Creating digital networks is mostly a social process.!
Key Aspects: Social & Technical Infrastructure ! • Main network anchors are trusted community organizations.! • Solid relationship with technical support provider from outside of the community.! • Community-led design process emphasizes local needs and enhances engagement.! • Rapid prototyping of applications designed for the local area network. !
Lessons Learned! • Social relationships are paramount.! ! • The most chal enging 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 smal 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.!

Cost of the Network! • Donated labor from local residents and technologist. ! • Institutional support from RHI and OTI. ! • Hardware (~$50 to ~$85 each router). ! • Instal ation (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. !
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 The bandwidth delivered to the end user can be up to 50 Mbps, but is (point-to-point wireless or fiber-optic backhaul, white dependent on available bandwidth at the gateway connection. There are space device, etc.) various models for determining how many users can share a given connection. Each user-facing access point can support up to 25 (5 to 10 units) Gateway distribution layer simultaneous connections, but speed will depend on available Point-to-point or -multipoint directional mesh bandwidth at the gateway, interference, and other factors. Engineering wireless nodes. study is required to determine the technical feasibility of each tile. Community participation is key in determining rooftop anchor sites and (25 to 100 units) User-facing access points pilot "early adopter" candidates. Omnidirectional mesh wireless nodes mounted on lightpoles, building exteriors, rooftops, or windows. Hardware = approximately $25,000 Installation labor = approximately $75,000 to $150,000 Wired connection Wireless connection
