[Hidden-tech] Verizon vs. AT&T coverage

[ussailis at shaysnet.com]

Much of the difference between cell providers is in the 'Sim' chip in your
phone. There the cell towers that can be accessed are registered. 

The problem is many cell towers / cell sites are privately owned, that is
not owned by the 'big boys' in the cell service business. So the card (and
I suppose your plan) tells the phone where to connect.

Another issue is there are two frequency bands, around 830 to 860 MHz and
around 1850 MHz. These bands have somewhat different propagation
characteristics which can reduce signal effectiveness. I suspect, but could
be wrong, that Verizon uses the lower frequency band.

There are also differences in the quality / effectiveness of the various
phones. Some are not as well engineered as others. 

The short of it is your coverage might be different than someone else using
the same service.

If you are concerned about radiation from a cell tower, you should consider
your microwave oven a worse offender. It operates at 2450 MHz +/- 50 MHz
and is allowed to leak a tiny amount of power which is more power than you
will receiver from the cell tower. The reason for this is simply you are
much closer to the microwave than you will ever get to the cell tower
antenna.

Although it radiates only a watt or two, you receive far more radiation
from a cell phone handset than anything else, because you are so close to
it.

Late model cell phone handsets should radiate less toward your body than
older phones because standards have been set and manufactures have designed
the phones to radiate less toward the user.
