The DC Community Access Network (District of Columbia Community Access Network) (DC-CAN) is a 100 gigabit middle mile network [1] funded by the city of Washington, D.C. which will make broadband internet access available to over 250 health, educational, public safety, and other community anchor institutions. [2] [3] The network mainly focuses on underserved areas of the district. [4]
The project was estimated to cost $25 million [5] and was partially funded by the American Recovery and Reinvestment Act of 2009, providing $17 million of federal grants, [6] [7] with the goal to provide affordable broadband Internet service to more than 250 community anchor institutions. [8] The funding required the project to be completed by June 30, 2013 [9]
Construction broke ground in April 2011, [10] and the network's first link was activated on 7 December 2011 connecting 24 institutions to the network. [11] As of 2012, the city had laid more than 67 miles of fiber-optic cables. [12]
The network has been criticised for relying on private companies to provide internet services to customers, as the network only provides the physical cabling for the internet, not the services themselves. [13]

Internet access is a facility or service that provides connectivity for a computer, a computer network, or other network device to the Internet, and for individuals or organizations to access or use applications such as email and the World Wide Web. Internet access is offered for sale by an international hierarchy of Internet service providers (ISPs) using various networking technologies. At the retail level, many organizations, including municipal entities, also provide cost-free access to the general public.
A wireless Internet service provider (WISP) is an Internet service provider with a network based on wireless networking. Technology may include commonplace Wi-Fi wireless mesh networking, or proprietary equipment designed to operate over open 900 MHz, 2.4 GHz, 4.9, 5, 24, and 60 GHz bands or licensed frequencies in the UHF band, LMDS, and other bands from 6 GHz to 80 GHz.
Broadband over power lines (BPL) is a method of power-line communication (PLC) that allows relatively high-speed digital data transmission over public electric power distribution wiring. BPL uses higher frequencies, a wider frequency range, and different technologies compared to other forms of power-line communications to provide high-rate communication over longer distances. BPL uses frequencies that are part of the radio spectrum allocated to over-the-air communication services; therefore, the prevention of interference to, and from, these services is a very important factor in designing BPL systems.
A telecentre is a public place where people can access computers, the Internet, and other digital technologies that enable them to gather information, create, learn, and communicate with others while they develop essential digital skills. Telecentres exist in almost every country, although they sometimes go by a different names including public internet access center (PIAP), village knowledge center, infocenter, Telecottage, Electronic Village Hall, community technology center (CTC), community multimedia center (CMC), multipurpose community telecentre (MCT), Common/Citizen Service Centre (CSC) and school-based telecentre. While each telecentre is different, their common focus is on the use of digital technologies to support community, economic, educational, and social development—reducing isolation, bridging the digital divide, promoting health issues, creating economic opportunities, and reaching out to youth for example.
The Corporation for Education Network Initiatives in California is a nonprofit corporation formed in 1997 to provide high-performance, high-bandwidth networking services to California universities and research institutions. Through this corporation, representatives from all of California's K-20 public education combine their networking resources toward the operation, deployment, and maintenance of the California Research and Education Network, or CalREN. Today, CalREN operates over 8,000 miles of fiber optic cable and serves more than 20 million users.
Fiber to the x or fiber in the loop is a generic term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications. As fiber optic cables are able to carry much more data than copper cables, especially over long distances, copper telephone networks built in the 20th century are being replaced by fiber.
Municipal broadband, sometimes referred to as a "Government-owned Network" or GON, is broadband Internet access offered 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. 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 Internet in the United States grew out of the ARPANET, a network sponsored by the Advanced Research Projects Agency of the U.S. Department of Defense during the 1960s. The Internet in the United States in turn provided the foundation for the worldwide Internet of today.
The United Kingdom has been involved with the Internet throughout its origins and development. The telecommunications infrastructure in the United Kingdom provides Internet access to businesses and home users in various forms, including fibre, cable, DSL, wireless and mobile.
Internet in India began in 1986 and was initially available only to the educational and research community. General public access to the internet in India began on 15 August 1995. American multinational digital communications technology conglomerate Cisco estimated that India will have more than 900 million Internet users by 2023.
Merit Network, Inc., is a nonprofit member-governed organization providing high-performance computer networking and related services to educational, government, health care, and nonprofit organizations, primarily in Michigan. Created in 1966, Merit operates the longest running regional computer network in the United States.
Broadband is a term normally considered to be synonymous with a high-speed connection to the internet. Suitability for certain applications, or technically a certain quality of service, is often assumed. For instance, low round trip delay would normally be assumed to be well under 150ms and suitable for Voice over IP, online gaming, financial trading especially arbitrage, virtual private networks and other latency-sensitive applications. This would rule out satellite Internet as inherently high-latency. In some applications, utility-grade reliability or security are often also assumed or defined as requirements. There is no single definition of broadband and official plans may refer to any or none of these criteria.
ACD is a Competitive Local Exchange Carrier and Internet Service Provider, headquartered in Lansing, Michigan. ACD provides Fiber Optic Service, Metro Ethernet, Telephone, Hosted Phone Service, DSL, Datacenter and Web hosting services to all types of customers.
10G-PON is a 2010 computer networking standard for data links, capable of delivering shared Internet access rates up to 10 Gbit/s over existing dark fiber. This is the ITU-T's next generation standard following on from GPON or Gigabit-capable PON. Optical fibre is shared by many subscribers in a network known as FTTx in a way that centralises most of the telecommunications equipment, often displacing copper phone lines that connect premises to the phone exchange. Passive optical network (PON) architecture has become a cost-effective way to meet performance demands in access networks, and sometimes also in large optical local networks for "Fibre-to-the-desk".
Broadband universal service, also known as "universal service obligation" (USO) or "universal broadband service", refers to government efforts to ensure all citizens have access to the internet. Universal voice service obligations have been expanded to include broadband service obligations in Switzerland, Finland, Spain and the UK.
Gigabit Seattle was a fiber-to-the-home / fiber-to-the-business network planned to be deployed in Seattle, Washington. The network comes out of a partnership between the City of Seattle, the University of Washington and digital economic development company Gigabit Squared to deploy a next generation network in the City. The project is the second city project announced by Gigabit Squared as part of its Gigabit Neighborhood Gateway Program, after Gigabit Chicago.
Gigabit Squared, LLC was a digital economic development corporation that specialized in the planning, implementation and rollout of communications infrastructure. Unlike incumbent telecommunications providers in the United States, who typically own and operate networks in addition to providing wholesale and retail Internet access services, Gigabit Squared designed and built networks, but does not always finance, operate and maintain those networks.
CityFibre is an independent British network provider, providing gigabit-capable FTTP broadband across the UK. It is the third-largest network provider in the UK, after Openreach and Virgin Media. It is sometimes referred to as an "altnet", in reference to being an alternative option to Openreach.
