翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Freifunk ： ウィキペディア英語版 Freifunk Freifunk (German for: "free radio") is a non-commercial open grassroots initiative to support free radio networks in the German region. Freifunk is part of the international movement for open wireless radio networks. For more information on such projects around the world, see wireless community network. The initiative counts about 150 local communities with nearly 20,000 access points.〔http://www.freifunk-karte.de/〕 Among them, Hamburg, Munich, Paderborn and Düsseldorf are the biggest communities, with Hamburg connecting more than 720 access points.〔http://freifunk.net/wie-mache-ich-mit/community-finden/ Freifunk.net Overview Map〕 The main goals of Freifunk are to build a network that is decentralized, owned by those who run it and to support local communication. The initiative is based on the Picopeering Agreement.〔http://www.picopeer.net/PPA-en.html〕 In this agreement, participants agree upon a network that is free from discrimination, in the sense of net neutrality. == Technology == Like many other free community-driven networks, Freifunk uses mesh technology to bring up ad hoc WLAN networks. In a mesh network, all routers connect to each other using a special software. When a router fails, this software automatically calculates a new route to the destination. In this case, the software is called Freifunk firmware and it is based on OpenWrt and other free software. There are several different implementations of the firmware depending on the hardware and protocols local communities use. The two common protocols are OLSR and B.A.T.M.A.N.〔http://freifunk.net/worum-geht-es/technik-der-community-netzwerke/〕〔Wireless Networking in the Developing World. A practical guide to planning and building low-cost telecommunications infrastructure, Chapter 8: "Mesh Networking", pp. 134〕 The development of B.A.T.M.A.N. is driven by Freifunk activists. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Freifunk」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
