In most middle- and upper-income homes across the United States, children, youth, and their families have access to the world's information-technology resources at their fingertips, while in low-income communities, access to technology and the opportunities it provides are often limited to brief periods of computer use and Internet access at school or at the public library. Technology for All (TFA) is a non-profit organization whose mission is to use technology to address the disparity of opportunity that exists in the cities' low-income neighborhoods. By working with local community-based organizations, corporations, foundations, technology providers, and public entities, TFA creates educational, economic, and personal opportunities for low-income persons and the communities in which they live. TFA and Rice University have partnered to design, build, and deploy a multihop wireless network in some of Houston's most economically disadvantaged neighborhoods where per-capita income is approximately one-third the national average and 36.7 percent of the children (under 18) live below the poverty line according to the 2000 U.S. Census. This article describes how TFA and Rice University have developed and deployed multihop wireless networks for low-income communities in Houston. (Contains 3 figures and 5 footnotes.)
