I was on a trip out of town a while back... as soon as I crossed into another cellular network boundary, I got a call from the provider's sales droid, telling me how to use their service. They _are_ tracking individual phone movement, IMHO.

That's a feature, not a bug. When your phone hears an ident message broadcast from a cell whose system ID doesn't match the home system ID, it will emit a "here I am" message. The foreign cell can be programmed to send a "welcome, roamer" message, to log the entry into a file, or whatever. Within individual systems, there's no built-in capability to follow a phone. For example, the local BellSouth cellular operator can tell that _right now_ my phone is in the Harvest cell, and it can later tell that I've moved to the Decatur cell, but it won't automatically do so unless asked. - -Paul - -- Paul Robichaux, KD4JZG | Catch the wave with Mosaic for CLIX! perobich@ingr.com | newprod -n newprod@poboy.b17c.ingr.com Of course I don't speak for Intergraph. -----BEGIN PGP SIGNATURE----- Version: 2.6 iQCVAgUBLgWhUqfb4pLe9tolAQGQlAQApdOAdX90mzl4fxHwqukc1rB0vPhfCkUF AaC3NHULNrcengudDfFeGYuH7+cCGjLRFo27XNGxMeytDcQQVa63snqohi7icsoK O/yMFDkpxqwyzLxNukCysXLxgkZXt9YMlhXYHi3E3Xcx4fr4VE0ofFNggi2oha9y dy8jbD8dfHU= =O4Q/ -----END PGP SIGNATURE-----
