tl;dr: WLAN traffic is encrypted in the main channel, but side-channel traffic can be intercepted, examined, and used to determine some of the information in the main channel.

Sorry but a bit of a different subject - what does tl;dr mean? Because I googled this and it says that it means "Too long, didnt read". It's for my own info, for another situation :)

That link isn't working for me, do you have a saved copy? I normally grab stuff and save it local if it's important in case it gets removed or breaks. I have a folder called "config guides and useful web pages"  :awesome:

tl;dr means what you found. "The tl;dr" is the shortest summary of a long read.

Attaching the file to the thread, why not?

Finished with Section 2... my big takeaway from this is that mobile devices are most susceptible to side-channel data gathering because they are least likely to pad out packets and stagger request times - they want max throughput and data delivered upon demand.

If you're using a PC, run BitTorrent to mess with anyone trying to figure out your other traffic. Also, the timing and length of standard English-language Skype conversations allows them to be decoded to some extent. Specialized vocabulary and/or regional accents can throw such efforts off.

In general, even though wifi itself encrypts everything below the 802.11 header, those headers themselves allow for a rich amount of metadata that is available for anyone to intercept and mull over.

On to section 3.

Section 3 dealt with the ethics involved in setting up the experiment... can go straight to summary, if you like.

Section 4 is about collecting the data, reading that now... OK, read that, it's basically a how-to DIY guide.

Section 5... this is where the findings are presented... reading that now...

This is a thesis for a doctorate in philosophy? Am I the only one finding that odd? lol

It's a PhD in Security and Crime Science. :doh:
