1 Terrestrial Microwave Data Network WiFi Emergency Wireless Network WiFi in the context of RACES

2 Overview EWN History (Brief)! The Technology (In Context)! Complexity (The Enemy)! Higher Level Design! The Role of RACES

3 EWN History Reasons! When RACES Shows Up To An Incident - We have PTT, We have Packet! We must have better toys than they have if we want to add value! Merge Government & Corporate Strengths! Started in late 2005! 2004 Tsunami & Katrina! Non-profit - could carry no weight! for-profit - SLAs, value! no-one wanted to talk to government!

4 Technology Voice Radio! 25 word message - 3 to 5 minutes on a quiet channel

5 Technology (Cont.) Packet Radio! 25 word message - 10 seconds! Text only - no MS Office tools! Size Limits! The Served Agency s Tools! PacForms is a protocol - use tags

6 Technology (Cont.) APRS! Provides a shared distributed blackboard! All disasters are local - with local resources & constraints! Safety of deployed personnel

7 Technology (Cont.) Part15 v.s. Part97! Cost & Complexity! Message Security! Public doesn t care Part15/97! We shouldn t be defending Part97 while the ship is sinking

8 Technology (Cont.) MESH v.s. Point-To-Point! MESH!= Magic! Perfect for Ad Hoc Networking! MESH as a leaf network not core! No more than 3 MESH hops before a non-mesh node

9 Technology (Cont.) Adaptable Networking! Hi-Gain to Omni! 3-4 mile radius line of sight

12 Complexity (Cont.) Complexity Is The Enemy! Complexity is Fragile & Expensive! The Internet v.s. Your HT! Complexity is a relative term

13 Complexity (Cont.) Complexity Will Be Managed Over Time! Complexity gets encapsulated into building blocks! The Internet Of Things: Embedded Linux - Not Windows

14 Complexity (Cont.) VoIP over WiFi v.s. Simplex Voice Channel! We must wrap our operations plan around new capabilities! Do not let the fear of complexity stop the correct solution: Manage It

15 Higher Level Design Plan For Failure!! We Need To Plan For A Graceful Degradation In Services! WiFi -> Packet -> Voice

16 Higher Level Design (Cont.) VoIP Phones! Network Printing! Anonymous FTP! Walled UseNet NetNews Servers w/web Interface - ICS Newsgroups! Replicated Wiki Servers! Map Server - OpenStreetMaps! Sahana! TicketsCAD/MDB! APRS/Xastir

17 RACES Role in the Future Can t do SLA s & Daily deployment! Local FD s R&D Dept.! IT Infrastructure at the ICP! Preserve a Mobile/Distributed EOC Capability

18 RACES Role in the Future (Cont.) EWN Structure in RACES! Local RACES Groups - Intracity Comm! Non-profit umbrella group - Inter-city links
