11. Inexpensive

12. High Performance

13. Uses two Linksys WRT54G Wi-Fi Routers

14. Uses DDWRT Firmware for more flexibility

15. One in AP Mode with 8dBi Panel Antenna

16. One in Repeater Mode with 19dBi Parabolic Antenna ¼ Mile Link

17. VOIP Enables Free Voice Calling Allows the communication node to become a wireless phone booth Utilizes Google Voice for free incoming calls VOIP Server VOIP to Analog Phone Adapter

18. Innovative Applications Third World Rural Locations Extend Internet connectivity from urban areas to rural areas Connect villages together

19. Innovative Applications National Parks Provides up-to-date weather and trail information Many parks do not provide reliable cell phone coverage Hiking fatalities can be prevented by alerting hikers of potential trail and weather danger

20. Innovative Applications Disaster Recovery Quickly deployable and inexpensive communications network Self sustainable –> no need for diesel generators or any other infrastructure that could have been destroyed

21. Team Work Key to Project’s Success Dan is very knowledgeable of wireless communications and networking Dave is knowledgeable of embedded and high-level programming for the microcontroller and server Worked together extensively to solve the mechanical and electrical aspects of the project
