I found this interesting site about community wireless providers – defiantly one of the interested readings at last time.
I recommend to take a look at http://www.cwirp.ca/
The Community Wireless Infrastructure Research Project (CWIRP) project brings together an interdisciplinary team of academic researchers and community and government partners to engage in in-depth case studies of public/community-based ICT initiatives in order to document and assess the various models, best practices and benefits of public ICT infrastructure provision in Canada.
