Community networks are a reality all over the world. Beyond presenting them as alternatives to "connect to the disconnected", this article intends to describe how these initiatives have organized themselves to invent their own ways of "connecting themselves", shifting the discussion about the provision of Internet access to the Internet in defense of technological solutions adapted for the exercise of local and global freedom of expression. Based on the experience of CooLab and the Brazilian Digital Radio Association, both collectives dedicated to the construction of autonomous communication infrastructures, the intention is to develop a reflection on the importance of fostering community networks taking into account the principle of complementarity present in Art 223 of the Brazilian Constitution, from a theoretical perspective of creation of a public sphere where commercial, public and community infrastructures coexist, putting emphasis on the public debate that emerges from autonomous infrastructures of communication. Presenting both low-cost equipment and new production tools for local circulation of content, the proposal is to describe the differentiated techno-aesthetic, technomagic teaching-learning method, opposing it to the connectivity indexes, discussing the effective construction of diverse cultural sensibilities use of technologies. Finally, it is intended to argue in defense of the Digital Radio Mondiale standard as an alternative to the Brazilian Digital Radio System in Brazil highlighting its potential for convergence with digital TV and the internet through the Ginga middleware, which allows different levels of interactivity and the creation and sharing of applications and content between major territories and overseas.
