This chapter develops a perspective on peer-to-peer engagements on the coded city by analysing how coding practice is related to the development of other social and cultural 'codes' that propose alternative ways of integrating technology into space. It argues that peer-to-peer coded cities are most significant because they suggest alternative ways of governing the interface between technology, the social and the spatial. The chapter identifies how information and communications technology (ICT) projects of the past were imagined as providing opportunities for collaborative development and governance of particular urban spaces, in opposition to top-down efforts at urban communication governance taking place at the same time. Community wireless networks (CWNs), based on local experimentation with wireless radio technology, and emerged around the world in the years following the drop in price of radio communication equipment that used unlicensed or license-exempt radio, which could be reconfigured using free and open source software (F/OSS).
