  2. Agenda The Need Uniqueness Recognition How it works The Potential

  3. Due to the Tsunami 2004 Sri Lanka lost more than 35,000 lives unnecessarily. Most of the development activities were put on hold due to the destruction. Countries economic system was set back by years. The Need of Early Warning

  4. Conventional Early Warning Methods TV Radio Satellite Radio HF and VHF radio networks Mega Phones Temple/Church Bells Etc.

  5. The Uniqueness of DEWN Effective in alerting citizens at day or night Immune to communication network congestion Comprehensible in terms of local dialect Directed to specific location or person or equally applicable for mass dissemination

  6. The Uniqueness of DEWN Contd. Affordability Can be accessed even through low cost handsets Accessibility Through mobile phones as well as alarm devices Availability Anywhere within a GSM or 3G coverage

  7. Recognition

  8. Dialog Telekom’s DEWN is an integrated disaster and emergency warning network that incorporates network based as well as device based technologies to deliver an end to end disaster warning solution through the centrally configurable carriage and dissemination of alerts Disaster Management Centre (DMC)

  9. SMS for limited/selected recipients Cell broadcasts for mass alerting even under conditions of network congestion Location based cell broadcast and location directed SMS Network Technologies

  10. Unique delivery methods to close the loop between dissemination and effective interpretation SMS and CB messages in to screen flashes and audible alarm Handset resident applications Tri-lingual from encompassing Sinhala and Tamil Delivery Methods

  11. Delivery Methods Contd GSM DEWN Alarm Device High volume alarm Alarm Lamp Inbuilt radio which can be tuned remotely Interface to domestic devices (temple/church bells, loudspeaker systems)

  12. Message authenticity verification and multiple key verification Anti-spam protection Database technologies for location, group or individual directed messaging SMS/voice based call back Administration and control front end for centralized management Process Technologies

  13. The authorized body to disseminate disaster related info in Sri Lanka Disaster Management Centre How DEWN Works Meteorological Department Department of Irrigation National Building Research Organization World Meteorological Organization USGS Hawaii

  14. Execution Flow

  15. Execution Flow Disaster Information Dissemination

  16. How DEWN Works

  17. Terminal resident warning application Customizable and situation specific presentation Downloadable over GPRS Special alarm tone Java/Symbian Handset

  18. Multiple wake-up measures Power source compatibility Backup power Multiple alarm interfaces GSM DEWN Alarm Device

  19. GSM DEWN Alarm Device Architecture

  20. Immune to network congestion Ideal for mass alerts Configure by location specific basis Cell Broadcast and Mass Alerts

  21. Cell Broadcast Dispatch of messages to the masses at an instant within a geographic area. Geographic area is controlled via the BSCs and cell where the broadcasting will take place

  22. UoM lab “The Dialog-University of Moratuwa Mobile Communication Research Laboratory is proud to be a partner in this innovation which has the potential to save thousands of lives”

  23. Info dissemination Hierarchy/levels

  24. Instant Alerting Mass and Directed Dissemination Wide Availability Affordability Applicability and effectiveness Reliability and authenticity Scalability DEWN – The Potential

  25. DEWN – The Potential Applicability of DEWN in other natural or manmade disaster situations Flood, Cyclone Dam Burst Epidemic Forest fire Bomb explosion, Chemical attacks

  26. DEWN – The Potential Inclusion Converting a GSM mobile phone to an affordable alarm terminal within the national disaster warning infrastructure. The rapid growth of mobile network coverage around the world will catalyze the inclusion
