Community Wi-Fi network even uses satellite dishes
“Among the most popular attractions of this year’s CAFECONF 07 Linux conference down in Argentina, the “Buenos Aires Libre” group, is promoting its hobbyist, city-wide “community network”. B.A. Libre aims to run a network with its own backbone, capable of routing traffic between nodes even if the Internet goes down, it doesn’t rely on the public internet for transportation. The project was kick-started by a handful users a long six years ago and after several iterations and change of structure and leadership, now seems to show steady progress. The BAL network spine uses point-to-point links and directional antennas along with inexpensive consumer Wi-Fi APs or in some instances full PCs in waterproof enclosures- loaded with their own customized Linux software, dubbed Obelisco – Spanish for ‘obelisk’ the city’s landmark. I asked them if they had any run-ins with the airwaves watchdog and their response was an emphatic no. There’s a regulation making selling VOIP or telephony services using Wi-Fi equipment strictly and specifically forbidden by the airwaves watchdog, but it’s aimed at ISPs. First BAL is a non-profit endeavour, a community network, and it doesn’t aim to provide any specific services, just inter-connect computers. Thus the local regulating authority gives them no hassle at all because such non-profit usage falls within the ‘private use’ considerations of the local regulations. On the software/organisation aspect, they have done a quite impressive job. The Wiki shows a lot of work, and there’s even an on-line map built using Google Maps satellite images and showcasing all nodes and clients, and which are currently active. The registration /membership system is also well done. Dubbed the “BA Libre Location System” or BALLS for short, the project’s web map lists 259 “points of interest”, that is, either nodes or users who have decided to take part in this project in the whole capital city and its metro area of influence, with 13 on-line nodes and APs in BA city at the time of this writing. There is also a Wiki, an IRC channel and mailing lists.”

“Slow scan television is a way of sending video over a voice bandwidth channel–this can make it practical to send video over thousands of miles via ionospheric propagation. Modern computers have this once rare and expensive mode readily available to the average ham.”
