Guifi.net
Guifi.net is a free, open and neutral, mostly wireless community network, with over 37,000 active nodes and about 71,000 km of wireless links (as of December 2021). The majority of these nodes are located in Catalonia and the Valencian Community, in Spain, but the network is growing in other parts of the world. The network is self-organized and operated by the users using unlicensed wireless links and open optical fiber links. The nodes of the Telecommunications network, network are contributed by individuals, companies and administrations that freely connect to an open telecommunications network and extend the network wherever the infrastructure and content might not otherwise be accessible. Nodes join the network following the self-provision model since the whole structure is explicitly open to facilitate understanding how it is structured, so that everyone can create new sections as required. That results in a network infrastructure commons that provides abundant connectivi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wireless Community Network
Wireless community networks or wireless community projects or simply community networks, are non-centralized, self-managed and collaborative networks organized in a grassroots fashion by communities, non-governmental organizations 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, 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 policy, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NYC Mesh
NYC Mesh is a physical network of interconnected routers and a group of enthusiasts working to support the expansion of the project as a freely accessible, open, wireless community network. NYC Mesh is not an Internet service provider (ISP), although it does connect to the internet and offer internet access as a service to members. The network includes over 2,000 active member nodes throughout the five boroughs of New York City, with concentrations of users in Manhattan and Brooklyn. Aim The goal of NYC Mesh is to build a large scale, decentralized digital network, owned by those who run and use it, that will eventually cover all of New York City and neighboring urban areas. Participation in the project is governed by its Network Commons License. This agreement, partially modeled on a similar license in use by Guifi.net, lists four key tenets: * Participants are free to use the network for any purpose that does not limit the freedom of others to do the same, * Participants are ...

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 net ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wireless Commons License
The Wireless Commons License describes the principles, terms and conditions for many libre and open wireless community networks. In summary it gives the right to use the network for any purpose unless you affect the operation of the network or the freedom of other users, the right to know and learn any detail of the network and its components, the freedom of joining or extending the network following the same conditions. Community networks following this license are used, owned, operated, extended and governed by the community, the same group people with no separation between service providers and users. It can be seen as an equivalent license for libre and open wireless community networks compared to software licenses for libre and open software.

Tarragona
Tarragona (, ; ) is a coastal city and municipality in Catalonia (Spain). It is the capital and largest town of Tarragonès county, the Camp de Tarragona region and the province of Tarragona. Geographically, it is located on the Costa Daurada area on the Mediterranean Sea, Mediterranean shore. During the period of the Roman Empire, it was one of the most prominent cities of the Iberian Peninsula, as the capital, successively, of the Roman provinces of Hispania Citerior and Hispania Tarraconensis. The Archaeological Ensemble of Tárraco, Archaeological Complex of Tàrraco is a UNESCO World Heritage Site. History Punic Etymology Ta-Aragona name in Phoenician means the Aragona, which is the native Iberian term for the Ebro Vallay. Mythical Origins One Catalan legend holds that Tarragona was named for ''Tarraho'', eldest son of Tubal in c. 2407 BC; another (derived from Strabo and Megasthenes) attributes the name to 'Taharqa, Tearcon the Ethiopian', a seventh-century BC pharaoh w ...

Internet Service Provider
An Internet service provider (ISP) is an organization that provides a myriad of services related to accessing, using, managing, or participating in the Internet. ISPs can be organized in various forms, such as commercial, community-owned, non-profit, or otherwise privately owned. Internet services typically provided by ISPs can include internet access, internet transit, domain name registration, web hosting, and colocation. History The Internet (originally ARPAnet) was developed as a network between government research laboratories and participating departments of universities. Other companies and organizations joined by direct connection to the backbone, or by arrangements through other connected companies, sometimes using dialup tools such as UUCP. By the late 1980s, a process was set in place towards public, commercial use of the Internet. Some restrictions were removed by 1991, shortly after the introduction of the World Wide Web. During the 1980s, online s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Service Providers Of Spain
The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the interlinked hypertext documents and applications of the World Wide Web (WWW), electronic mail, internet telephony, streaming media and file sharing. The origins of the Internet date back to research that enabled the time-sharing of computer resources, the development of packet switching in the 1960s and the design of computer networks for data communication. The set of rules (communication protocols) to enable internetworking on the Internet arose from research and development commissioned in the 197 ...

Community Networks
A community network is a computer-based system that is intended to help support (usually geographical) communities by supporting, augmenting, and extending already existing social networks, by using networking technologies by, and for, a community. Free-nets and civic networks indicate roughly the same range of online projects and services, usually focused on bulletin board systems and online information, but sometimes also providing a means of network access directly to the Internet or other networks; whereas community technology centers (CTCs) and telecentres generally indicate a physical facility to compensate for lack of access to information and communication technologies (ICTs). Function Community networks often provide web space, e-mail, and other services for free, without advertising. VillageSoup launched a distinct form of community networking in 1997. This form uses display ads and informational postings from fee-paying business and organization members to generate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internetworking
Internetworking is the practice of interconnecting multiple computer networks. Typically, this enables any pair of hosts in the connected networks to exchange messages irrespective of their hardware-level networking technology. The resulting system of interconnected networks is called an ''internetwork'', or simply an ''internet''. The most notable example of internetworking is the Internet, a network of networks based on many underlying hardware technologies. The Internet is defined by a unified global addressing system, packet format, and routing methods provided by the Internet Protocol. The term ''internetworking'' is a combination of the components ''inter'' (between) and ''networking''. An earlier term for an internetwork is catenet, a short-form of ''(con)catenating networks''. History The first international heterogenous resource sharing network was developed by the computer science department at University College London (UCL) who interconnected the ARPANET with earl ...

Mesh Networking
A mesh network is a local area network network topology, topology in which the infrastructure Node (networking), nodes (i.e. bridges, switches, and other infrastructure devices) connect directly, dynamically and non-hierarchically to as many other nodes as possible and cooperate with one another to efficiently route data to and from clients. This lack of dependency on one node allows for every node to participate in the relay of information. Mesh networks dynamically self-organize and self-configure, which can reduce installation overhead. The ability to self-configure enables dynamic distribution of workloads, particularly in the event a few nodes should fail. This in turn contributes to fault-tolerance and reduced maintenance costs. Mesh topology may be contrasted with conventional Star network, star/Fat tree, tree local network topologies in which the bridges/switches are directly linked to only a small subset of other bridges/switches, and the links between these infrastruct ...
