This policy brief explores the potential of community networks (CNs) as an inclusive, decentralised, and democratic response to the digital divide in urban areas. It draws on successful case studies from the Global South and North – specifically in Buenos Aires and New York City – to argue for their strategic value in promoting meaningful connectivity, community resilience, and digital rights. The brief highlights the need for the G20 to adopt regulatory, financial, and governance frameworks that support CN deployment, particularly in underserved urban contexts.
