We (Cisco Advanced Services) are working to update a Beta class that discusses the secure use of voice and video over wireless.
Quick Question: If you had to put together a "wish" list of topics and lab exercises you would want in a HIGHLY technical integration class, what would it include? Please provide topics, equipment, technologies, or any other ideas you have.
The TOP item on my wish list would be a discussion on the importance of a good site survey. A good Site survey is critical to the successful deployment of a Wireless IP Telephony solution. Also, a guide on how to do one would be awesome!
I believe some specific discussion on WHY it is necessary to stay with Cisco certified components (i.e., in order to comply with Federal laws and standards for emission).
Some discussion on the specific components (cables, lightning arrestors ("they are not for direct lightning hits"), power injectors, using fiber for LAN isolation (from "environmental events").
Some discussion on radio wave propagation ... things it can penetrate, things it'll bounce from, things that will absorb the signal ... common items likely to occur in a commercial environment. Maybe some alternatives to dealing with "RF hostile" environments.
Some discussion on long range p2p / p2mp, sighting the antennas, the freznel zone, etc.
Discussion of third-party tools / software / hardware to improve the ease and quality of the installation.
I would like to see examples of through-put using the various security options available. Set the lab so you can use various manufacturers equipment and compare QOS and load. I would also like it to show the effects of distance, obstructions, and/or antenna patterns.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.
It is a living doc, so check back for changes every so often

I have created a Powershell script to automatically add a Wireless Guest User on Cisco WLCs. (tested on 2500 Series)
The script should be completely self explanatory.
