Freifunk
Freifunk (German for: "free radio") is a non-commercial open grassroots initiative to support free computer networks in the German region. Freifunk is part of the international movement for a wireless community network. The initiative counts about 400 local communities with over 41,000 access points. Among them, Münster, Aachen, Munich, Hanover, Stuttgart, and Uelzen are the biggest communities, with more than 1,000 access points each. Aim The main goals of Freifunk are to build a large-scale free wireless Wi-Fi network that is decentralized, owned by those who run it and to support local communication. The initiative is based on the Picopeering Agreement. In this agreement, participants agree upon a network that is free from discrimination, in the sense of net neutrality. Similar grassroots initiatives in Austria and in Switzerland are FunkFeuer and Openwireless. Technology Like many other free community-driven networks, Freifunk uses mesh technology to bring up ad hoc ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wireless Community Network
Wireless community networks (WCNs) or wireless community projects or simply community networks, are non-centralized, self-managed and collaborative networks organized in a grassroots fashion by communities, NGO's and cooperatives in order to provide a viable alternative to municipal wireless networks for consumers. Many of these organizations set up wireless mesh networks which rely primarily on sharing of unmetered residential and business DSL and cable Internet. This sort of usage might be non-compliant with the terms of service of local internet service provider (ISPs) that deliver their service via the consumer phone and cable duopoly. Wireless community networks sometimes advocate complete freedom from censorship, and this position may be at odds with the acceptable use policies of some commercial services used. Some ISPs do allow sharing or reselling of bandwidth. The First Latin American Summit of Community Networks, held in Argentina in 2018, presented the following def ...

OpenWrt
OpenWrt (from ''open wireless router'') is an open-source project for embedded operating systems based on Linux, primarily used on embedded devices to route network traffic. The main components are Linux, util-linux, musl, and BusyBox. All components have been optimized to be small enough to fit into the limited storage and memory available in home routers. OpenWrt is configured using a command-line interface (ash shell) or a web interface (LuCI). There are about 8000 optional software packages available for installation via the opkg package management system. OpenWrt can run on various types of devices, including CPE routers, residential gateways, smartphones, pocket computers (e.g. Ben NanoNote). It is also possible to run OpenWrt on personal computers and laptops. History The OpenWrt project was started in 2004 after Linksys had built the firmware for their WRT54G series of wireless routers with code licensed under the GNU General Public License. Under the terms of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wireless Mesh Network
A wireless mesh network (WMN) is a communications network made up of radio nodes organized in a mesh topology. It can also be a form of wireless ad hoc network.Chai Keong Toh Ad Hoc Mobile Wireless Networks, Prentice Hall Publishers, 2002. A mesh refers to rich interconnection among devices or nodes. Wireless mesh networks often consist of mesh clients, mesh routers and gateways. Mobility of nodes is less frequent. If nodes constantly or frequently move, the mesh spends more time updating routes than delivering data. In a wireless mesh network, topology tends to be more static, so that routes computation can converge and delivery of data to their destinations can occur. Hence, this is a low-mobility centralized form of wireless ad hoc network. Also, because it sometimes relies on static nodes to act as gateways, it is not a truly all-wireless ad hoc network. Mesh clients are often laptops, cell phones, and other wireless devices. Mesh routers forward traffic to and from the gat ...

C-base
c-base e.V. is a non-profit association located in Berlin, Germany. Its purpose is to increase knowledge and skills pertaining to computer software, hardware and data networks. The association is engaged in numerous related activities. For example, the society has had stands at large festivals, such as Children's Day, where they introduce young people to topics like robotics and computer-aided design. The association's headquarters, c-base station, is also used by other initiatives and groups in and around Berlin as an event location or as function rooms, for example the wireless community network freifunk.net, the Chaos Computer Club and the Berlin Wikipedia group. Any group that identifies themselves with the purpose of the c-base are also welcome to use the premises for meetings and events. History Seventeen people founded c-base e. V. in the autumn of 1995. In the years 2002 and 2003 the BerlinBackBone project was launched to make available and promote free public access ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wireless Access Point
In computer networking, a wireless access point (WAP), or more generally just access point (AP), is a networking hardware device that allows other Wi-Fi devices to connect to a wired network. As a standalone device, the AP may have a wired connection to a router, but, in a wireless router, it can also be an integral component of the router itself. An AP is differentiated from a hotspot which is a physical location where Wi-Fi access is available. Connections An AP connects directly to a wired local area network, typically Ethernet, and the AP then provides wireless connections using wireless LAN technology, typically Wi-Fi, for other devices to use that wired connection. APs support the connection of multiple wireless devices through their one wired connection. Wireless data standards There are many wireless data standards that have been introduced for wireless access point and wireless router technology. New standards have been created to accommodate the increasing n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secondary Liability
Secondary liability, or indirect infringement, arises when a party materially contributes to, facilitates, induces, or is otherwise responsible for directly infringing acts carried out by another party. The US has statutorily codified secondary liability rules for trademarks and patents, but for matters relating to copyright, this has solely been a product of case law developments. In other words, courts, rather than Congress, have been the primary developers of theories and policies concerning secondary liability. Early case law Secondary liability in copyright has come about with case-by-case decisions. In other words, there has not been any real or consolidated theory. Furthermore, patent and copyright cases have tended to cross-cite each other. Examples of this are cases such as ''Kalem Co. v. Harper Brothers''''Kalem Co. v. Harper Brothers''222 U.S. 55(1911). (the producer of the movie Ben Hur (1907 film) didn't himself infringe, but was responsible for making and commercially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
