Communication satellite systems
• 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.
Globalstar
Iridium
Teledesic
Inmarsat System
• Uses Geostationary satellites– Inmarsat uses four
geostationary satellites
– The satellites are in the same position relative to earth.
– They will always be seen in that position.

Using the ISDN3,1 kHz Audio Service
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
