Kevin Sandlin from the CWNP program starts out the show with a couple of announcements about the CWNP program for 2010. Specifically talking about the return of the CWAP certification, the new CWDP certification, and how these will effect the future of the capstone CWNE program.

For the second half of the show, we’ve brought back Jennifer Huber – to talk with us about some of the issues and pitfalls in designing and implementing a Real Time Location Tracking system.


Here’s a link to the actual announcement of the new CWDP program, the return of the CWAP, and the changes to the CWNE requirements.

New logos for the various programs as well.

CWTS - CWNA - CWSP - CWDP - CWAP - CWNE Logos

CWAP® – Certified Wireless Analysis Professional
The CWAP certification is a professional level wireless LAN certification for the CWNP Program. The CWAP certification will advance your career by ensuring you have the skills to successfully analyze, troubleshoot, and optimize any enterprise Wi-Fi network, no matter which brand of Wi-Fi gear your organization deploys.

CWDP – Certified Wireless Design Professional
The CWDPTM certification is a professional level wireless LAN certification for the CWNP Program. The CWDP certification will advance your career by ensuring you have the skills to successfully design enterprise Wi-Fi networks for a variety of different applications, deployments, and environments, no matter which brand of Wi-Fi gear your organization deploys.

CWNE® – Certified Wireless Network Expert
The CWNE (Certified Wireless Network Expert®) credential is the final step in the CWNP Program. By successfully completing the CWNE requirements, you will have demonstrated that you have the most advanced skills available in today’s enterprise Wi-Fi market.
The CWNE certification assures that you have mastered all relevant skills to administer, install, configure, troubleshoot, and design wireless network systems. Protocol analysis, intrusion detection and prevention, performance and QoS analysis, spectrum analysis and management, and advanced design are some of the areas of expertise you will need to know.

Thanks to Kevin for sharing this information about the updates to this Vendor-Neutral Wireless LAN Certification Program.


Thanks too to Jennifer Huber to take the time to talk about some of the issues surrounding designing Wireless LANs for Real-Time Location Tracking with RFID.

Here are some of the links and notes from our discussion.

Jennifer did the math to find the percentages of additional APs required for a given type deployment.

Voice is from 22% ~ 26% more APs than Data only deployments
Location is from 25% ~ 43% more APs than Voice deployments

The low percentages are for standard office environments, the middle ground is educational facilities, and the high end is health care environments.

I didn’t factor for warehouse/manufacturing environments.

The Cisco LBS accuracy is stated as being within 10 meters 90 percent of the time

Recommendation for re-calibration semi-annually in an active logistics shipping & receiving area

Minimum signal level thresholds

Access point placement

Tips for successful (client) calibrations

“First and foremost, it should be clearly understood that 802.11b asset tags that transmit tag messages using Layer 2 multicasts (and do not attempt to associate to any WLANs) will not cause the initiation of any 802.11g protection modes under any circumstances. This includes asset tags operating in strict compliance with version 1 of the Cisco Compatible Extensions”

  1. Thanks for the great segment on the changes to the CWNP certification track! I've been wondering what my recertification was going to be like.. After playing back what I said about the RFID/LBS project I was working on I realized that I left a lot out of the show notes links I sent – so I compiled some links to supporting documentation for LBS deployments.. –> http://bit.ly/caGHBJ

  3. Thanks for the updated links. I added them to the body of the Show Notes! Thanks again for your help and expertise for this episode of the Podcast.

  5. First, thanks for the update on the new CWNP certs. I recently bought the original CWAP book and really like it. Version 2 will rock ! I am glad that a wireless design cert will become available, the CWDP. No such thing exists right now. There is so much to cover, voice, data, RTLS, video, performance, density, outdoors designs, indoors designs, wharehouses, signal bleeding, antenna choice… I am really looking forward to it.

    Thanks to Jennifer for sharing her RFID/RTLS experience. This is one of the most obscure WiFi disciplines to me, as opposed to data and voice over wireless.

    • I too am looking forward to the CWDP book/course/cert — there is a lot of knowledge there to be covered. Hopefully it will help all of us make/design/use better wireless networks.
      Thanks for your comments! – You've got a great blog by the way.
