     what does telecommunications mean---Definition

OKorder what does telecommunications mean

     Telecommunications refers to the use of electronic technology to transfer information between different sites. For example: Radio, telegraph, TV, telephone, data communication and computer network communication, etc.. Telecommunications is an important pillar of the information society. Whether in human social and economic activities, or in the daily life of the people, we can not do without telecommunications which is efficient and reliable means. 

     what does telecommunications mean---Constitution 

     The basic elements of communication system includes a transmitter, channel and receiver.

     what does telecommunications mean---Development history

     In 1948, Shannon published the paper "the mathematical theory of communication",  and this paper created the mathematical theory of communication system. Information theory allows us to estimate the capacity of the channel's bandwidth and signal to noise ratio.

In the times of the paper, the telecommunication system is mainly based on analog circuit system. Since then, with the development of digital integrated circuits, the design of the telecommunication system can make full use of the theory of information theory to improve the performance. Thus, digital signal processing has become a new area.

     what does telecommunications mean---Industrial characteristics

     Scale:Telecommunications has become an important way to overcome the obstacles of time and distance.

     Standardization:Under the premise that the communication mode is widely used, the phase inversion of the encoding and the decoding process requires the standardization of telecom.

     what does telecommunications mean---Service features

     Persistence:Telecom service is a kind of uninterrupted communication platform, the need to exchange the demand at any time, the information service should be in the standby state even when the customer does not need the service.

     Externality:The popularization rate of Telecom is positively related to its value. The overall value of telecommunication services is greater than the sum of the parts.


Telecommunication services and technologies must be used in uniform standards and must ensure the compatibility of interfaces.

     Natural monopoly:This is due to the huge cost of telecommunications industry is huge, it is not to repeat investment. Therefore, its basic services should not be fully competitive.

     Cost decline:

Marginal cost of telecommunication services tends to zero, so the telecom customer enough reasonable fees should be for rent, and occupation of lines at a time and distance has nothing to do. Charge is a traditional industry bias in terms of time and distance.
