I am trying to understand the degree to which wireless service
providers globally are either today offering service level agreements to their
business customers, or plan to do at some point in the future.

I need an answer by noon MST on Monday 11/22.  I am looking for at
least one concrete example from a service provider.   I may have other
questions related similar questions in the future; I'm really just
testing out this service right now.

Sorry that I have seen your question late and I am not sure if you
need the answer now.

For most of your questions the answers might be at "Satellite Industry
Association", url:http://www.sia.org/.

Another article I must mention which might be helpful. Please visit
