802.11 Wireless cheat sheet

This cheat sheet took considerably longer than average to produce, as I found myself constantly being refamiliarized with the myriad of components which make up wireless networks. Laborious as it was, I'm pretty happy with how it turned out. And thanks to Brandon Carroll for helping review an early draft!

As always, if you notice any errors or omissions in the document please be sure to let me know and I'll do my best to get them corrected. I've been pondering an opt-in mailing list for people who want to receive draft copies of cheat sheets and help me review them for errors or omissions. Thoughts?

Very good mate, now if only companies would pay CSIRO their royalties N could be ratified :(

Where do you get the 802.1p values from? I know there's a recommended class map table in the 802.1Q-2005 Annex G, but it doesn't look like what you show there.

Still an excellent reference, as always.

Nice work on this, as well as on the rest of the cheat sheets.

Amazing, your previous cheat sheets have been a great reference for me at work and whilst studying.

Like the others, this will be going in the reference folder. Keep up the great work and thank you!

Another excellent cheat sheet, although the information I have for 802.11a channels (FCC/ETSI) is 23/19? But this is from Cisco information using 802.11h, and I haven' been able to validate?

Thanks a lot, I've already used it once today. Great work.

Excellent work, I love these cheat sheets.
I would say Maximum Data Rate instead of Throughput as the real Throughput in WLANs are much less than the data rate.
