What is a network engineer?

 First of all, let's define the terms. A network engineer is a specialist responsible for creating, configuring and maintaining the company's internal computer networks, as well as for interacting the company's IT infrastructure with external networks. "Networkers" must have a serious level of knowledge in the field of design and maintenance of networks, but their work will include elements of server administration and programming.

It is required to understand local networks, equipment and software solutions used in the company to manage the network component of IT systems. All this is provided only by a high level of qualifications of a network specialist: gaps in education and practical experience can be very expensive for a company, and given the depth of integration of business processes in a digital environment, the scale of potential losses is sometimes difficult to imagine, and it is better to avoid them even in theory ...

The value of certification

The development of any career depends on a specific person, in particular on awareness of choice, focus on results and readiness for difficulties. When building a career in the IT field, it is worth highlighting priority areas and tasks. I started my self-education process with a successful career in a completely different field, not related to IT and telecommunications.

The first, intermediate, goal on the career path of a network engineer can be called the certification of one or more vendors of network equipment. If we consider the most popular vendor, then gaining knowledge at the CCNA level (the first level in the Cisco certification system) is an objective entry barrier for working as a network engineer.

This certification does not indicate a specific level of knowledge, but indicates a basic understanding of working with network equipment. For people who are just starting a career with no work experience, having a certificate can be a good help when applying for a job.

Taking a CCNA course on the basis of one of the training centers gives certain knowledge, but from the point of view of the experience gained, the maximum result can be obtained only with the already existing knowledge, by structuring it on the course and receiving answers to already formed questions. A lot depends on the teacher on the course, it is worth looking for a teacher not only with his own high qualifications, but also with good teaching skills.

What job opportunities does a telecommunications engineer have?

Telecommunications engineers often work as operators, manufacturers, and service providers. However, there are also other outputs that should be known:

Banking. Engineers intervene in disciplines such as  automatic trading  . In other words, the creation of robots that operate autonomously and in real time on the different stock markets. In addition, they are responsible for the information systems of the banks.

Logistics and Transportation. In this case, they deal with product tracking systems, fleet tracking, smart highway creation, vehicle-to-vehicle communication, etc.

Image. Are you one of those who enjoys digital or 3D television to the fullest? Well, behind these achievements there is always a telecommunications engineer. On the other hand, image processing can also be used to carry out medical diagnoses.

Defending. In the field of defense, telecommunications have diverse applications. For example, transparent materials (not detectable by radar) or augmented reality equipment for soldiers.

What does and where does a telecommunications engineer work?

The profession of a telecommunications engineer focuses on providing technical solutions in the transmission and reception of signals and the interconnection of networks for a company or organization.

Researching innovative products, getting updated on everything related to technological products and strengthening the ability to solve problems are some of the most important tasks of a telecommunications engineer .

The term "telecommunication" refers to communication at a distance , generally through the propagation of electromagnetic and optical waves. 

A telecommunications engineer is responsible for the design, research, and development of communications systems that are delivered via cable and satellite, mobile phones, radio waves, the Internet, and email.

They use a variety of equipment and means of transportation to design telecommunication network infrastructure. The most common used in today's cable telecommunications are coaxial cables, optical fibers, and twisted-pair cable .

Radio frequency engineers

 Radio frequency engineers are specialists in their respective fields and can take on many different functions, such as design, installation, and maintenance. Radio frequency engineers require many years of extensive experience in the area of ​​study. This type of engineer is experienced in broadcast systems, device design, and antenna placement for optimal performance. The RF engineer job description at a broadcast facility may include maintaining the station's high-power broadcast transmitters and associated systems. This includes emergency power transmission site, remote control, main transmission lines and antennas settings, microwave radio relay STL/ TSL links and much more.


In addition, a radio-frequency design engineer must be able to understand electronic hardware design, circuit board material, antenna radiation, and the effect of interfering frequencies that prevent optimal performance within the piece of equipment being being developed.


RF Technician Job Description

Radioelectronics

Radio electronics deals with electronic circuits that receive or transmit radio signals.

Typically these circuits must operate at radio frequencies and power levels, which places special restrictions on their design. These limitations increase in importance with higher frequencies. In microwave frequencies, the reactance of signal traces becomes a crucial part of the physical layout of the circuit.

Radio Electronics Topic List:

RF oscillators : PLL , voltage controlled oscillator

Transmitters , transmission lines , RF connectors

Antennas , antenna theory , the list of antenna terms

Receivers , tuners

amplifiers

Modulators , demodulators , detectors

RF filters

RF shielding , Groundplane

PCB design guidelines

DSSS , noise power

What is the typical job of a radio frequency technician?

Well, the RF technician is in charge of managing all the wireless systems that he has in the show, be they microphones, be they in-ears , management of the walkies that are being used in the show or in the event, the intercom systems ... coordinate everything this.

You must make a work table so that all those frequencies are not stepped on and you can work without any problem. This is the main job of the radio frequency technician.

If radio frequency doesn't work well at an event, what can happen?

If the radio frequency does not work well the event is chaos.

Because the bad thing about radio frequency is that when something goes wrong you don't know where the shots are coming from and you don't know what to do. So you have to have the resources to get ahead without the breakdown being very obvious.

There are always going to be problems: a microphone is cut, it falls, a connection to the microphone itself breaks ... this is inevitable.

But how to solve it and how to get out of the fast track is not a task for which everyone is prepared and you have to have a certain solvency when it comes to getting ahead.
