COG-99

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
