CWISA: When the IT and OT Worlds Conjoin

CWNP Training Certification – CWISA: Bringing the Worlds of Wireless and Internet of Things Together!

A Certified Wireless IoT Solutions Administrator (CWISA) certification and training class has been introduced into CWNP’s portfolio. It is part of a parallel track to CWNP’s wireless training certification suite. This track focuses on IoT from the wireless perspective, and vice versa, instigating the conjoining of the worlds of IT and OT.

This first class in the parallel track is CWISA, Certified Wireless IoT Solutions Administrator, an associate-level training class aimed at bridging the gap between the worlds of wireless and Internet of Things. It investigates how wireless works, from an IoT perspective, and is an excellent introduction to IoT for the wireless engineer.

This class introduces the student to IoT and is, effectively, a CWNA-level class for people who want to learn more about IoT technologies. Conversely, it is a class about how wireless works from the perspective of an IoT/OT engineer. It is a comprehensive introduction into the world of IoT and discusses what a wireless engineer needs to operate it.

There is a difference between IT (Information Technology) engineers and OT (Operations Technology) engineers in their spheres of work, the sorts of day-to-day requirements that are asked of them, and the kinds of solutions that might be applicable to their problems. The simplest explanation is that OT deals with industrial machines (sensors, monitors, etc.) while IT, essentially, focuses on the transmission of information.

What is this training about?

In this class, students will be exposed to a number of vital aspects of IoT technology as it relates to wireless. The student will learn about the history of wireless, regulatory organizations, industry standards, and the standards lifecycle.

The class discusses vertical market considerations, along with system requirements and potential constraints. It looks at the technicalities of wave characteristics, modulation techniques, and the use and capabilities of carrier waves (including light and sound).

It also investigates the features and capabilities of various solutions, such as cellular networks, sensor networks, and IoT networks.

It is necessary to discuss various troubleshooting techniques and, of course, security features and methodolgies are examined. Additionally, this class considers programming, scripting, and automation (APIs, etc.).

So, as you can see, the class provides a good, solid, overall foundation of the way the two worlds are already beginning to combine.

Who should attend?

CWNP’s CWNA training and certification is aimed at the IT world, while CWISA is targeted at the OT world. The ideal candidate for this class would be anyone in IT or OT that wants to learn about the “other” world.

As technology continues to become increasingly integrated, we will find that the boundaries between these currently separate worlds will increasingly blur. The time is fast approaching where engineers will need to understand, and be proficient in, both IT and OT.

If you are an IT engineer wanting to learn about IoT, or if you are an OT engineer wanting to learn about wireless, this training makes for a solid foundation and a great start!

Every new Wi-Fi generation arrives with a wave of excitement: faster speeds; lower latency; more efficient use of the spectrum; and better handling of dense environments. Wi-Fi 7 is no exception. It brings some genuinely impressive technological advances but, unfortunately, it also brings a familiar myth: "If we upgrade to Wi-Fi 7, all of our wireless problems will disappear." If only wireless engineering were that simple. Wi-Fi 7 is an outstanding technology, but it isn't a magic wand. Poor design, interference, bad client behavior, and unrealistic expectations don't suddenly vanish because the APs have a shiny new logo on the box. Let's bust another myth...

Few phrases trigger a knowing smile from experienced Wi-Fi engineers quite like this one, "It's the client's fault." Someone's video call drops while walking through the office or a warehouse scanner pauses between aisles, voice handsets crackle as users move from one floor to another... then, almost immediately, someone points at the device and confidently declares, "Well... clients decide when to roam." Technically, they're correct. But, practically, that's only part of the story. Roaming is one of the most fascinating aspects of Wi-Fi because it isn't controlled by a single device or a single setting. It's a partnership between the client, the infrastructure, and the RF environment. When that partnership breaks down, blaming one side rarely tells the whole story. Let's bust another myth... Yes, Clients Make the Decision Let's start with the important truth: in almost every Wi-Fi deployment, the client device ultimately decides when to leave one AP and join another. Laptops, smartphones, tablets, barcode scanners, medical devices, and countless IoT products all use their own roaming algorithms. Some roam aggressively whereas some cling to their current AP for far too long. Others seem convinced that losing the connection entirely is preferable to switching. Every Wi-Fi engineer has encountered at least one stubborn client that appears almost “emotionally attached” to a particular AP. :) Client behavior matters, but that's not where the story ends.

Every Wi-Fi engineer has heard some version of it, "Can't we just install the access points where the old ones were?" Or perhaps, "The floorplan looks straightforward. Let's save some time and skip the survey." Occasionally, someone even says the dangerous words, "We've done hundreds of these buildings. They're all basically the same." That's usually the point where experienced wireless engineers quietly smile, knowing that the building is about to teach everyone a valuable lesson because: buildings don't read design guides, concrete doesn't care about your deployment schedule, metal doesn't respect your project budget, and radio waves have never once agreed to cooperate, simply because everyone wanted them to. Let's talk about why a site survey isn't an optional luxury... it's one of the most valuable engineering tools available. Every Building Is Different At first glance, two office buildings may appear identical: same square footage, same number of floors, similar room layouts, yet their wireless behavior can be dramatically different: one may have reinforced concrete walls, another may contain extensive glass partitions, the warehouse may be filled with moving inventory, a hospital may have elevators, imaging equipment, and countless reflective surfaces, a manufacturing facility may contain machinery that wasn't mentioned on any floorplan, and remember: even furniture changes RF behavior! Anyone who has performed enough surveys eventually develops a healthy respect for one simple fact: the building always gets a vote, too!
