Though we are late in setting up of the wireless mesh, which was due for over a year, we finally got a working free information network. We intend to create a community network in Mumbai that will spread from place to place to create a citywide people's network. People can use this network to publish useful content. To begin with it will serve all of wikipedia through the [http://www.gnowledge.org/ gnowledge.org protal] and lots and lots of useful free software for enabling the community. | ||
People anywhere in India or other places are invited to look at our community network, and replicate it in other parts of the world. We will periodically conduct workshops at the request of the community and will transfer the technology. We also request others to develop the skills and take it to every corner of the country, or rather every corner of the world. | People anywhere in India or other places are invited to look at our community network, and replicate it in other parts of the world.

Linksys WRT54GS V.4 Wireless Routers. This is used since we can add [http://wiki.freifunk.net/Freifunk_Firmware_%28English%29 freifunk firmware]. Freifunk site also lists few other routers. You can use any of them. Of course it is possible to create a wireless mesh using any PC with a WLAN card. | Linksys WRT54GS V.4 Wireless Routers.

A laptop or a PC connected to the mesh can also run OLSR daemon | A laptop or a PC connected to the mesh can also run olsrd (OLSR daemon available from download section of http://www.olsr.org/ for all the popular operating systems). This will make each of the PCs act as additional nodes of the mesh. This way the mesh dynamically changes its shape. During our experiment we added a GNU/Linux PC running PPC architecture and a MS Windows PC in the mesh after running the olsrd on each of them. | ||

About Rs. 3000/- for each wireless router. And another Rs.3000/- for a booster antenna, which is required only on those nodes which need to cross a large ground or large uninhabited area. And of course the spirit to share knowledge and your precious time. | About Rs. 3000/- for each wireless router.
