The True Value of the Top Wireless Certifications

The Information Technology (IT) industry is famous for its plethora of industry-standard certifications. Engineers can choose from certifications in every aspect of the multitude of different facets within this huge field. The top wireless certifications are often an overlooked goldmine.

Generally, people pick a favorite part of information technology and deep-dive into it, eventually becoming an expert in that field. It is said that it is impossible for any one person to know everything about IT!

Unseen Benefits of Wireless Certifications

Industry certifications are vital in that they enhance standard educational credentials (Bachelors, Masters, etc.). They are the perfect way to prove to employers – for purposes of gaining a new job or being promoted within the same company – that the engineer’s skill set, in a given aspect of technology, is cutting edge.

Certifications also have the added bonus of indicating that the engineer has an enthusiastic interest in that particular aspect of technology because they have taken it upon themselves to put in the extra effort and become certified. From an employer’s perspective, an enthusiastic person is more likely to do a good job – so, certifying has the innate benefit of showing a degree of passion as well as the obvious one of being a certification that proves knowledge and capability.

Although it is so vitally important, the Wireless aspect of IT certifications is often overlooked.

Function of Wireless

What function does Wireless perform? Well, at a very basic level, any technology that is not connected with wires… is wireLESS. We have all heard of “WiFi”, but how many of us really know how vital, to business enterprise, knowing how to run a wireless network actually is?

Enterprise networks are a lot more complicated than home networks. In a business setting, precautions have to be taken such that visitors cannot access sensitive company files however, allowances must be made for seamless – but secure – access for their laptops and smartphones.

When you add in all the employees who also need wireless access to the network, and at various permission levels, the whole thing becomes highly complex.

IT Engineers with top wireless certifications are in-demand

The idea of employing engineers who possess IT industry top Wireless certifications, is very reassuring to an employer. They can then rest assured that their wireless network engineer really knows their stuff and can act as the first line of defense in safeguarding the business’ information.

With the amazing growth of “smart” pretty-much-everything, wireless networks are becoming bigger and more complicated every day, and the demands upon them are growing at an exponential rate.

As more and more companies catch the vision and update the way they interact in-house as well as with their customers, more Wireless engineers will be needed – especially well-trained Wireless engineers – who are the modern-day “knights”, protecting the business “castle”.

Wi-Fi Myth Series - Myth #13: Mesh is ALWAYS The Best Solution

By Rie Morgan • September 10, 2026

Mesh Wi-Fi has developed quite the reputation: Need coverage in the far end of the building? Mesh. Can’t get Ethernet to an access point? Mesh. Dead spot upstairs? Mesh. Need Wi-Fi in the warehouse, courtyard, annex, garage, loading dock, or that mysterious conference room where RF signals apparently go to die? Mesh. And there’s a reason for the enthusiasm. Mesh networking can be extremely useful: it can extend connectivity into places where running cable is difficult, expensive, disruptive, or simply impossible. Modern mesh systems can dynamically select paths, recover from connectivity changes, and provide remarkably capable wireless backhaul... but that doesn’t mean mesh is automatically the best architecture. Sometimes the best mesh network is the one you don’t build!

Wi-Fi Myth Series - Myth #12: Auto Channel Selection ALWAYS Knows Best

By Rie Morgan • August 28, 2026

Automatic Channel Selection sounds like one of those features we should simply be able to trust: the APs monitor the RF environment, the Controller gathers data, an Algorithm considers interference, utilization, neighboring APs, channel availability, and other metrics, then Radio Resource Management (RRM) does its “thing” and selects the best channels. Wonderful! One less problem for the wireless engineer to worry about... except RF rarely cooperates with anything quite that neatly! Modern RRM systems are remarkably capable, and automatic channel selection can dramatically simplify the management of large wireless environments, but an algorithm can only make decisions based on the information it collects, the parameters it has been given, and the objectives it has been designed to optimize. That makes automation a powerful engineering tool. It does not make it the engineer.

Wi-Fi Myth Series - Myth #11: Interference Is Always Someone Else’s Wi-Fi

By Rie Morgan • August 20, 2026

When Wi-Fi performance suddenly deteriorates, interference is often the first culprit to be suspected and, when this (interference) enters the conversation, attention tends to turn immediately toward neighboring Wi-Fi networks. “Someone must have installed another AP.” “The office next door is probably using our channel.” “There are too many SSIDs around here.” Sometimes, this diagnosis is exactly right, but RF interference has a much larger cast of characters than just neighboring APs. In fact, some of the most frustrating wireless problems occur when the interfering device isn’t speaking 802.11 at all! The spectrum doesn’t particularly care whether the energy occupying it came from an enterprise AP, a Bluetooth headset, a microwave oven, or something considerably stranger. To a Wi-Fi radio trying to communicate, unwanted RF energy is simply unwanted RF energy. Wi-Fi Has to Share the Neighborhood The 2.4 GHz band has always been something of an RF “community center”. Wi-Fi operates alongside Bluetooth, Zigbee and other technologies, while various consumer, industrial, medical, and electronic devices may also generate energy within or around the same spectrum. Microwave ovens are perhaps the most famous example. Their emissions can interfere with 2.4 GHz Wi-Fi, particularly when clients are operating nearby. Bluetooth devices, cordless equipment, wireless cameras, sensors, and other transmitters can also contribute RF energy. Some interferers transmit continuously. Others appear periodically. Some hop frequencies. Others produce wideband noise. That last category can be particularly entertaining to troubleshoot... in the very specific sense of “entertaining” that wireless engineers use when they have been staring at spectrum analysis for three hours! The important point is that interference doesn’t need to understand Wi-Fi to disrupt it.
