Name: Kjetil Teigen Hansen

Role/Title: Senior Network Consultant

Who are you, professionally speaking?

I am an experienced CWNE 504–certified wireless networking expert with deep expertise in Wi-Fi, RF analysis, and wireless systems across frequency bands. I work with analysis, design, optimization, and troubleshooting of wireless networks in complex and demanding environments, with a particular focus on spectrum, noise, interference, and performance.

CWNE (Certified Wireless Network Expert) is the highest level in the CWNP certification track and confirms advanced expertise in architecture, implementation, security, optimization, and troubleshooting of wireless networks. In addition, I am Cisco certified, with solid experience from enterprise environments and a vendor-agnostic approach to wireless technology.

On a day-to-day basis, I work on complex network and infrastructure projects, using Cisco and other enterprise technologies to ensure reliable solutions and satisfied customers.

My passion lies in combining deep technical insight with practical testing and tool development: from RF analysis, 5G and Wi-Fi measurements, and quality testing, to protocol debugging, AI-driven automation, and product reviews, as well as helping customers improve, optimize, and understand their wireless solutions.

I was also awarded Cisco’s Screwdriver of the Year in 2024 and have held Cisco Champion status since 2019.

What does your typical workday look like

There is rarely a completely typical day. My workday varies between customer work, analysis, troubleshooting, design, documentation, and advisory tasks. Some days are very hands-on and technical, while others are more focused on customer dialogue and collaboration with colleagues. The common denominator is always solving real problems and making wireless solutions better.

What do you like to do in your spare time?

In my spare time, I work on technical quality assurance as a hobby—I test software and products for defects, robustness, and real-world value, both for my own learning and for users worldwide. This work spans open-source projects and self-developed tools to commercial Wi-Fi access points and networking equipment, where I actively look for edge cases, performance issues, and unexpected behavior.

I also develop my own AI tools to automate tasks, analyze data, and make everyday work easier for both engineers and technically curious users. This includes everything from mobile coverage analysis for 4G and 5G, analysis tools for Cisco and Aruba environments, Wi-Fi spectrum analysis software, to integrations and helper tools for Hamina and Ekahau—with the goal of making the workday of Wi-Fi professionals both easier and more enjoyable.

On the side, I also run several technical projects and tool resources. I have a YouTube channel, a comprehensive Aaronia RTSA-Pro guide (aaronia.teigenrf.org), and an AI tools site for Hamina and other Wi-Fi tools (tools.teigenrf.org). These projects combine hobby, learning, and knowledge sharing for engineers and wireless enthusiasts around the world.

You originally come from Bluetree, which has just merged with Sicra. What are your thoughts on the merger, and what expectations do you have for the transition from Bluetree to Sicra?

I see the merger very positively. Bluetree and Sicra complement each other well, both professionally and culturally. For me, the transition is primarily about gaining access to a broader professional environment, more exciting projects, and the opportunity to collaborate with even more skilled people. I expect the combined expertise to create room for both professional growth and improved customer deliveries.

What is the most underestimated problem in Wi-Fi environments today?

A lack of understanding of RF and spectrum. Many issues appear to be “Wi-Fi problems” but are actually caused by DHCP, DNS, or other underlying network functions.

What does success mean to you professionally?

Success is when a solution actually works well in practice, not just on paper—and when the customer understands why it works. For me, success also means learning something new along the way and being able to share that knowledge with others.

What motivates you in your daily work? What do you find most rewarding to work on?

I am motivated by complex problems that require deep technical understanding. What I find most rewarding is identifying the root cause of an issue, especially when it involves RF, performance, or edge cases that are not obvious at first glance.

What are you most looking forward to going forward?

I look forward to getting to know the professional environment at Sicra better, working on new types of projects, and further developing how we use automation and analysis tools within wireless networking.

Which app or tool do you use the most in your daily work, and why?

It varies, but Wi-Fi and spectrum analysis and visualization tools are always in use. In addition, I use my own small tools and scripts to analyze data faster and identify patterns that are not always visible in standard tools.

Do you have a favorite quote?

“It depends.” – because it almost always does, especially in networking and Wi-Fi.
