The Jhai Foundation is demonstrating its ruggedized bicycle-powered WiFi access points in San Francisco tomorrow. These meshing wireless bridges are intended for use in rural Laos, as part of a sustainable economic development project.
When: Tuesday, December 2, at 10 a.m
Where: Jhai Foundation, 921 France Ave., San Francisco, CA 94112
The relay point would therefore have a computer (the "relay PC")serving the access point function for the villages and providing a link (the "backhaul" in the language of telephony) to the phone lines at Phon Hong. This computer would be a remote installation where access is by foot up a trail of moderate difficulty. It would be solar powered and highly resistant to environmental factors.
At Phon Hong the "server PC" would be installed on a water tower having an unblocked view of the mountain ridge. High-gain (24 dbi parabolic) antennas would be installed at the villages and at the server, while lower-gain "patch" antennas would be installed at the relay PC.
