Hi -
Actually, there are any number of available technologies for determining the
location of a cell phone. While these may not be well known in the US, there
definitely are in Europe and Japan. I refer you to a white paper by Mobile
Lifestreams titled, "An Introduction to Mobile Positioning". I believe there
is a short version that is free and a lengthy (300+ pages) version available
for US $250.00. See also www.mobilePositioning.com. There is also an
excellent 3 paper series by John Davies available through
www.anywhereyougo.com. The real issue, as has been pointed out, is how you
track millions of mobile devices. But that is something I am sure the
telco's will figure out. Of more interest to me (being a geographer) is what
packaging, interface specs, and protocols will be used to communicate
"geography" with the devices. I refer you to the IETF BoF on SLoP. How is
that for a bundle for three letter acronyms :-) There are also some very
difficult security and privacy issues that are currently being heavily
debated.
Cheers
Carl Reed
