  1. Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field.

  3. History of telecommunication. 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.

    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. Traditional telephone calls continue to be the industry's biggest revenue generator, but thanks to advances in network technology, telecom today is less about voice and increasingly about text and images. High-speed in

    Of all the customer markets, residential and small business markets are the toughest. With hundreds of players in the market, competitors rely heavily on price; success rests largely on brand name strength and investment in efficient billing systems. The corporate market remains the industry's favorite. Big corporate customers are concerned mostly about the quality and reliability of their telephone calls and data delivery while being less price-sensitive than residential customers. Multinationa

    The telecommunications sector has seen a large increase in the recent years. Whereas in 2015 there were 3.3 billion active mobile broadband subscriptions worldwide, in 2020 there were around 7.7 billion. This increase was due, in part at least, to the deployment of 4G LTE. During the COVID-19 pandemic, telecommunications supported the fight against the virus and the resilience of economy by various developments, including supporting the developments of heat maps showing the expansion of the viru

    A telecommunications network is a group of nodes interconnected by telecommunications 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. Multiple nodes may cooperate to pass the message from an originating node to the destination node, via multiple network hops. For this routing function, each node in the network is assigned a

    In general, every telecommunications network conceptually consists of three parts, or planes: 1. The data plane carries the network's users' traffic, the actual payload. 2. The control plane carries control information. 3. The management plane carries the operations, administration and management traffic required for network management. The management plane is sometimes considered a part of the control plane.

    In analogy to the improvements in the speed and capacity of digital computers, provided by advances in semiconductor technology and expressed in the bi-yearly doubling of transistor density, which is described empirically by Moore's law, the capacity and speed of telecommunications networks have followed similar advances, for similar reasons. In telecommunication, this is expressed in Edholm's law, proposed by and named after Phil Edholm in 2004. This empirical law holds that the bandwidth of te
