A wireless network is a computer network that uses wireless data connections between network nodes.
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.
The Association for Progressive Communications (APC) is an international network of organizations that was founded in 1990 to provide communication infrastructure, including Internet-based applications, to groups and individuals who work for peace, human rights, protection of the environment, and sustainability. Pioneering the use of ICTs for civil society, especially in developing countries, APC were often the first providers of Internet in their member countries.
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.
A mesh network is a local network topology in which the infrastructure nodes 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.
The National Institute of Oceanography, founded on 1 January 1966 as one of 37 constituent laboratories of the CSIR, is an autonomous research organization in India to undertake scientific research and studies of special oceanographic features of the Northern Indian Ocean. Headquartered in Goa, it has regional centres in Kochi, Mumbai and Vizag.
eCorridors is an information technology program to promote and facilitate broadband access for communities of Virginia and nearby areas. It was developed by faculty at the Virginia Polytechnic Institute and State University (VT) in the spring of 2000.
In telecommunications, white spaces refer to radio frequencies allocated to a broadcasting service but not used locally. National and international bodies assign frequencies for specific uses and, in most cases, license the rights to broadcast over these frequencies. This frequency allocation process creates a bandplan which for technical reasons assigns white space between used radio bands or channels to avoid interference. In this case, while the frequencies are unused, they have been specifically assigned for a purpose, such as a guard band. Most commonly however, these white spaces exist naturally between used channels, since assigning nearby transmissions to immediately adjacent channels will cause destructive interference to both.
The CSIR-National Environmental Engineering Research Institute (CSIR-NEERI) is a research institute created and funded by Government of India. It was established in Nagpur in 1958 with focus on water supply, sewage disposal, communicable diseases and to some extent on industrial pollution and occupational diseases found common in post-independent India. NEERI is a pioneer laboratory in the field of environmental science and engineering and part of Council of Scientific and Industrial Research (CSIR). NEERI has five zonal laboratories at Chennai, Delhi, Hyderabad, Kolkata and Mumbai. NEERI falls under the Ministry of Science and Technology (India) of the central government. The NEERI is an important partner organisation in India's POPs national implementation plan (NIP).
Village Telco is an initiative to build low-cost community telephone network hardware and software. It is based on a suite of open-source applications that enable entrepreneurs to set up and operate a telephone service in a specific area or supporting the needs of a specific community.
Pretoria Wireless Users Group is a South African wireless users group. It is non-profit community organisation providing a wireless community network in Pretoria, the capital of South Africa.
South African wireless community networks are wireless networks that allow members to talk, send messages, share files and play games independent of the commercial landline and mobile telephone networks. Most of them use WiFi technology and many are wireless mesh networks. A wireless community network may connect to the public switched telephone network and/or the Internet, but there are various restrictions on connectivity in South Africa. Wireless community networks are particularly useful in areas where commercial telecommunications services are unavailable or unaffordable.
The Council for Scientific and Industrial Research (CSIR) is South Africa's central and premier scientific research and development organisation. It was established by an act of parliament in 1945 and is situated on its own campus in the city of Pretoria. It is the largest research and development (R&D) organisation in Africa and accounts for about 10% of the entire African R&D budget. It has a staff of approximately 3,000 technical and scientific researchers, often working in multi-disciplinary teams.
The Council for Scientific and Industrial Research (CSIR) was established by NLC Decree 293 of October 10, 1968 amended by NLCD 329 of 1969, and re-established in its present form by CSIR Act 521 on November 26, 1996. The genesis of the council however, dates back to the erstwhile National Research Council (NRC), which was established by the government in August 1958 to organize and coordinate scientific research in Ghana. In 1963, the NRC merged with the former Ghana Academy of Sciences, a statutory learned society. Following a review in 1966, the academy was reconstituted into, essentially, its original component bodies, namely a national research organization redesignated the CSIR and a learned Society, designated the Ghana Academy of Arts and Sciences.
Sascha Meinrath holds the Palmer Chair in Telecommunications at Penn State University. He is the founder of X-Lab, a future-focused technology policy and innovation think tank, and promotes the "Internet in a Suitcase" effort to create ad hoc mesh wireless technologies. Meinrath founded the Open Technology Institute in 2008 and directed the Institute while also serving as Vice President of the New America Foundation. He is also the co-founder and executive director of the CUWiN Foundation, a non-profit launched in 2000 that aims to develop "decentralized, community-owned networks that foster democratic cultures and local content," and in 2007 founded the Open Source Wireless Coalition, "a global partnership of open source wireless integrators, researchers, implementors and companies dedicated to the development of open source, interoperable, low-cost wireless network technologies." In 2012 he was elected as an Ashoka Global Fellow for leading support for Internet freedom in the United States and around the globe, as well as named to Newsweek's Digital Power Index Top 100 influencers among other “public servants defining digital regulatory boundaries” for his efforts to develop open-source, low-cost community wireless networks and his role in fighting Stop Online Piracy Act (SOPA) and the Protect IP Act (PIPA). In 2013 Time named Meinrath to the TIME Tech 40: The Most Influential Minds in Tech for his work to protect Internet freedom.
The advanced fire information system (AFIS) provides information on current and historical fires detected by sensors on Earth observation satellites, e.g. NASA MODIS, EUMETSAT MSG, GOES, NPP, etc. covering multiple regions across the globe. The system provides monitoring of active fire on a web-based map and delivers near real-time alerts to registered users when a fire is detected within their specified areas of interest via email, SMS, XMPP, etc.
