RF Tech

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.

what does a security consultant do

 The function of the security consultant is to advise the company on the security policy and the most appropriate systems to apply. He is in charge of carrying out an analysis of the risks on the assets associated with the people in the company he advises (for example, possible losses of assets or illegal actions of the staff), so that they can act in the event of a problem with the solution best suited to the needs and resources of the company. It is a generic occupation that can create more jobs if the professional specializes well in a specific job or sector.

Chores

It should be noted that each of these tasks can become a specialty of the consultant and its own professional profile.

Identify the strengths and weaknesses of the company in terms of security. Knowing how the company works requires an analysis of the organization and the identification of the needs and gaps it has, both in the general field and in the security aspect.

Identify the risks and threats that can pose losses to the organization. Based on knowledge of the organization and the environment, it establishes the risks that may pose a danger to the organization.

Advises in the definition of the security policy of the company. It helps the company management to define the security policy to be followed in accordance with the characteristics of the organization and the regulations that must be met.

He plans security systems that will later be implemented and maintained by himself or by specialists and technicians. Define which are the best security systems, depending on the needs and resources of the company.

Verify the system once it is implanted. Once the security system is installed, check that it is working properly and that it is being used properly.

Inspects existing security systems. It evaluates the systems that are already installed to assess whether they are adequate to the current needs of the company, that is, if the system covers the current risks that the company may suffer. It is important to carry out inspections, since companies are dynamic and over time a security system can become obsolete or not meet the needs.

Verify the quality of a security system, according to the needs and characteristics of the organization. This work is closely related to inspection. A security system not only has to respond to the needs of the moment, but it also has to respond with quality, for example, an alarm system cannot generate false alarms continuously, since it has very harmful effects.

As an external consultant, he prepares, coordinates and streamlines the development and execution of crisis plans.

It clarifies and defines the objectives to be achieved in each risk and measure applied.

It informs about the ideal criteria for controlling the company's information, tabulating the appropriate distribution levels and advising on the best distribution channels.

Perform congruence analysis on security projects and applications.

Collaborates in the definition and implementation of continuity and disaster recovery systems.

Participate in the definition of desirable profiles in the hiring of strategic business personnel.

Conduct safety studies on specific topics. It develops specific studies or investigations that it can receive to analyze a specific or specific situation that the company has to solve. For example, you can do a one-off analysis on the illicit use of computers by someone on your staff.

full stack network engineer salary

 According to the 2017 Hays Survey , 40% of those surveyed consider that young people are poorly prepared to go out to the labor market after finishing their studies, while 47% consider that they are quite prepared.

Perhaps more relevant is the fact that 9 out of 10 respondents say that there is a gap between the preparation of young people and what companies demand .

Engineer, where are you?

Technology-related positions are in high demand. Thus, for example, the demand for IT engineers has skyrocketed in Barcelona under the protection of start-ups (there are more than 1,100 according to a study by the Generalitat) and with the implementation of multinational technology centers, which cannot meet the demand that they themselves generate.

In fact, 85% of the supply of jobs related to new technologies is concentrated in Madrid and Barcelona.

Network Engineer Skills to Know

network engineer skills

1. Customer Relations

Depending on the nature of the company or organization you’re employed in, you may be expected to troubleshoot networks for clients or handle front-end network issues. This involves excellent communication skills, the ability to explain technical issues to non-technical individuals, and the ability to understand and build a relationship with the clients you work with. 

2. Analytics and Troubleshooting

Network engineers solve problems within the network before and after they arise. It’s crucial to have the analytical skills to understand where a problem is originating from, and have a dedicated troubleshooting process to effectively solve the issue and prevent it from happening again.

3. Firewalls and Security

Network security is crucial, especially if the network in question handles regulated data. While more organizations have a dedicated IT security officer, end-to-end security means that everyone on an IT team needs to be involved in keeping the network secure. As well, network engineers often deploy and maintain firewalls within the network. 

4. Networking

Networking and routing skills are integral to the job. Engineers need to be familiar with different types of networks and architectures (including WAN, LAN, SD-WAN, SD-branch, and so on) and how they can be integrated into an existing system. As new network types emerge, it’s crucial to stay educated on new developments.

5. Programming Languages

Engineers should know general-purpose scripting languages such as Python, Ruby, and Perl, which are the most popular for enterprise-grade networks. It’s useful to know automation-friendly languages such as Java, Terraform and Ansible, as more network functions become automated. As well, since more networks are using open-source networking resources, Bash for Linux is becoming a must.

6. Hardware and Infrastructure

Part of a network engineer’s duties includes making calls on what hardware the network and its function will reside on. It’s key to be aware of the major network hardware vendors and what products they offer; while you may not be making the purchase decisions directly, you will be expected to know the networks’ needs that form the basis for these purchase decisions. As well, you will be expected to work with and maintain the network infrastructure. 

7. DNS

Domain-name system (DNS) is the basis for the internet as we know it, and is crucial to the operation of an internet-connected network — which is the basis for most modern enterprise networks. If the DNS is down, then it takes the network with it, which makes knowing how to troubleshoot it critical in a connected environment.

8. IoT

IoT is predicted to make a huge impact on enterprise network traffic, infrastructure, and security, as more businesses come to rely on IoT devices. While generally associated with 4G and 5G networks, certain types of network architectures, such as SD-branch, will use WiFi or other non-mobile connections to support their IoT ecosystems. Security is an important tie-in to this, since IoT devices are notoriously breachable. 

9. Virtualization and Automation

Virtualization is the name of the game for today’s networks — namely SD-WAN. Engineers must be able to work with automated network functions so they can best allocate network and IT resources. You may have to help develop automated functions yourself, though usually an automation engineer will be in charge of this.

10. MPLS

While SD-WAN has been augmenting or replacing MPLS for enterprises, many still rely on MPLS to ensure reliability and security in the network, making MPLS a critical network engineer skill. Engineers should know how to work with an MPLS-exclusive network, and, more commonly, hybrid WAN networks.

How to Become a Network Engineer

 So you want to be a network engineer. Where do you start?

Here’s the good news — network engineers are in high demand. Companies are investing in newer, faster technology and mobile networks every day, increasing the need for highly trained network engineers.

Network engineering is a fast-growing occupation. The Bureau of Labor Statistics estimates that network engineer employment is projected to grow 6 percent from 2016 to 2026, above average for all occupations.

What Is a Network Engineer?

Network Engineer
