Wireless Technology Solutions to Social Problems Funded
Vodafone Americas Foundation: Wireless Innovation Project
The Vodafone Americas Foundation’s Wireless Innovation Project supports exemplary wireless-related technology innovations that address critical social issues throughout the world. Funded projects should present a solution to a clearly defined social problem within the areas of education, health, access to communication, environment, or economic development. Applicants must be part of an established multi-disciplinary team that provides the expertise needed for a comprehensive solution to the targeted problem. The Wireless Innovation Project will provide up to $600,000 for projects from universities and nonprofit organizations based in the United States. (Although organizations must be based in the U.S., projects may operate and help people outside of the U.S.) Winners will be selected for awards of $100,000, $200,000, and $300,000, which will be paid in equal installments over three years. The application deadline is February 27, 2015. Visit the Vodafone Americas Foundation website to take the required eligibility questionnaire and submit an online application.
