"Facilitated by a grant from the Tides Foundation, the new open80211s
(o11s) technology will enable the development and rollout of large-
scale mesh Wi-Fi networks for roughly half the cost of a traditional
network, says Geeks Without Frontiers. Designed to use existing
hardware to minimize cost and maximize availability, it's expected to
be particularly important in areas where legacy broadband models are
currently considered to be nonviable economically."
