1 GSM to Satcom - NSK 200 over Inmarsat Presented by Torgrim Jorgensen Presented by Torgrim Jorgensen

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.

6 Inmarsat GAN coverage

7 Nera WorldCommunicator

8

9 Main elements portable antenna

10 Main elements fixed antenna

11 GAN Services 64 kbps speech 4,8 kbps speech (low cost) MPDS - Mobile Packet Data System 64 kbps data UDI 56 kbps data 64 kbps audio (3.1kHz analogue) All services gives full Duplex

12 Interfaces ISDN –Connector RJ-45 –Standard Euro ISDN(DSS1), NI-1 (US) RS-232 –9 pin DSUB, DTE –Bit rate ( bps) USB (Universal Serial Bus) –Upstream connector Built-in DECT base station –Wireless up to 300 meters –GAP standard Secure voice STUIII / STUIIB

13 Telephone connections Each telephone can have separate IMN 1 external and “3” internal calls at a time Different call quality: –4.8 Kbps speech –64 Kbps speech Max 12 DECT Max 8 ISDN

14 Internal & External calls Transfer and park incoming calls Grouping of all DECT handsets to one IMN Grouping of all ISDN to one IMN Grouping of one DECT and one ISDN to one IMN

15 Data connections ISDN USB RS kbps data 56 kbps data 64 kbps audio 64 kbps data MPDS Vt-lite Software download 64 kbps data MPDS Vt-lite

16 Power input / consumption DC Input to Modem –19VDC AC/DC Adapter –100 to 240V AC DC/DC Adapter –10 to 32V DC Consumption –Transmit: 32 W –Standby: 0.75 W –Charging: 30 W maximum

17 Battery life time Standby time –>50 hrs. 4,8 kbps voice –4,5 - 9 hrs. 64 kbps voice –3 - 6 hrs. 64 kbps data – hrs

18 Size and Wight Dimensions collapsed: –H=68mm W=260mm D=355mm Antenna folded out: –H=340mm W=774mm D=10mm Weight: –4,2 kg (with battery) –3,7 kg (without)

19 Environmental conditions Operational –Antenna: -25 to +55 o C –Modem:-25 to +55 o C Storage –-50 o C to +80 o C IP grade –Antenna IP55 –Modem IP53 Robustness –0.8 m drop on concrete

20 Applications for NWC Data, Dial up networking Video conference Video store & forward Video Surveillance Audio Voice SCADA Fax G3 and G4 Multiplexers Encryption Devices

21 Mobile Packed Data System MPDS

22 Features Pay for data used, not per minute Users share 64 kbps channels “Always on” - keep connected at no additional cost. Access to the world-wide WEB Immediate transfer On-line SCADA applications Reduce costs for specific applications

23 Typical Applications Internet/intranet Map updates Database queries SCADA Status/diagnostics

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

29 NSK 200 connection at present NSK 200 NSK 201 DECT base station Terminal Adapter Nera WorldCommunicator

30 Nera F77 Continuing the Saturn tradition

31 Nera F77 services 4,8 kbps voice (low cost) 64 kbps speech 64 kbps data / G4 fax 56 kbps data 3.1 kHz audio MPDS MobilePackedDataService All services gives full Duplex

32 Nera F77 on German Fregate

33 PSTN NSK 201 DECT BASE STATION GSM NSK 200 NSK 200 at sea! This is what Nera can offer NSK 200 NSK 201 DECT BASE STATION Nera F77

34 Other crypto solutions

35 WorldCommunicator and IP encryption Router IP encryption (TCE 621) PC Nera WorldCommunicator

36 WorldCommunicator and PACE Nera WorldCommunicator DECT PACE ISDNPACE 64 kbps voice
