| Satellite cell phones are
mobile phones that communications directly with satellites,
rather than going through normal cellular networks. Communication
is established using a large rectangular antenna that is built
into each phone. Although quite bulky in appearance satellite
cell phones are still small enough to be transported fairly
easily.
The main advantage of satellite phones
over normal cellular technology is that they can theoretically
be used anywhere in the world, no matter how remote the location.
This is due to the fact that they receive their signals from
orbiting satellites, not fixed-location cell phone towers.
