Conventional Early Warning Methods
The Uniqueness of DEWN
Effective in alerting citizens at day or nightImmune to communication network congestionComprehensible in terms of local dialectDirected to specific location or person or equally applicable for mass dissemination
The Uniqueness of DEWN Contd.
AffordabilityCan be accessed even through low cost handsetsAccessibilityThrough mobile phones as well as alarm devicesAvailabilityAnywhere within a GSM or 3G coverage
Recognition
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)
Network Technologies
SMS for limited/selected recipientsCell broadcasts for mass alerting even under conditions of network congestionLocation based cell broadcast and location directed SMS
Delivery Methods
Unique delivery methods to close the loop between dissemination and effective interpretationSMS and CB messages in to screen flashes and audible alarmHandset resident applicationsTri-lingual from encompassing Sinhala and Tamil

Cell Broadcast and Mass Alerts
Immune to network congestionIdeal for mass alertsConfigure by location specific basis
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
