16. WIDER3 wireless solution Access Points in the camps Point-to-Multipoint Open WiFi access near the central unit WiFi in Disaster and Emergency Response

17. Proposed wireless solution WiFi in Disaster and Emergency Response

18. New System Services Caching Server NAT & Firewall GSM Connectivity Central Database Management System WiFi in Disaster and Emergency Response

19. Caching Server Concept WiFi in Disaster and Emergency Response

20. Caching Server Operation WiFi in Disaster and Emergency Response

21. Caching Server Features Improvement of the response time for Internet objects Optimization of the satellite’s bandwidth usage Authentication for Internet access Bandwidth management Black list implementation Protection to the internal hosts by proxying the traffic WiFi in Disaster and Emergency Response

22. Caching Server Parameters Hit ratio from 30 to 60% Byte hit ratio from 20 to 50 % Number of users – The less users, the lower efficiency Type of traffic – Cacheable/Non cacheable – Traffic Likelihood Cache size – The bigger cache, the higher hit ratios WiFi in Disaster and Emergency Response

23. NAT WiFi in Disaster and Emergency Response

24. Firewall WiFi in Disaster and Emergency Response

25. GSM Connectivity WiFi in Disaster and Emergency Response SIP server – AXD 320 – Fully functional AXD 320 – MSC – MSC not configured. Outside project scope.

26. Central Database with LDAP WiFi in Disaster and Emergency Response Facilitation of user administration Services using Central Database for authentication – RADIUS (Network access) – Caching server (Internet access) – Instant Messaging server – FTP server Database searchable with MS Outlook

27. System Management SerWeb WebMin Adminstrator and User Front-end WiFi in Disaster and Emergency Response

28. Conclusions Goals Achieved All primary goals were fully achieved – Extensive Wireless technology report – GSM connectivity – Caching server, Firewall & NAT First secondary goals was fully achieved – PEAP, Central Database, Front-end Secondary secondary goal partially achieved – L3-switch QoS configuration WiFi in Disaster and Emergency Response

29. Future Work Implementation of new wireless technology – WiMax – Meshed Network Extensive system testing LDAP authentication for SIP server MMS/SMS WiFi in Disaster and Emergency Response
