Wireless Provisioning Service Protocol

i am not sure if the question is to be impressed. it is simply true  
that some signaling is necessary to allow user to choose a network  
(e.g. an operator). in usual hotspots you end up with a web page  
which can present you all the information you need (e.g. prices,  
names, available services, etc.) - however without any L2 security.

but in 802.1X you have to first authenticate to be able to exchange  
any signaling. this is indeed insufficient e.g. for WISPs: how do you  
know that your authentication will work in a particular network?  
which authentication protocol should you use if it does not? what  
will you pay by accessing there? which service do you get? etc. etc.  
etc. all these things become terribly complicated. in fact, i've  
written a paper on that about two years ago... using something like  
TTLS/PEAP provides a tunnel which you can use to exchange any data  
with the operator's control plane, and that prior to IP.

could you be more specific?
