Press Release Summary: This is basically a system to locate the handheld when making
a call to 911. In the mid to late 1990\'s, many people got cell phones just for the
emergency use of being able to call for help almost anywhere. The problem came up
when statistics showed that almost 92% of all serious 911 calls, (where the person
was just barely able to make the call), they either didn\'t know where they were or
was unable to tell the 911 operator where they were, or they might not have been
able to talk at all. This caused a big concern, 911 operators couldn\'t do anything
but listen to the person on their cell phone as they pass away. The Location
Sensitivity system still doesn\'t work if you are in an area that only has an analog
signal. (Which is the older cellular system of the mid 1990\'s and earlier). Most
metropolitan areas and all interstate freeways are covered by the newer digital
service. It\'s just when you get out in the middle of no-where, you might end up with
an analog signal. Most phones will display the letter \"A\" in the top right or left
corner when using this system. Check your phone documentation; some phones don\'t
even have this capability. Which means if you get into one of these areas, you can't
make any type of call what-so-ever?
Soon, the Location Sensitivity feature will probably be offered by the cellular
companies as part of their pricing plan. Some carriers like Nextel are already
taking advantage of this new technology by giving customers a GPS location service
along with their calling plan. If you don\'t have this option with your carrier, and
you have a Smartphone you can always purchase one of the SD slot GPS units that
works with mapping software. The program I\'ve really enjoyed is Mapopolis, which
works great with most of the popular GPS hardware available. And most even have a
voice activation that will tell you where to turn, which is directed through the
speaker phone portion of the Smartphones. The ability to have GPS information and
mapping on your handheld will be a great plus while traveling.

Back to the Location Sensitivity. I\'m just wondering how much the cellular companies
are going to charge for such a GPS type service!? I\'m sure they\'re all working hard
right now on the new pricing plans that we\'ll have to pay if you don\'t have the GPS
hardware to install on your Smartphone.

When these services become available, they will only be location based. Another
words, most GPS\'s these days will actually give you your current altitude and most
have a pretty fast refresh rate. The refresh rate is the time between position
updates. An example; If you have a GPS in your hand that refreshed three times per
second, this would be a very actuate reading. Even if you are driving at 70 miles
per hour, the moving map on the GPS will be able to keep up with your actual
location. That\'s an issue the engineers are dealing with on the Location Sensitivity
system. It wasn\'t designed to have any type of refresh rate at all. Once a position
has been found, it never was designed to refresh that position. (I guess if you are
hurt, and you called 911, you aren\'t supposed to be moving. Hmmm, So if you fell off
a bridge, and landed in the back of a truck driving down the interstate, I\'m not
sure if they would be able to locate you. They would know where you were when you
first dialed 911, but as your location changes, they might not be able to find you).
Supposedly, the 911 operator can pull a refresh; this would at least tell them the
direction the vehicle is moving. But to locate you while you\'re moving might be more
difficult than anyone had expected.
Another problem with many of the handheld units, the actual speed of the processors
within them. Most cell phones operate on around 1 to 2 MHz processor speed. Most
Smartphones operate anywhere between 30 to 500 MHz (Most new home computers are
operating between 2 to 4 GHz processor speed, just to give you an idea). This is
where the engineers are running into the biggest problem with creating a GPS refresh
rate. The processors in all handhelds will just have to be faster than they are
today. And like all of our other technologies, I\'m sure this won\'t be a problem very
much longer for the designers.
Hmmm, soon we\'ll have Pentium 9 cellular and Smartphones running at 8 GHz processor
speed! You know it\'s going to come to this, and it\'s not that far away.
