A key use of a cell phone
is to contact emergency services
while on the road.
However, many people in the act of travelling
are not able to coherently
relay their location
to 911 dispatchers
. A cell phone with a built in GPS
reciever, however, could send the phone and caller's location to a dispatcher automatically
. The Garmin Navtalk
already does this.
According to the news blurb
I saw this on, this technology will become a requirement
in a few years.
I saw this coming when Bill Clinton
ordered Selective Availability
enough the idea was also portrayed in the Charlies Angels movie
(although to the fakest degree). Some guy in Citrix
class even mentioned
it a year ago.
There is some opposition
.... Certain safegaurds
will have to be taken to make sure the GPS information can't be exploited
. For example
: An unchecked wireless provider
could monitor everywhere you shop the day after Thanksgiving
and sell the information to JC Penney
The combination of hundreds of cell phone makers, thousands of wireless providers, and the fact that pretty much everyone and they're kids
have a cell phone will make this a fairly hefty
