2. Nato Satcom - TSGT T1 COG-99

3. 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

4. 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.

5. Spot Beam Fore the land masses and the coast, the spot beam coverage is almost total.

24. SECURE GSM/DECT OPTION: NSK 200 & Nera WorldCommunicator

25. PSTN NSK 201 DECT BASE STATION GSM NSK 200 NSK 200 GSM/DECT mobile phone NSK 200 GSM to GSM via GSM network GSM to DECT via GSM and PSTN network DECT to DECT via PSTN network

26. PSTN WorldCommunicator with new DECT module NSK 201 DECT BASE STATION GSM NSK 200 Nera WorldCommunicator with NSK 200 GSM/DECT mobile phone This is what Nera will offer NSK 200 Using the ISDN 3,1 kHz Audio Service

27. 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

28. DECT Development Today: GAP DECT standard only Will develope and implement the D2 data standard and analogue modem Keep all current DECT functionality Ready Q4 2002
