Wireless broadband is a telecommunications technology that provides high-speed wireless Internet access or computer networking access over a wide area. The term encompasses both fixed and mobile broadband.
A wireless network is a computer network that uses wireless data connections between network nodes. Wireless networking allows homes, telecommunications networks, and business installations to avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Admin telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure.
Multichannel multipoint distribution service (MMDS), formerly known as broadband radio service (BRS) and also known as wireless cable, is a wireless telecommunications technology, used for general-purpose broadband networking or, more commonly, as an alternative method of cable television programming reception.
Wireless local loop (WLL) is the use of a wireless communications link as the "last mile / first mile" connection for delivering plain old telephone service (POTS) or Internet access to telecommunications customers. Various types of WLL systems and technologies exist.
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.
Worldwide Interoperability for Microwave Access (WiMAX) is a family of wireless broadband communication standards based on the IEEE 802.16 set of standards, which provide physical layer (PHY) and media access control (MAC) options.
The S band is a designation by the Institute of Electrical and Electronics Engineers (IEEE) for a part of the microwave band of the electromagnetic spectrum covering frequencies from 2 to 4 gigahertz (GHz). Thus it crosses the conventional boundary between the UHF and SHF bands at 3.0 GHz. The S band is used by airport surveillance radar for air traffic control, weather radar, surface ship radar, and some communications satellites, particularly satellites used by NASA to communicate with the Space Shuttle and the International Space Station. The 10 cm radar short-band ranges roughly from 1.55 to 5.2 GHz. India's regional satellite navigation network (IRNSS) broadcasts on 2.483778 to 2.500278 GHz.
The V band ("vee-band") is a standard designation by the Institute of Electrical and Electronics Engineers (IEEE) for a band of frequencies in the microwave portion of the electromagnetic spectrum ranging from 40 to 75 gigahertz (GHz). The V band is not heavily used, except for millimeter wave radar research and other kinds of scientific research. It should not be confused with the 600–1,000 MHz range of Band V of the UHF frequency range.
Satellite Internet access is Internet access provided through communication satellites; if it can sustain high speeds, it is termed satellite broadband. Modern consumer grade satellite Internet service is typically provided to individual users through geostationary satellites that can offer relatively high data speeds, with newer satellites using the Ku band to achieve downstream data speeds up to 506 Mbit/s. In addition, new satellite internet constellations are being developed in low-earth orbit to enable low-latency internet access from space.
Microwave transmission is the transmission of information by electromagnetic waves with wavelengths in the microwave frequency range of 300 MHz to 300 GHz of the electromagnetic spectrum. Microwave signals are normally limited to the line of sight, so long-distance transmission using these signals requires a series of repeaters forming a microwave relay network. It is possible to use microwave signals in over-the-horizon communications using tropospheric scatter, but such systems are expensive and generally used only in specialist roles.
Unwired Australia Pty Ltd was an Australian company dedicated to fixed wireless telecommunications network offering carrier grade Internet services. They provided coverage in Melbourne and Sydney. As of 8 March 2010 Unwired had 52,320 customers and 97 employees. The technology used by Unwired was provided by American manufacturer Navini Networks and Venturi Wireless Solutions.
Skyriver was a business broadband Internet provider headquartered in San Diego, California. It was acquired by One Ring Networks in July, 2018. Skyriver delivered broadband Internet connectivity for enterprise and small-medium businesses, utilizing its proprietary millimeter wave technology. Skyriver offered commercial grade services including dedicated Internet access, Virtual Private Network (VPN), redundancy, and temporary Internet/event bandwidth in California.
Fixed wireless is the operation of wireless communication devices or systems used to connect two fixed locations with a radio or other wireless link, such as laser bridge. Usually, fixed wireless is part of a wireless LAN infrastructure. The purpose of a fixed wireless link is to enable data communications between the two sites or buildings. Fixed wireless data (FWD) links are often a cost-effective alternative to leasing fiber or installing cables between the buildings.
SSi Canada is a Canadian wireless broadband internet service provider primarily serving remote areas that lack terrestrial service options. SSi was established in 1990 by Jeffrey Philipp and is headquartered in Yellowknife, capital of the Northwest Territories. SSi is also a provider of Satellite Communication services, offered in locations that do not have terrestrial service options. They offer turnkey Internet systems to other ISPs. They have a local market serving all 25 communities in Nunavut and several in the Northwest Territories. These two territories account for 1/3 of Canada's landmass covering 3,439,296 km2 (1,327,920 sq mi). They also have an international market including Africa, Indonesia and Kiribati.
Gigabit wireless is the name given to wireless communication systems whose data transfer speeds reach or exceed one gigabit per second. Such speeds are achieved with complex modulations of the signal, such as quadrature amplitude modulation (QAM) or signals spanning many frequencies. When a signal spans many frequencies, physicists refer that a wide bandwidth signal. In the communication industry, many wireless internet service providers and cell phone companies deploy wireless radio frequency antennas to backhaul core networks, connect businesses, and even individual residential homes.
Navini Networks was a company that developed an Internet access system based on WiMAX wireless communication standards. This access system was subsequently acquired by Cisco Systems in October, 2007.
Towerstream Corporation is a Fixed Wireless Fiber Alternative company delivering high-speed Internet access to businesses. The company offers broadband services in 12 urban markets including New York City, Boston, Los Angeles, Chicago, Philadelphia, the San Francisco Bay area, Miami, Seattle, Dallas-Fort Worth, Houston, Las Vegas-Reno, and the greater Providence area, where the company is headquartered. In 2014, Towerstream launched its On-Net fixed-wireless service offering On-Net building tenants access to dedicated, symmetrical high-speed Internet connectivity, with a premier SLA, at market-setting prices. Founded in 1999 by Philip Urso and Jeffrey Thompson (eFortress), Towerstream held its first public offering in January 2007 and traded on the NASDAQ Capital Markets under symbol TWER. In November 2016 the stock had declined in price, was delisted from NASDAQ, and moved to the over-the-counter market.
Aereo was a technology company based in New York City that allowed subscribers to view live and time-shifted streams of over-the-air television on Internet-connected devices. The service opened to customers in March 2012, and was backed by Barry Diller's IAC.
