Getting Started with the CCNA Wireless

I would like to take the opportunity during this first post to re-introduce myself. My name is Brandon Carroll and I am an Instructor at Ascolta training, as well as the Author of the new book: CCNA Wireless Official Exam Certification guide. I have been an instructor for 8 years and I teach classes that range from Routing and Switching, Security, Voice, and Wireless. For the next month I will be blogging here at Network World and who knows, maybe after the month is over I'll stick around. I am a reader of Network World myself and would love to continue to blog here if my schedule permits. I don’t want to get into a great deal of technical content on this first post but I don't want to leave you with a simple, "Hi How Are Ya!" So, I thought that I would begin with a little overview of what my book is about, and some information on the exam that the material covers. What I’m talking about here is the CCNA Wireless Specialization. Here are some things to know:

  • -It doesn’t replace the CCNA, it adds to it’s value
  • -It doesn’t prove that you are a Macho Man (or Woman) rather it proves that you have an Associate level knowledge of Wireless Networking and the Cisco Unified Wireless Network Solution.
  • -It can be a little tough but you can get through it!

For those of you that are moving from the wired to the wireless side you will have to get used to some new things. First off, consider the rules. In Wireless World you have to follow some Country Specific guidelines. Here in the U.S. where I am at, I have to follow FCC guidelines. In Europe it would I would have to adhere to regulations set forth by ETSI. The important thing to remember here is that regardless of where you are, you will have some guidelines that you have to follow. Now, as I mentioned, the FCC sets some guidelines here in the USA, but that's not where it stops. There is also the WiFi Alliance, the IEEE, and the ITU-R. All of these organizations come together to make wireless what it is today: Simply Amazing! Still, understanding that these organizations exist isn’t enough. You should really have some sense of the standards they bring to the market as well as what they are designed to do and how users interact with them. In my next article we will discuss some of those standards, including:

  • -802.11a/b/g & n
  • -ISM Bands
  • -DSSS
  • -OFDM
  • -MIMO

After a look at these standards we can discuss some device configurations that can be hairy for those new to wireless, and we can also discuss how to prepare for the exam, what you need to build your own lab, and what approach will help maximize your time and energy while studying. Also, watch my future posts for more information on some free WebEx Webinars that I will be doing to discuss some of these topics in more detail, hosted by Ascolta. I look forward to an energetic month of sharing information and I welcome any questions, comments, or ideas. If there is a topic that enough people are interested in I will be discussing it.
