The adjective repeater , which comes from the Latin word repetītor , is used to describe the one or thing that repeats . The action of repeating, meanwhile, consists of expressing or doing something again .
The term is usually used to refer to a student who repeats a subject or course . You can also qualify someone who says the same thing that another person has already said before.
For example: “I am the only repeating student in my course” , “I don't want you to be my repeater, I want you to draw your own conclusions” , “This school has a policy of not enrolling repeaters” .
Primary and secondary school students are subjected to a series of pressures that adults often do not perceive. First of all, we must keep in mind that they are in different fundamental stages of cognitive and physical development, and the changes they go through over the more than ten years that this elementary education covers are not far from being chaotic for them: they begin with basic notions. basics of the language, but upon completion they are ready to face a university career.
In the midst of this intense learning experience they go from being children to young people, discovering their sexuality and forming their personality. It is not strange that some cannot face all this, and that they are left behind, they become repeaters. The worst thing is that the impossibility of passing the grade stigmatizes them, brings upon them the ridicule of their peers and the disappointment of their elders.
In the field of television , telecommunications and similar sectors, a device that captures an electromagnetic signal and retransmits it amplified is called a repeater.
The repeater can be an analog device whose function is to amplify the input signal , regardless of whether this signal is analog or digital. It can also be digital equipment that amplifies or carries out another task on the digital signal that it is responsible for retransmitting.
Repeaters were born to avoid mountains or other obstacles in the transmission of signals and to allow signals to go further, crossing great distances . The characteristics of these elements vary depending on their specific purpose.
There are repeaters that retransmit TV or radio signals, for example. Others allow you to repeat WiFi signals, increasing their range.
It should be noted that, in the case of repeaters that work with digital signals, they are usually called regenerators . This is because the output signal is actually a signal that is regenerated from the input .
Repeaters are very useful for almost all users of these services, although they become essential for those who live very far from the main antennas or behind important obstacles. Such is the case of rural areas in terrain with high elevations, where it is very difficult for television and Internet signals to reach.
Speaking specifically about the WiFi repeater, it is also called an amplifier since it performs both tasks: it takes the signal that arrives in your area and amplifies it, to improve its range. In other words, they are designed with the goal of providing a group of users with better coverage than they would receive without their help. Generally, it fulfills these functions to more effectively propagate the signal it receives from the wireless router , which can also be complemented with external antennas that are placed outside the home.
It is worth mentioning that the use of a Wi-Fi repeater is common both inside and outside buildings, whether in the industrial, commercial or home environment . Inside a very large building or with walls that are too thick, the signal emitted by a wireless router can weaken considerably and not reach all the devices that need to connect to the Internet. For these cases, interior repeaters are used.
