The telecommunication industry handles services transferring or exchanging information through cables, telephone, radio or television across significant distances. It is has been a booming contributor to world economics.
This industry is growing rapidly due to substantial economic growth and mounting population.
Changes in telecommunications
In olden era, telecommunications industry was to make use of visual signals including ns, smoke signals, semaphore telegraphs, signal flags, and optical heliographs, or audio messages such as coded drumbeats, lung-blown horns, and loud whistles.
But the telecommunications industry has also changed its pattern with time. Now it involves the use of electrical devices like the telegraph, telephone, teleprinter, radio and microwave communications, including fiber optics and their associated electronics, along with the use of the orbiting satellites and the Internet. This is also considered as the fastest means of transferring information.
There are 3 key units that are always present in some form in the telecommunication system:
- A transmitter that takes information and converts it to a signal.
- A transmission medium, also called the “physical channel” that carries the signal. An example of this is the “free space channel”.
- A receiver that takes the signal from the channel and converts it back into usable information.
Factors that boost telecommunications
The two major factors which are responsible for the growth of telecommunications industry are use of modern technology and market competition.
Modern technologies involve the use of many products of which there is one product called optical fibers, which are being used as a medium of data transmission rather than using coaxial or twisted pair cables. It is able to transmit a high volume of data and is easier to maintain and install. On the other hand the telecommunications industry becomes a booming industry with the use of communication satellites. The use of mobile network plays an important role in enhancing the telecommunications industry.
Telecommunications industry to become a digitized one, with the use of ISDN (Inter Services Digital Network), due to which the speed and quality of digital communication has been enhanced in the industry.
Seeing the drastic growth in the industry many leading companies are interested to invest in this telecommunications industry.
Telecommunication industry has created huge employment opportunities, most of which involve large establishments, even though there are some small establishments, where a large number of small contractors are engaged.
55% of the employees are occupied in office and administrative support occupations, while others are engaged in industry related to installation, maintenance, and repair.
