2. CRIES • Role of satellite in Public Safety Wireless network • The assets of the satellite are numerous: • simple and fast • deploy a ground station and that’s it! • cheap and reliable • available everywhere • worldwide coverage including remote and out-of-way areas • broadband • from few kbps to tens of Mbps • mobile •  Satellites should play a central role in Public Safety wireless network

3. CRIES • Contents of the CRIES project • Three applications • Short term recovery of mobile communication in disaster area • to provide temporary GSM communications in disaster area on short notice • Broadband multimedia communication in emergency situation • to provide temporary broadband communication (DVB, Internet) in operation areas (overseas theater) • Retrieval and broadcasting of data • to provide continuous or temporary collection of scientific and logistic data.

CRIES • Principle of the CRIES project • It is a joint research project on techniques and technologies for wireless and satellite communication networks • To federate the research effort of an European team of • Industrials, research centers, universities... • To identify, study, develop and promote innovative techniques • for public safety uses, but also • for commercial uses (higher ROI) • and why not: to contemplate standardization

5. CRIES • Reasons of the CRIES project • To identify, study, develop and promote innovative techniques & technologies for wireless and satellite communication systems in all domains • Why targeting Public Safety applications ? • Challenge: mostly Public Safety networks require innovative and performing techniques • Reasonable scale: Implementation remains in a small scale (capacity, size and cost) • Political support • Submitted as an Expression of Interest to the European Union in the frame of the 6th PCRD

6. CRIES • Contents of the CRIES project • 1.. Short term recovery of mobile communication in disaster area • 2.. Broadband multimedia communication in emergency situation • 3.. Retrieval and broadcasting of data

7. HAPHAZARDS • System for short term recovery of • mobile communication (GSM) in emergency • During disasters or in emergency situations, mobile networks are damaged or saturated, unluckily it is the time when they are most craved for. • Mobile phone helps to coordinate rescue effort • Mobile phone bridges stricken population to the rest of the world (news, family contact...) • Roaming phones could locate victims • The goal of the system is to replace or add phone capacity in the zone of disaster on a short notice for several hours.

8. HAPHAZARDS Geostationary communication satellite over Europe HAPS for emergency situation Gateway station somewhere in Europe Rescuer / victim mobile phone Altitude 3...20 km Fixed segment of mobile network Disaster area ( Ø 1...150 km)

9. HAPHAZARDS • HAPHAZARDS (High Altitude Platform for Hazard Situation) • Special designed aircraft circle above disaster area and are equipped with communication payload. • The communication payload relays GSM phone signals from disaster area toward a gateway connected to the public telephone networks. • The connection is made via a geostationary satellite • The airborne communication payload includes • a base transceiver station with a smart antenna pointing to the disaster area • a satcom terminal pointing to the satellite.

11. HAPHAZARDS • Enabling techniques • Smart antenna and SDMA • pointing accuracy (compensation of aircraft movement) • beam forming for cellular coverage • minimization of interference (cohabitation with existing GSM network) • frequency re-use to increase capacity • Airborne SATCOM terminal • Radio-localization • Aircraft techniques • unmanned autonomous aircraft • power supply

14. ESSENCE • System for broadband multimedia communication • in emergency situation • During emergency or crisis times, providing broadband communication is necessary but a difficult challenge • broadband ground networks are not fully available (destroyed, non-existent, unreliable, corrupted…) for establishing: • links with Europe or overseas decision making centers • links inside the theater of operations • The goal of the system is to provide broadband capacity with high mobility in the zone of operation for a limited time. • intended to governmental and institutional use • an operation zone of about 1000 km wide everywhere in the world.

16. ESSENCE • ESSENCE (European Satellite System Establishing Networks for Communications in Emergency) • Special designed satellite payload as a piggy back on a geostationary satellite working in the Ka frequency band (30/20 GHz) with On Board Processing. • Intended for a governmental or institutional use within an operation zone (1000 km). • Special designed portable terminals for roving use • Easy to use (automatic pointing and log-on) • Transportable (small, compact, light and robust) • Reliable • Transportable terminal for fixed use • transportable and low cost

17. ESSENCE Roving terminal Laptop computer 40 cm Radome Source, RF front end, modem 60 cm Ethernet cable or Wireless IR Battery Weight < 10 kg

18. ESSENCE • Missions and services • Technical challenges • Use of compact and power limited terminals • Quick deployment • Cohabitation with existing systems (interference and compatibility) • Good quality of service (data rate and availability) • Services • DVB-S data and video broadcasting @ up to 27 Mbps • InternetAccess: forward link @ 64 kbps to 27 Mbps, return link @ 16 kbps to 256 kbps. • Peer to Peer bi-directional links: LAN interconnection, NetMeeting, Voice on IP… @ 64 kbps to 2048 kbps.

24. Satellite based system for retrieve and diffusion of monitoring and scientific data • In disasters areas or remote areas, it could be interesting to monitor and to gather scientific, medical and technical data from remotely controlled and autonomous stations. • The goal of the system is to connect through a geostationary satellite, small remote controlled stations to the Internet. Each station has its own IP address and is accessible by means of a client/server mechanism from a PC anywhere in the planet. • Based on DVB-RCS and DVB-S, SNMP, TCP/IP

26. CRIES • Conclusions • The CRIES project could federate research efforts on the challenging mission of Public Protection Disaster Relief. • The CRIES project addresses PPDR aspects where satellite is the more valuable tool (communication). • The CRIES project should require an important effort of standardization to gain the adhesion of all actors in PPDR • The CRIES project could latter result in operational PPDR systems for the good of everybody (God willing!). • Alcatel Space is seeking European partners to promote this project. • Thank you for your attention...
