The ability of a landline call to be traced to a location is inherent in the
landline net work (each phone number is mapped to an address). For mobile
networks
the ability to locate a phone is also inherent, but on a much coarser level.

Every wireless phone must be located in a "paging area" or else calls cannot
be
completed to that phone. This is true of all wireless telephony systems
(AMPS,
TDMA, GSM, CDMA, iDEN, etc). No set size for this "paging area" exists, but
it
can be as small as a single cell site and sector or as large as an entire
country.

As for the the US, the `Wireless Communications and Public Safety Act of
1999'
contains this text:

         `(f) AUTHORITY TO USE WIRELESS LOCATION INFORMATION- For purposes of

                subsection (c)(1), without the express prior authorization
of the
                customer, a customer shall not be considered to have
approved the
                use or disclosure of or access to--

                `(1) call location information concerning the user of a
commercial
                     mobile service (as such term is defined in section
332(d)),
                     other than in accordance with subsection (d)(4); or

                `(2) automatic crash notification information to any person
other
                     than for use in the operation of an automatic crash
notification
                     system.

So for US
