  22. 22. Lessons Learned! •  Social relationships are paramount.! ! •  The most challenging investment is in the initial organizing and design phase before any value is realized. ! ! •  Community-designed applications add value to a local network, even at a small scale. ! ! •  Having relationships and anchor wireless nodes in place prior to a disaster facilitates rapid network deployment through: ! –  Already-established relationships with key community stakeholders.! –  A heightened level of technological literacy in the community.! –  Pre-positioned wireless network equipment in the neighborhood.!
  23. 23. What’s Next?! texting   sensors   outreach   apps  
  24. 24. Additional Materials!
  25. 25. Cost of the Network! •  •  •  •  •  •  Donated labor from local residents and technologist. ! Institutional support from RHI and OTI. ! Hardware (~$50 to ~$85 each router). ! Installation (3-5 work hours for two people per site). ! Bandwidth (donated by RHI, Brooklyn Fiber, and FEMA). ! Training program for local residents to maintain and expand network as part of a municipal employment program. !
  26. 26. Modular mesh wireless tile People in or next to the tile area can extend the network by installing their own routers. 1/2 to 3/4 mile (1 unit) Internet Gateway Connection to the global Internet or point of presence (point-to-point wireless or fiber-optic backhaul, white space device, etc.) (5 to 10 units) Gateway distribution layer Point-to-point or -multipoint directional mesh wireless nodes. (25 to 100 units) User-facing access points Omnidirectional mesh wireless nodes mounted on lightpoles, building exteriors, rooftops, or windows. Wired connection Wireless connection The bandwidth delivered to the end user can be up to 50 Mbps, but is dependent on available bandwidth at the gateway connection. There are various models for determining how many users can share a given connection. Each user-facing access point can support up to 25 simultaneous connections, but speed will depend on available bandwidth at the gateway, interference, and other factors. Engineering study is required to determine the technical feasibility of each tile. Community participation is key in determining rooftop anchor sites and pilot "early adopter" candidates. Hardware = approximately $25,000 Installation labor = approximately $75,000 to $150,000
