Communication satellite systems
Globalstar
Teledesic
Iridium
• Satellite systems
such as Iridium and
Globalstar use Low
Earth Orbit satellite
which move very fast
over the sky, which
require many
gateways or a
complicated switch
over system between
satellites.

– Inmarsat uses four
geostationary
satellites
– The satellites are in
the same position
relative to earth.
– They will always be
seen in that position.
Spot Beam
Fore the land masses and
the coast, the spot beam
coverage is almost total.

Why the Satellite option?
• Gives user access to other GSM encrypted devices when
GSM or terrestrial lines are unavailable
• No external devices needed - DECT base station is
integrated in the WorldCommunicator. The battery in the
satellite terminal has over 50 hours standby time and
several hours talk time.
• Connectivity - one handset, one phone number, one
phone book and one crypto key no matter what service
you use (GSM, DECT/Terrestrial or DECT/Satellite)
– You simply forward your calls to the service you are using
DECT Development
• Today: GAP DECT standard only
• Will develope and implement the D2 data
standard and analogue modem
• Keep all current DECT functionality
