Telecommunications equipment (also telecoms equipment or communications equipment) is a hardware which is used for the purposes of telecommunications. Since the 1990s the boundary between telecoms equipment and IT hardware has become blurred as a result of the growth of the internet and its increasing role in the transfer of telecoms data.
Telecommunications equipment can be broadly broken down into the following categories:
Most of the essential elements of modern telecommunication are built from MOSFETs (metal-oxide-semiconductor field-effect transistors), including mobile devices, transceivers, base station modules, routers, RF power amplifiers,microprocessors, memory chips, and telecommunication circuits. As of 2005, telecommunications equipment account for 16.5% of the annual microprocessor market.
The world's largest telecommunications equipment vendors by revenues in 2017 are:
A wireless network is a computer network that uses wireless data connections between network nodes.
In telecommunications, a customer-premises equipment or customer-provided equipment (CPE) is any terminal and associated equipment located at a subscriber's premises and connected with a carrier's telecommunication circuit at the demarcation point ("demarc"). The demarc is a point established in a building or complex to separate customer equipment from the equipment located in either the distribution infrastructure or central office of the communications service provider.
Telephony is the field of technology involving the development, application, and deployment of telecommunication services for the purpose of electronic transmission of voice, fax, or data, between distant parties. The history of telephony is intimately linked to the invention and development of the telephone.
A telecommunications network is a group of nodes interconnected by links that are used to exchange messages between the nodes. The links may use a variety of technologies based on the methodologies of circuit switching, message switching, or packet switching, to pass messages and signals. For each message, multiple nodes may cooperate to pass the message from an originating node to the a destination node, via multiple network hops. For this routing function each node in the network is assigned a network address for identification and locating it on the network. The collection of addresses in the network is called the address space of the network.
Wireless communication is the electromagnetic transfer of information between two or more points that are not connected by an electrical conductor. The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mouse, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications include the use of other electromagnetic wireless technologies, such as light, magnetic, or electric fields or the use of sound.
The telecommunications industries within the sector of information and communication technology is made up of all telecommunications/telephone companies and internet service providers and plays the crucial role in the evolution of mobile communications and the information society.
A mixed-signal integrated circuit is any integrated circuit that has both analog circuits and digital circuits on a single semiconductor die. In real-life applications mixed-signal designs are everywhere, for example, smart mobile phones. Mixed-signal ICs also process both analog and digital signals together. For example, an analog-to-digital converter is a mixed-signal circuit. Mixed-signal circuits or systems are typically cost-effective solutions for building any modern consumer electronics applications.
MRV Communications is a communications equipment and services company based in Chatsworth, California. The company, through its business units, is a provider of optical communications network infrastructure equipment and services to a broad range of telecom concerns, including multinational telecommunications operators, local municipalities, MSOs, corporate and consumer high speed G-Internet service providers, and data storage and cloud computing providers. MRV Communications was acquired by ADVA Optical Networking on August 14, 2017.
The history of mobile phones covers mobile communication devices that connect wirelessly to the public switched telephone network.
Networking hardware, also known as network equipment or computer networking devices, are electronic devices which are required for communication and interaction between devices on a computer network. Specifically, they mediate data transmission in a computer network. Units which are the last receiver or generate data are called hosts, end systems or data terminal equipment.
The history of telecommunication began with the use of smoke signals and drums in Africa, Asia, and the Americas. In the 1790s, the first fixed semaphore systems emerged in Europe. However, it was not until the 1830s that electrical telecommunication systems started to appear. This article details the history of telecommunication and the individuals who helped make telecommunication systems what they are today. The history of telecommunication is an important part of the larger history of communication.
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.
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 Ministry of Information Industry (MII), Nationals Development and Reform Commissions (NDRC) and Minister of Finance. Since then, all the three companies gained 3G licenses and engaged fixed-line and mobile business in China.
Telecommunication Company of Iran, or TCI is the fixed-line incumbent operator in Iran offering services in fixed telephony, DSL and data services for both residential and business customers, all throughout the country. It was established in 1971 with a new organizational structure as the main responsible administration for the entire telecommunication affairs.
The following outline is provided as an overview of and topical guide to telecommunication:
Telecommunications Engineering is an engineering discipline centered on electrical and computer engineering which seeks to support and enhance telecommunication systems. The work ranges from basic circuit design to strategic mass developments. A telecommunication engineer is responsible for designing and overseeing the installation of telecommunications equipment and facilities, such as complex electronic switching systems, and other plain old telephone service facilities, optical fiber cabling, IP networks, and microwave transmission systems. Telecommunications engineering also overlaps with broadcast engineering.
The Centre for Development of Telematics (C-DOT) is an Indian Government owned telecommunications technology development centre. It was established in 1984 with initial mandate of designing and developing digital exchanges. C-DOT has expanded to develop intelligent computer software applications. It has offices in Delhi, Bangalore and Kolkata. It is one of the 2 Indian Government organisations which have been appraised at Maturity Level 5 of CMMI-DEV v1.3, other being Bharat Electronics Limited (BEL) Software Technology Centre.
Edholm's law, proposed by and named after Phil Edholm, refers to the observation that the three categories of telecommunication, namely wireless (mobile), nomadic and wired networks (fixed), are in lockstep and gradually converging. Edholm's law also holds that data rates for these telecommunications categories increase on similar exponential curves, with the slower rates trailing the faster ones by a predictable time lag. Edholm's law predicts that the bandwidth and data rates double every 18 months, which has proven to be true since the 1970s. The trend is evident in the cases of Internet, cellular (mobile), wireless LAN and wireless personal area networks.
Telecommunication is the exchange of signs, signals, messages, words, writings, images and sounds or information of any nature by wire, radio, optical or other electromagnetic systems. Telecommunication occurs when the exchange of information between communication participants includes the use of technology. It is transmitted through a transmission medium, such as over physical media, for example, over electrical cable, or via electromagnetic radiation through space such as radio or light. Such transmission paths are often divided into communication channels which afford the advantages of multiplexing. Since the Latin term communicatio is considered the social process of information exchange, the term telecommunications is often used in its plural form because it involves many different technologies.
The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET), also known as the metal–oxide–silicon transistor (MOS transistor, or MOS), is a type of insulated-gate field-effect transistor (IGFET) that is fabricated by the controlled oxidation of a semiconductor, typically silicon. The voltage of the covered gate determines the electrical conductivity of the device; this ability to change conductivity with the amount of applied voltage can be used for amplifying or switching electronic signals. The MOSFET was invented by Egyptian engineer Mohamed M. Atalla and Korean engineer Dawon Kahng at Bell Labs in 1959. It is the basic building block of modern electronics, and the most frequently manufactured device in history, with an estimated total of 13 sextillion (1.3 × 1022) MOSFETs manufactured between 1960 and 2018.
