Globalstar Low Earth Orbit cell-phones added 10/15/01
http://www.qualcomm.com/globalstar/about/howitworks.html
The
QUALCOMM Globalstar GSP-1600 Portable Tri-Mode Satellite Phone works like a
cellular phone wherever cellular service is available, both in analog and
digital CDMA mode, and will switch to Globalstar satellite mode when the user is
out of cellular range, or when the satellite antenna is extended.
The GSP-1600 does work inside buildings when in cellular mode. However, in
satellite mode, the user must have direct line-of-sight with Globalstar
satellites, away from buildings or large structures.
How
long is the battery life?
In
Globalstar satellite mode, the GSP-1600 Portable Tri-Mode Satellite Phone has
about 3.5 hours of talk time and about 9 hours of standby time. Both times
should increase in capacity in the future as the system develops. When the phone
is operated in digital cellular mode, it has about 4.5 hours of talk time and 72
hours of standby time. In traditional analog mode, the phone has at least 2.5
hours of talk time and 14 hours standby time.
