Re: [Geopriv] HELD and persistent TLS connections in emergency calls

Henning - .11 triangulation is farther along that you are eluding to, 
and will not be a rare observation, at least in public places.  Home 
networks with only a single antenna won't use triangulation, but 
there are other means being worked on to know what distance and 
vector an endpoint is at (with respect to where the single AP is).
