Marc,

I don't quite not where to start since your response is so utterly
incorrect, and full of misrepresentations.

You seem to imply that 3825 is about "self-measuring" device, there is
no mention of this in 3825 at all. In fact 3825 says:

"This document specifies a Dynamic Host Configuration Protocol [1]
   Option for the coordinate-based geographic location of the client, to
   be provided by the server."

To me this is clearly a network determined location, or is the DHCP
server in the end-device?

Just to cut your response before you start, I have wandered around quite
large areas of Dallas in the past with a differential GPS unit that
quite clearly provided me with a location as a circle, point with
radius, and not a "thick point".

Our position of representing uncertainty comes from NIST. But as you
point out, NIST is a cellular telephone technology provider that is
interested only in network determined locations.

I asked John S, a very simple question in an email yesterday, that he
has declined to respond to, I think that the answer to that question
would solve a great deal of trouble. Just in case it got lost in the
noise, I shall provide a link to it here:

Have a nice weekend

James
