  1. GSM to Satcom -NSK 200 over Inmarsat Presented by Torgrim Jorgensen tj@satcom.nera.no

  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 Teledesic Iridium

  4. 178º E Pacific Ocean Region 35700 km Indian Ocean Atlantic Region Ocean Region West 55º W Atlantic Ocean 64º Region East 15.5º W 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. Nera WorldCommunicator

  9. Main elements portable antenna

  10. Main elements fixed antenna

  11. 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) GAN Services All services gives full Duplex

  12. ISDN Connector RJ-45 Standard Euro ISDN(DSS1), NI-1 (US) RS-232 9 pin DSUB, DTE Bit rate (1200 - 115000 bps) USB (Universal Serial Bus) Upstream connector Built-in DECT base station Wireless up to 300 meters GAP standard Secure voice STUIII / STUIIB U S B I S D N R S - 2 3 2 Interfaces

  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 USB 64 kbps data MPDS Vt-lite RS-232 ISDN 64 kbps data MPDS Vt-lite Software download 64 kbps data 56 kbps data 64 kbps audio

  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 • 1.5 - 3 hrs

  18. 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) Size and Wight

  19. Environmental conditions • Operational • Antenna: -25 to +55oC • Modem: -25 to +55oC • Storage • -50oC to +80oC • 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 SystemMPDS

  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 e-mail transfer • On-line SCADA applications • Reduce costs for specific applications

  23. Typical Applications • E-mail • Internet/intranet • Map updates • Database queries • SCADA • Status/diagnostics

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

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

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

  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
