A wireless network is a computer network that uses wireless data connections between network nodes.
Wireless community networks (WCNs) or wireless community projects are organizations that take a grassroots approach to providing a viable alternative to municipal wireless networks for consumers.
Linksys is an American brand of data networking hardware products mainly sold to home users and small businesses. It was founded in 1988 by the couple Victor and Janie Tsao, both Taiwanese immigrants to the United States. Linksys products include WiFi routers, mesh WiFi systems, Wifi extenders, access points, network switches, WiFi networking and smart home automation products. It is headquartered in Irvine, California.
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.
The University of California Davis School of Medicine is one of six University of California medical schools in the state of California, and is associated with University of California, Davis.
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 from/to 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.
UC Davis Medical Center is part of UC Davis Health and a major academic health center located in Sacramento, California. It is owned and operated by the University of California as part of its University of California, Davis campus. The medical center sits on a 142-acre (57 ha) campus located between the Elmhurst, Tahoe Park, and Oak Park residential neighborhoods. The site incorporates the land and some of the buildings of the former Sacramento Medical Center as well as much of the land previously occupied by the California State Fair until its 1967 move to a new location.
Z-Wave is a wireless communications protocol used primarily for home automation. It is a mesh network using low-energy radio waves to communicate from appliance to appliance, allowing for wireless control of residential appliances and other devices, such as lighting control, security systems, thermostats, windows, locks, swimming pools, and garage door openers. Like other protocols and systems aimed at the home and office automation market, a Z-Wave system can be controlled via the Internet from a smart phone, tablet, or computer, and locally through a smart speaker, wireless keyfob, or wall-mounted panel with a Z-Wave gateway or central control device serving as both the hub controller and portal to the outside. Z-Wave provides the application layer interoperability between home control systems of different manufacturers that are a part of its alliance. There are a growing number of interoperable Z-Wave products; over 1,700 in 2017, and over 2,600 by 2019.
Network coding is a field of research founded in a series of papers from the late 1990s to the early 2000s. However, the concept of network coding, in particular linear network coding, appeared much earlier. In a 1978 paper, a scheme for improving the throughput of a two-way communication through a satellite was proposed. In this scheme, two users trying to communicate with each other transmit their data streams to a satellite, which combines the two streams by summing them modulo 2 and then broadcasts the combined stream. Each of the two users, upon receiving the broadcast stream, can decode the other stream by using the information of their own stream.
Wireless Nomad (wirelessnomad.com) was a for-profit cooperative based in Toronto, Canada providing subscriber-owned home and business Internet access along with free Wi-Fi wireless Internet access and music to over a hundred nodes, making it the largest free Wi-Fi network in the country at the time. It was founded by Steve Wilton and Damien Fox in January 2005, and turned its DSL internet connections over to private ISP TekSavvy in March 2009. All WiFi nodes were subsequently shut down.
Municipal broadband is broadband Internet access owned by public entities. Services are often provided either fully or partially by local governments to residents within certain areas or jurisdictions. Common connection technologies include unlicensed wireless, licensed wireless, and fiber optic cable. Many cities that previously deployed Wi-Fi based solutions, like Comcast and Charter Spectrum, are switching to municipal broadband. Municipal fiber-to-the-home networks are becoming more prominent because of increased demand for modern audio and video applications, which are increasing bandwidth requirements by 40% per year. Supporters of municipal broadband argue that when cities create their own internet and broadband, customers ultimately get faster internet speeds, lower prices, and better customer service than from internet service providers. The purpose of municipal broadband is to provide internet access to those who cannot afford internet from internet service providers and local governments are increasingly investing in said services for their communities.
In a hierarchical telecommunications network, the backhaul portion of the network comprises the intermediate links between the core network, or backbone network, and the small subnetworks at the edge of the network.
The High Performance Wireless Research and Education Network (HPWREN) is a network research program, funded by the National Science Foundation. The program includes the creation, demonstration, and evaluation of a non-commercial, prototype, high-performance, wide-area, wireless network in its Southern California service area.
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.
Firetide is an American, international provider of wireless mesh network technology. Based in the Silicon Valley, Firetide designs and sells hardware and software for wireless networks. Firetide's products have been used in over 2000 installations in 40 countries.
Quail Ridge Reserve is a 2,000-acre (810 ha) nature reserve in northern California. It is located in the vicinity of Lake Berryessa and the Blue Ridge Berryessa Natural Area, in Napa County, California.
IEEE 802.11s is a wireless LAN standard and an IEEE 802.11 amendment for mesh networking, defining how wireless devices can interconnect to create a wireless LAN (WLAN) mesh network, which may be used for relatively fixed topologies and wireless ad hoc networks. The IEEE 802.11s task group drew upon volunteers from university and industry to provide specifications and possible design solutions for wireless mesh networking. As a standard, the document was iterated and revised many times prior to finalization.
The UCLA Smart Grid Energy Research Center (SMERC), located on the University of California Los Angeles (UCLA) campus, is an organization focused on developing the next generation of technologies and innovation for the SmartGrid.
