Design elements - Telecom

The vector stencils library "Telecom" contains 20 telecommunication icons. Use it to design your IT and telecom illustrations and infographics with ConceptDraw PRO diagramming and vector drawing software.
"Telecommunication is the transmission of signs, signals, writings, images and sounds or intelligence of any nature by wire, radio, optical or other electromagnetic systems, as defined by the International Telecommunication Union (ITU).
Telecommunication occurs when the exchange of information between communication participants includes the use of technology. It is transmitted either electrically over physical media, such as cables, or via electromagnetic radiation. Such transmission paths are often divided into communication channels which afford the advantages of multiplexing. ...
Modern technologies for long-distance communication usually involve electrical and electromagnetic technologies, such as telegraph, telephone, and teleprinter, networks, radio, microwave transmission, fiber optics, and communications satellites." [Telecommunication. Wikipedia]
The telecommunication icon set example "Design elements - Telecom" is included in the Computers and Communications solution from the Illustration area of ConceptDraw Solution Park.

This line graph sample shows the circuit efficiency for telecommunications. It was designed on the base of the Wikimedia Commons file: Circuit efficiency Erlang B.png. [commons.wikimedia.org/ wiki/ File:Circuit_ efficiency_ Erlang_ B.png].

"In telecommunications systems, trunking is the aggregation of multiple user circuits into a single channel. The aggregation is achieved using some form of multiplexing. Trunking theory was developed by Agner Krarup Erlang, Erlang based his studies of the statistical nature of the arrival and the length of calls. The Erlang B formula allows for the calculation of the number of circuits required in a trunk based on the Grade of Service and the amount of traffic in Erlangs the trunk needs cater for. ...
In order to provide connectivity between all users on the network one solution is to build a full mesh network between all endpoints. A full mesh solution is however impractical, a far better approach is to provide a pool of resources that end points can make use of in order to connect to foreign exchanges. ...
The Danish mathematician Agner Krarup Erlang is the founder of teletraffic engineering. Erlang developed the fundamentals of trunking theory while investigating how a large population can be serviced by a limited number of servers. Trunking theory leverages off the statistical behaviour of users accessing the network, these characteristics discussed in the assumptions of the Erlang B equation."
