Technology
AWMN makes extensive use of the IEEE 802.11x (a/b/g/n) set of standards and operates on the 2.4GHz (mainly for the Open APs) and 5.4GHz (for the backbone links) license-free ISM frequency bands. Over the last few years, AWMN has tested (and later used in production environments) equipment from a huge variety of vendors.
The routing protocol used by the network is BGP. Efforts have been made to move towards new, more adaptive, experimental protocols such as OLSR and B.A.T.M.A.N.. Some members of the AWMN community have contributed feedback and code to many Linux routing projects.
Homemade equipment is encouraged. Many workshops have been held so that members can become familiar with constructing their own aerials and cables. Additionally, the community regularly organizes seminars to educate aspiring network administrators on wireless technologies, protocols, routing and Linux, in the conditions of an operational large-scale network.
A wide variety of software is used in the network but AWMN services rely heavily on Open-source software, GNU/Linux (or other free Unix variants).

Famous quotes containing the word technology:
“Primitive peoples tried to annul death by portraying the human body—we do it by finding substitutes for the human body. Technology instead of mysticism!”
—Max Frisch (1911–1991)
“The successor to politics will be propaganda. Propaganda, not in the sense of a message or ideology, but as the impact of the whole technology of the times.”
—Marshall McLuhan (1911–1980)
“The real accomplishment of modern science and technology consists in taking ordinary men, informing them narrowly and deeply and then, through appropriate organization, arranging to have their knowledge combined with that of other specialized but equally ordinary men. This dispenses with the need for genius. The resulting performance, though less inspiring, is far more predictable.”
—John Kenneth Galbraith (b. 1908)
