Satellite Messaging Overview

Exciting Satellite Receiver Technology

The Iridium satellite system is a revolution in
wireless communication technology. Satellites that
circle the earth keep you in constant
communication. Together with Iridium WorldPage
service, Motorola's 9501 pager offers the first true
global roaming capability in a small belt-worn
personal message receiver. While it offers the best
in paging features, the 9501 does not operate like a
typical pager.

Receiving Satellite Signals

Most pagers receive messages transmitted from
towers on the ground. The 9501 pager receives
messages transmitted directly from satellite. This
can be more difficult, in some instances, due to the
distance the signal must travel from space.
With most satellite-based communication, such as
satellite TV or the Global Positioning System (GPS),
a satellite dish or hand-held unit must be positioned
outside of buildings to receive information. However,
with Motorola's Satellite Series 9501 Pager, you can
now receive messages inside buildings.
In some environments, the message signal
Note :
may be effectively blocked, preventing
reception. The ability to receive messages in
the interior of large urban buildings will be
particularly limited.
