I spent a lot of time in 2006 and 2007 working on the WiMedia Logical Link Layer Control Protocol specification (WLP spec for short). Publishing a specification like WLP is a lot like filing a patent. You do a lot of the work early on, and then the actual publishing process takes a really long time. It's almost anti-climatic when it does finally get published.

In any event, it's available on the WiMedia web site if you're interested (unfortunately there is a click-through license agreement that you must fill out to read the spec). I worked on the security sections, sections 6.6 and 7.2 and annexes A and C.
