Today the landline phone is perceived almost as a relic of the last century. It is not as convenient to use it as a mobile one, it is more cumbersome and you have to pay for communication services not so little. There is an opinion that the landline telephone will soon become a thing of the past. And the generation born in the 21st century no longer knows and understands very well what a landline telephone is.
A bit of history
The idea of transmitting voice messages at a distance using wire communication was first put forward in 1854 by S. Bursel. It was he who first used the term "telephone". But his idea was not implemented.
In 1861, physicist I. Reis designed a device that made it possible to transmit sounds at a distance by means of wires. It consisted of a microphone, speaker, and a galvanic battery that served as a power source.
But Alexander Bell is officially considered the inventor of the telephone. It was he who patented in 1876 a device that made it possible to transmit speech and other sounds at a distance of no more than 500 m. Initially, the device had one tube, which was used to transmit and receive speech.
Later, the phone was equipped with two handsets, one of which was built into a microphone, the other - a speaker. Later, these devices again "merged" into a tube, which could be held at the ear and at the same time speak into it. Further improvements made it possible to equip the telephone with a carbon microphone, a capacitor, and a system of permanent magnets.
But the essence of telephone communication remained the same: for its operation, it was necessary to lay a cable through which a signal came from the apparatus to the telephone exchange, and from there a signal went to the telephone of the called subscriber. At first, the stations were serviced by people: the telephone operators took the call and manually switched the subscriber to the desired line. In the XX century, telephone exchanges were automated, and the automatic telephone exchange was already performing the "duties" of telephone operators in an automatic mode.
Landline telephone now
Now many owners of landline phones refuse them or are thinking about it. Indeed, why pay for a not-so-convenient wired connection if you have a mobile phone? However, it is too early to write off stationary devices, because the need for them still exists.
Landline telephones are actively used in organizations and institutions where you have to make a lot of business office calls - it is cheaper than providing each employee with a corporate SIM card and paying for services using them.
Elderly people who are accustomed to using a stationary device are in no hurry to refuse this type of service, even if they have a mobile phone. Indeed, for a person of age, with limited mobility, the telephone sometimes becomes the only means of communication with the outside world: they can not limit themselves in time, communicating with relatives and friends.
It is also more profitable to make long-distance calls by landline phone, if a person does not have a computer with Skype installed on it.
The quality of communication when using a stationary device is also always stable and sometimes compares favorably with the quality of a mobile one.
So the landline telephone is not yet a relic of the past, but a completely viable device. In addition, it has become much more convenient to use. The latest generation phones have tone dialing, digital sound processing. Modern tubes can be freely carried anywhere in the room and talk in a comfortable environment.
