Last night was a pretty typical weeknight at my home, I drove home from work
and filled up with gas before I got home, I left my house again at around 5:30
to take my son to his Karate lesson. While I was out I stopped by the local
library to return some books and then swung over to the dry cleaners to pick up
my shirts and slacks and some stuff for my wife. I picked up my son from his
lesson and we stopped off at the grocery store to pick up some bread and milk on
our way back to the house WhatsApp Hacking.
Now, you aren't the first people to know my whereabouts that night. Because I
had my cellular phone with me, the cell phone company that provides my cellular
services knew where I was at the entire time. They tracked me with my cellular
How is this possible?
It is possible because people who use their cell phone need to be able to make a
call whenever and wherever they may be located at the time they dial the number
on their phone. Therefore, the cellular companies must be able to route the call
to the nearest cellular tower, which in turn sends your call to the satellite in
space, which sends your signal to the person you are calling. The tower that
handled the call is typically logged (and stored indefinitely) on the wireless
provider's computers, though it's not noted on the customer's monthly bill. In
order for the cell phone company to know what tower you are at, they must be
able to track the signal from your cell phone when it is on.
In the expanded age of advanced communication and the literally thousands of
issues of privacy that it has since spawned, many people would be horrified to
learn that they can be tracked by the phone company via their mobile phone. The
phone companies claim this is a integral part of the service they provide,
privacy advocates say that this is just another way large corporations have
invaded our lives.
Wading into the fray over this controversy concerning your cell phone is another
larger and important player: law enforcement. Law enforcement agencies are now
utilizing the technology of tracking cellular signals to catch criminals and
terrorists. A few cases of dangerous criminals being tracked and caught while on
their telephones have been documented and law enforcement is now fighting with
the cellular companies to ensure its continued use.
Have we lost our privacy by cell phone tracking or have we just gained a
valuable tool for law enforcement to use in keeping us safe? Do the cell phone
companies need to know where you are in order to provide their service, or have
they found, as some privacy advocates claim, a backdoor into your life, your
locations, your shopping habits?
Part One: Mobile 911.
According to the TechTV Show "Talkback", Cell phones show where you are, and
that is simply part of their design. Without the ability to pinpoint where the
signal from your phone is coming from, calls could never be connected. Because
cell phones decry the use of wires, and the users making the calls are often on
the move, the call and the receiving signal are not at a fixed location.
Therefore, the signal from the cell phone must be tracked.
Cell phone service areas are divided into "cells," each of which is serviced by
a base station. When you make a call, your cell phone selects the strongest base
station it can find, which is usually the closest station to you.
If you move out of the coverage of one base station, your phone switches to the
next strongest available base station (which usually means you move into a new
cell). The system always knows your location relative to the nearest cell.
This occurs even when your phone is on but not being used. For efficiency's
sake, an idle cell phone sends out a message on the access channel so that the
system will know where to direct the page if you get an incoming call. The
system knows where you are. In an urban area, each tower covers an area of
approximately 1 to 2 square miles, so a caller's general location is fairly easy
to pinpoint How to recover deleted messages.
The proliferation of cellular phones and their usage gave birth to a very unique
problem: How would emergency operators track callers who called 911 on their
mobile phone? Dialing 911 from a traditional, wire-based telephone, allowed the
operator to track where the call was being placed, so that an emergency response
could be sent. On mobile phones, the people calling in the emergency had no idea
where they were, and the 911 operators had no way of exactly pin pointing where
the calls where originating.
