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.
Digital Enhanced Cordless Telecommunications, usually known by the acronym DECT, is a standard used for creating cordless telephone systems and for IoT systems. It originated in Europe, where it is the common standard, replacing earlier cordless phone standards, such as 900 MHz CT1 and CT2. The IoT usage relies on the new DECT-2020 standard.
The primary regulator of telecommunications in Malaysia is the Malaysian Communications and Multimedia Commission (MCMC). It issues licenses under the Communications and Multimedia Act 1998, the Postal Services Act 2012 and the Digital Signature Act 1997.
In telephony, the local loop is the physical link or circuit that connects from the demarcation point of the customer premises to the edge of the common carrier or telecommunications service provider's network.
Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 megahertz (MHz) and 3 gigahertz (GHz), also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter. Radio waves with frequencies above the UHF band fall into the super-high frequency (SHF) or microwave frequency range. Lower frequency signals fall into the VHF or lower bands. UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, satellite phones, and numerous other applications.
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.
A cordless telephone or portable telephone has a portable telephone handset that connects by radio to a base station connected to the public telephone network. The operational range is limited, usually to the same building or within some short distance from the base station.
A landline is a telephone connection that uses metal wires from the owner's premises also referred to as: POTS, Twisted pair, telephone line or public switched telephone network (PSTN).
The Generic Access Profile (GAP) describes a set of mandatory requirements to allow any conforming DECT Fixed Part (base) to interoperate with any conforming DECT Portable Part (handset) to provide basic telephony services when attached to a 3.1 kHz telephone network.
GCI Communication Corp (GCI) is a telecommunications corporation operating in Alaska. Through its own facilities and agreements with other providers, GCI provides cable television service, Internet access, wireline (networking), and cellular telephone service. It is a subsidiary of Colorado-based company Liberty Broadband, a company affiliated with Liberty Media that also owns a 26% interest in Charter Communications, having been originally acquired by Liberty in 2015.
Wi-Fi calling refers to mobile phone voice calls and data that are made over IP networks using Wi-Fi, instead of the cell towers provided by cellular networks. Using this feature, compatible handsets are able to route regular cellular calls through a wireless LAN (Wi-Fi) network with broadband Internet, while seamlessly change connections between the two where necessary. This feature makes use of the Generic Access Network (GAN) protocol, also known as Unlicensed Mobile Access (UMA).
The telecommunications industry in China is dominated by three state-run businesses: China Telecom, China Unicom and China Mobile. The three companies were formed by restructuring launched in May 2008, directed by the Ministry of Information Industry (MII), National Development and Reform Commission (NDRC) and the Minister of Finance. Since then, all three companies gained nationwide fixed-line and cellular mobile telecom licenses in China. In 2019, all three telecoms were issued 5G national licenses.
Mobile VoIP or simply mVoIP is an extension of mobility to a voice over IP network. Two types of communication are generally supported: cordless telephones using DECT or PCS protocols for short range or campus communications where all base stations are linked into the same LAN, and wider area communications using 3G or 4G protocols.
Fritz!Box, stylised as FRITZ!Box, is a series of residential gateway devices produced by the German company AVM GmbH. In 2010 it was estimated the series had a market share of 68% of the digital subscriber line (DSL) consumer equipment in Germany.
Net3 was a Wi-Fi-like system developed, manufactured and commercialised by Olivetti in the early 1990s. It could wirelessly connect PCs to an Ethernet fixed LAN at a speed of up to 512kbit/s, over a very wide area. It was a micro-cellular system, in which each base station had an effective range of about 100m indoors, 300m outdoors, and the system supported seamless handover between base stations.
A headset is a combination of headphone and microphone. Headsets connect over a telephone or to a computer, allowing the user to speak and listen while keeping both hands free. They are commonly used in customer service and technical support centers, where employees can converse with customers while typing information into a computer. They are also common among computer gamers and let them talk with each other and hear others while using their keyboards and mice to play the game.
TIA/EIA-662 is a 1995 telecommunications standard from the Telecommunications Industry Association, a 1988 offshoot of the EIA. The standard addresses Personal Wireless Telecommunications (PWT).
DSP Group, Inc. was an American company that manufactured chipsets for VoIP, multimedia, and digital cordless applications. Founded in 1987 with headquarters in San Jose, California, DSP Group employed over 400 people at three US sites and offices in Germany, Scotland, Israel, India, Hong Kong and Japan until it was acquired by Synaptics.
