SFLan -- Community Wireless

What is Internet Archive Community Wireless?

How? Divide the problem properly among three players: City + Backbone Non Profit + last 100 feet

Status as of April 2008:


high resolution version

Version 2 of our community wireless project (SFlan) was built on custom linux boxes by Clif Cox and Ralf Muehlen in 2003. This was a rooftop network that peaked at 50 nodes in San Francisco. These were on top of individual's homes and most of the funding came from those individuals. This worked, but was not very reliable. The lesson learned from this is get high locations, with solid networks to them, and easy physical access. These features are now becoming available through cooperation with the City of San Francisco for version 3.

Version 1 of our community wireless project (SFlan) was started in 1997 using Aironet gear (before 802.11, WiFi, or their being acquired by Cisco) to make a wireless network around the Presidio of San Francisco. This network was modeled on Harvey Branscomb's wireless system in Aspen Colorado, funded by Sun Labs. We found the technology worked, more or less, but access to high locations that had good connectivity were needed. The governing entity of the National Park in the Presidio of San Francisco did not help in any way, and this was death nell. In fact they made us take down our antennas from a radio tower because of an exclusive deal they had made with a phone company.
