Wireless for Communities (W4C) - Networking Basics

To help address the gap in last mile Internet connectivity for underserved communities, the Wireless for Communities (W4C) initiative was co-launched by the Internet Society and Digital Empowerment Foundation (DEF) in October 2010. The project involves deploying line-of-sight wireless technology and low-cost Wi-Fi eqipment which utilize the unlicensed 2.4 GHz and 5.8 GHZ spectrum bands to create community-owned and operated wireless networks. To further localize the initiative, the project was used to strengthen grassroots expertise by training community members in wireless technology, enabling those in the field not only to run and manage these networks but to transfer knowledge to others in the community. This is achieved through a Training of Trainers programme which has employed content developed by the Internet Society and DEF.

The W4C programme has expanded tremendously over the last couple of years, and the Internet Society in conjunction with its partners, is now looking to further scale to broader communities. On one hand, we have adapted the Train the Trainer materials into an online course which can be delivered via the organization's learning platform Inforum to prepare individuals to undertake the fieldwork associated with deploying community wireless networks. Simultaneously, we are making the same materials available to other communities for strictly capacity building or workforce skills development purposes.

The tutorials on this page cover the Network Basics modules of the Wireless for Communities (W4C) course.

If you are interested in partnering with the Internet Society to deliver the entire Wireless for Communities (W4C) course in a moderated format, please contact us at learning@internetsociety.org.
