign targeted at the miscreants attempting to illicit better behavior. They made up posters, bumper stickers, and even had the mayor start wearing buttons that stated, “Don’t Diss Your Sis”.
In this episode we’ll be talking about Wireless Intrusion Prevention Systems running amok, causing harm to your own wireless network. Thus, “Don’t DoS Your Boss”.
Hopefully some of these stories will ring true, and you can learn from these mistakes others have already made.
Enjoy

This week marks a year since I’ve been posting and blogging on the Wireless LAN Professionals website.
In the past year we’ve had the following successes:
I am posting these statistics for two reasons. The first is to give me some incentive to get back up on that horse and start regular weekly podcasts again. I’ve been a bit lax lately, and I needed some incentive to get back in the groove of weekly podcasting. Realizing there is a fairly decent sized audience will do that for a guy.
The second reason, and probably more important to the readers of this blog. You have a community!
There is a thriving community of people who are interested in the career choice of being a Wireless LAN Professional. Well over 1,000 people that I can track put themselves in this category. So get involved! Follow along on the twitter streams, follow the other like-minded individual’s fantastic blogs, post comments and perhaps even start your own blogs on the subject. (see the website’s resources tab for more places to get involved)
I’m a firm believer that:
“Knowledge is like manure, if you spread it around, it will help things to grow. If you try to hold it yourself, you’ll just start to stink.“
So please get involved in this community. Start following others on twitter, share your information, post your posts, and just get involved.

Wireless Penetration Testing
Years ago, a friend of mine, Kimberly Graves and I had been teaching both CWSP and CEH courses. At the end of those courses, our students would ask to see our ‘instructor kit’. They wanted to have the bits that we used in class to show off Wireless Hacking.
Kimberly was the author to the Certified Ethical Hacker study guide, and I helped with the technical edits on that book. I was also a Certified Hacking Forensic Investigator and Licensed Penetration Tester trainer for EC Council at the time.
So to react to the market, we developed a Wireless Hacking Course… but couldn’t call it that – since some companies and government agencies wouldn’t fund training with the word ‘Hacking’ in the title.
So we called it “Wireless LAN Security Assessment Toolkit” – and it was a course than not only taught wireless hacking, but also came with all the parts one might have needed. Spectrum Analyzers, 5 WLAN NICs, access points, hand-held client devices, and all the software pre-configured, and finally, even a laptop to run it all on.
This was a wildly successful class in its time. Both Kimberly and I have moved on and now both work for vendors, Kimberly does Course Development and Training for Aruba, and I am now doing Expert Services for Ruckus.
A couple of weeks ago, I was asked if I had any materials on the flow of Wireless Penetration Testing…
So we thought it might be a good idea to take the materials we produced for the WLSAT course and release them to the public. We’re not releasing any copyrights… just allowing folks on the Wireless LAN Professionals website to download and use them for personal use.
Below is PDFs of the printed student materials included in the Wireless LAN Security Assessment Toolkit course. Yes, these are a couple of years out of date… but many of the concepts and techniques used are still valid today.
You can check out the old marketing web page with the details on the old course. We’ve included PDFs from each of the chapters, so you can download them one at a time if you’d like.
Enjoy!

I just wanted to post a new white paper on ‘Wireless LAN RF Design Fundamentals’ – let’s go back “old school” for awhile and see how we used to design RF for Wireless LANs…

This should have a sub-title called:
“Here Be Dragons” – sometimes I think people selling legacy WiFi equipment are like map sellers today trying to hawk their wares by selling maps showing dragons and the world as flat!
This week is sure to cause some controversy, but hey – that’s what these kind of things are all about. Something to get other Wireless LAN Professionals talking.
The show notes are in the form of a new white paper on this subject.

Twitter for the WLAN Professional

Twitter… What’s all the fuss about anyway?
You’ve heard things about this ‘social media’ thing, and wondered why everyone is talking about it. You might even have a Facebook page. But that’s just for sharing personal information about what you are up to with your friends and family. You also might be forward thinking a bit about your career and have already started a LinkedIn page, and shared your personal information and started to build your professional network.
Good for you, you’ve started down the path of adding some social media into your life. See, it’s really not all that bad.
Now on to the really powerful one called Twitter. I know, you’ve heard people talk about twitter, heard these funny new words like “tweet” and “tweeps”, and worse of all you’ve heard all people talk about is what they ate for lunch.

Apple Products as WLAN Professional Tools

OK, I know… everyone is going to think I’m just sort of Apple Fan Boy. And perhaps that is true. Not that I think Apple does everything right, far from it. But I have learned to appreciate the elegance in their design simplicity.
I like not having to do the dreaded “Backup, FDISK, Format, Load OS, Re-load Apps, reload data” thing every six months or so.
I like not having to deal with viruses and malware on my working machines.
I like the speed and simplicity of moving to a new laptop – mere minutes of my time, not the full-day it used to take in a Windows platform.
I like the ability to quickly move installed apps between machines without resorting to registry edits, and having to re-install from the original disks. (I know they are here somewhere…)
But most of all. I like this these products “just work”.
I also know many of you are hard core into the CLI world, and LIKE to do things your own way, and it rubs you wrong to HAVE TO do things (like iTunes) Apple’s way.
All that being said, this podcast is about how I use Apple products, like an iPhone, iPad, and MacBook laptops to help me in my work as a Wireless LAN Professional.
Let’s start with the biggest, and move to the smaller options
