Structure of a telecommunications system

A telecommunications system is made up of the information sender , the transmission channel and the information receiver . The sender is a device that transforms or encodes the message into a physical phenomenon: the signal. The channel or medium transmits this signal, and the receiver does the reverse process to the transmitter to obtain the information.

The functions of the transmitter always involve, in one way or another, the coding of the information and its adaptation to the channel. The transmission channel, for physical reasons, modifies or degrades the signal in some way in its path. The receiver has to perform the functions of detecting the signal, recomposing it and decoding it in order to extract the information. In this process there is always a possibility of error, which telecommunication engineering tries to minimize.

As a familiar example of a telecommunication system, we can consider voice communication between people. This case we can decompose it like this:

The issuer: person who speaks. The consciousness of a person wants to transmit a message (idea or concept), the brain encodes it in words of a language and "sends" it to the mouth to be pronounced, finally being encoded in a series of sounds produced by the strings vowels and organs of phonation.

The medium is made up of the layer of air that exists between the two participants. The vibrations emitted pass through it, which can be affected in different ways by ambient noise, echoes, other conversations ...

The receptor is made up of the ear / brain assembly. The ear converts the vibrations to electrical impulses, which are processed by the [brain] in order to extract the message, from which it informs the "consciousness".

In other cases, as an example, communication can be made between faxes, telephones, keyboard-printer, camera-screen ... and the communication channel can be made up of wires, radio waves, fiber optics, satellite ... .

Depending on the direction of transmission, communication can be classified as unidirectional (from sender to receiver) or bidirectional (communication in both directions).

The topology of a telecommunication can be point-to-point and point-to-multipoint (called broadcast in the extreme case with many receivers and with unidirectional transmission).

The intrinsic problem of communication occurs when we want to transmit information quickly or between two distant points, or both at the same time. This is the case that has led to the development of telecommunication engineering

RF Technician Salary

Radio frequency and microwave engineer

This professional is in charge of the design and manufacture of radio frequency and microwave electronic equipment that will be installed in satellites, mainly telecommunications.

The activity of this occupation ranges from the electronic design of the system to the construction of prototypes that are put to the test using simulators and the manufacture of a final model that works satisfactorily, once the tests have been passed and attending to the initial needs raised. You work from specific customer assignments, which is why you will have to develop an ad hoc design to meet your requirements.

Chores

Identify circuit alternatives (possible circuit architectures) and study the arrangement of their components.

It performs computer operating simulations and uses iterative calculation procedures (repetition of the calculation by successive approximation) until reaching the solution that best suits the requirements that the system must satisfy.

Oversees the work of technical prototyping teams during the prototyping process.

It develops the testing process and, depending on the results obtained, corrects the model until the final format is achieved, having to carry out continuous reviews or even draw up a quality control protocol to apply it to the developed system.

Choose the model that will eventually be developed.

Prepare the design documentation (called Design Report), which records the entire process of building the final prototype.

What is a RF Technician

It is important to train new professionals who dominate the world of RF, that it is not a void that nobody knows or that touches the monitor technician or the microphone technician "by waste".

That the technicians are trained and know that RF is important for the day to day of any musical show; no matter how small the show there will always be a wireless mic.

Well, a wireless microphone does not give problems, and if we put two together the problem begins; three four five…. the problem grows.

And when we already have 20 microphones we have to keep many things in mind, have everything very clear, know what to do, how to place antennas, position in-ear antennas, mic receiver antennas, in short, all this grows and becomes a ball very big.

We must enter into this work and we try to instill this unknown but very useful facet in the audiovisual sector.

What types of radio frequency equipment are usually used in the classes you teach?

Well, the equipment that we use in Trade's radiofrequency classes are the equipment that is in the sector, those that are used in the sector and that we can find in any event, in any show , in any presentation, etc.

We use top-notch equipment that we can "mess with" and drive with regularly. Here, then, we don't have 20 devices but we have 6 wireless devices, 4 in-ears ... but the interesting part of all this is knowing RF and combining, combining devices from different brands.
