Radio-frequency Technician Jjobs

Radio-frequency (RF) engineering is a subset of electronic engineering involving the application of transmission line, waveguide, antenna and electromagnetic field principles to the design and application of devices that produce or utilize signals within the radio band, the frequency range of about 20 kHz up to 300 GHz.

It is incorporated into almost everything that transmits or receives a radio wave, which includes, but is not limited to, mobile phones, radios, Wi-Fi, and two-way radios. RF engineering is a highly specialized field that typically includes the following areas of expertise:

1.   Design of antenna systems to provide radiative coverage of a specified geographical area by an electromagnetic field or to provide specified sensitivity to an electromagnetic field impinging on the antenna.

2.   Design of coupling and transmission line structures to transport RF energy without radiation.

3.   Application of circuit elements and transmission line structures in the design of oscillators, amplifiers, mixers, detectors, combiners, filters, impedance transforming networks and other devices.

4.   Verification and measurement of performance of radio frequency devices and systems.

To produce quality results, the RF engineer needs an in-depth knowledge of mathematics, physics and general electronics theory as well as specialized training in areas such as wave propagation, impedance transformations, filters and microstrip printed circuit board design.

Radio-frequency engineers are specialists in their respective field and can take on many different roles, such as design, installation, and maintenance. Radio-frequency engineers require many years of extensive experience in the area of study. This type of engineer has experience with transmission systems, device design, and placement of antennas for optimum performance. The RF engineer job description at a broadcast facility can include maintenance of the station's high-power broadcast transmitters and associated systems. This includes transmitter site emergency power, remote control, main transmission line and antenna adjustments, microwave radio relay STL/TSL links, and 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 optimum performance within the piece of equipment being developed.

What Are RF Systems Technicians?

Radio frequency (RF) systems technicians, also known as radio mechanics, install, maintain, and upgrade RF systems, such as wireless Internet access points, cellular telephone antennas, satellite systems, amplifiers, two-way radios, and other radio equipment. Other tasks may include testing RF systems and signal strength, assembling systems, maintaining records, and instructing customers on how to properly use the equipment.

Most RF technician jobs involve driving to client locations. Such technicians should be comfortable with heights. There is some risk of injury associated with this career due to the fact that technicians often work on towers or other high places, work closely with electricity, and use a range of potentially dangerous tools to complete their tasks. The majority of telecommunications technicians, such as RF systems technicians, work full-time, although overtime, on-call, evening, night, and weekend hours are a possibility.

Steps for RF Systems Technicians

How can I become an RF systems technician?

Step 1: Complete Postsecondary Training

The first step is to complete postsecondary training. Although there are no set educational requirements for becoming a radio frequency systems technician, employers may prefer to hire candidates with at least an associate's degree. Some schools offer associate's degree programs in electronics engineering technology with wireless options. Other options include earning a degree in electrical engineering technology or computer science.

Step 2: Gain Experience

The next step is to gain experience. Although it's possible to gain entry-level employment in RF systems technology, many employers prefer hiring candidates with prior experience working with design, installation, troubleshooting, and repairing RF systems and related technologies. Gaining experience in a related area can help give aspiring RF systems technicians the familiarity with the equipment and technology that they'll be working on in the field. Entry-level technicians often work as part of a team and with substantial supervision. Some employers also require on-the-job training for new RF systems technicians.

You will want to look for opportunities to become professionally certified in the field. Voluntary certification may increase job opportunities, since the credentials demonstrate professional expertise. Some available options include the RFID certification issued by the RFID Professional Institute, wireless certification issued by Anritsu, and various certifications issued by iNARTE. Although the requirements for each credential vary by organization, candidates generally need to have some prior experience and take a certification exam.

You will also want to research certification renewal requirements. Some organizations may require candidates to renew the certification periodically. Continuing education, training, or work experience may be a condition of keeping certification current.

RF systems technicians have training and/or education after high school. They are highly skilled and work in some dangerous situations, and they earn a median annual salary of $51,660.

Whait is Network Operation Center (NOC)

Network Operations Center – Definition

A network operations center (NOC) houses the equipment and personnel for monitoring a network of computers, servers, mobile devices and Internet of Things devices, aka smart devices from a centralized location. The NOC has the high-functional infrastructure with automatic alerts that notify technicians about the issues across the network.  The overall function of a NOC is to maintain the network uptime with smooth & uninterrupted operations.

What do People Monitor in a Typical NOC?

NOC Engineer or NOC Technicians are accountable for maintaining 100% network uptime by monitoring network 24/7/365. They ensure the connectivity of an IT system is glitch-free so that the productivity& profitability of the business is not compromised. They are also responsible for monitoring every net flow, hop, server and endpoint attached to a Managed Service Providers (MSP’s) client networks.

• They keep a close eye on network’s infrastructure to ensure the system’s uptime is not compromised due to malware, network errors or other network related issues.
• They deal with the complex networks and troubleshoot if required by following the standard procedures.
• The high functional NOC help technicians in identifying problems across the network before it occurs.

Network Operations

What is Network Operations? & Best Practices

Network Operations refers to the activities performed by internal networking staff or third parties that companies and service providers rely on to monitor, manage, and respond to alerts on their network's availability and performance. Staff that have primary responsibilities for network operations are often called network operations analysts or network operations engineers.

A Network Operations Center, often called a NOC (pronounced "knock"), is typically a centralized location where the network operation staff provides 24x7x365 supervision, monitoring, and management of the network, servers, databases, firewalls, devices and related external services. This infrastructure environment may be located on-premises and/or with a cloud-based provider.

Some key Network Operation activities are:

• Network monitoring
• Incident response
• Communications management (Email, voice, & video)
• Performance, quality, and optimization reporting
• Software/firmware installation, troubleshooting and updating of network elements
• Patch management
• Backup and storage
• Firewall management
• Intrusion Prevention System (IPS) and other security tool deployment and monitoring, in collaboration with Security Operations
• Threat analysis and blast radius analysis in collaboration with Security Operations
