This is a research about radio community in peripheral areas. We have chosen two radios: Novos Rumos, in Queimados, and Onda Livre, São João de Meriti, both located in a region called Baixada Fluminense. Due to a proliferation of radios in the last years in Brazil and the large debate about their regulation, it is important to understand their practice. Our goal is to achieve a better understanding of the motivations and strategies for the implementation of a radio community. How they are articulated to the local life and what is the meaning and the challenges for the construction of a radio community, considering marginalized areas, where authoritarian political practices area common.
