Clear To Send: Wireless Network Engineering: Recent Episodes
Rowell Dionicio and François Vergès
Clear To Send is a podcast about wireless engineering where we educate you on WiFi technology, talk about design tips, troubleshooting, interviews, and the tools.
We’re trying out something new in this episode. We’re asking each other questions on “Would you rather” to get insight into how we would do Wi-Fi given we had two options.
What you’ll find is that we don’t always agree on the same things. And that’s okay.
More importantly, is diving into the reasons why. If you find that there’s a topic you’d like to learn more about, please let us know in the comments below.

Let me walk through what a day in the life of a WLAN Engineer looks like in Higher Education and in a consulting role.
Both are different but they share similar characteristics.
In Higher Education, the day can start with tickets or with a new Wi-Fi design. We have the flexibility here to design our day. But there’s no doubt it can be filled with unnecessary meetings.
For a WLAN Engineer in a consulting role, those meetings can be absolutely necessary in order to have a positive outcome in an engagement.
I’ve been fortunate to hold hats in both roles and I enjoy doing both.
If you’d like to share what your day looks like as a WLAN Engineer, please leave a comment down below.

In this episode, we’re diving into some Python and APIs to visualize data within Grafana. This episode is part of Rowell’s automation journey. He has been learning Python with his daughter.
For Rowell, this is just the beginning as he starts integrating Grafana with InfluxDB and Telegraf. A lot more has to be learned in addition to Python and API.
Within the video, we look into the Mist API and see how Rowell was able to develop a script to pull specific information that could be part of a dashboard within Grafana.

Managing Wi-Fi at high-density events is a completely different game than running a typical enterprise network — it’s crowded, fast-moving, and unforgiving. In this episode, Francois and I break down what it really takes to deliver reliable event Wi-Fi, starting with planning and preparation. You have to decide early if you’re relying on the venue’s existing network or building your own (which can mean deploying hundreds of APs in just a few days), and even if it’s the same venue, the layout changes every time. What matters most is understanding how people move and behave — like when a huge crowd hits the security area and everyone downloads the conference app at once — and planning your capacity around those predictable bottlenecks so you’re not constantly reacting under pressure.
We also talk about how monitoring event Wi-Fi needs a different mindset and a tighter feedback loop. Instead of waiting for tickets to roll in, you need to watch live performance signals like channel utilization, client counts per radio, and clients per SSID, because those trends tell you what’s about to break before it breaks. For visibility, we’ve leaned on custom scripts feeding Grafana dashboards from controller or cloud APIs, and when you’re on the floor you need tools that move with you — like Ekahau Analyzer with a Sidekick for raw channel utilization, or WN Pi Go for quickly spotting the APs under the most stress. And if you’re running both 5 GHz and 6 GHz, don’t forget to test with older 5 GHz-only devices, because modern clients will jump to 6 GHz and hide a bad 5 GHz experience.
Finally, we get into interference and troubleshooting — because at events you’re dealing with both Wi-Fi and non-Wi-Fi problems constantly. Spectrum sweeps before the event can uncover noise sources like audio/video equipment, but one of the biggest offenders is wireless camera gear used for live streaming that blasts video across Wi-Fi channels and can even shift frequencies automatically. Add in rogue exhibitor APs running full power with 80 MHz channels and you’ve got a recipe for chaos unless you’re actively managing spectrum and enforcing RF rules. The big lesson: the more scenarios you plan for ahead of time — including staging backup APs you can activate instantly or deploying an autonomous AP on a reserved channel for a high-demand demo — the faster you can react in real time and keep the event experience solid.

This video, a deep dive on frame analysis, covers the essentials of capturing Wi-Fi frames and analyzing them using Wireshark. These skills discussed are useful for troubleshooting and for those studying for their CWAP certification.
Capturing Wi-Fi FramesTo properly capture 802.11 frames, a Wi-Fi network interface card (NIC) must be set to monitor mode, as simply running Wireshark will only capture data at Layer 3 and above.
This video, a deep dive on frame analysis, covers the essentials of capturing Wi-Fi frames and analyzing them using Wireshark. The speakers note that the skills discussed are useful for troubleshooting and for those studying for their CWAP certification.
Capturing Wi-Fi FramesTo properly capture 802.11 frames, a Wi-Fi network interface card (NIC) must be set to monitor mode, as simply running Wireshark will only capture data at Layer 3 and above.
Capture Tools and Tips:
- macOS: Users can employ the AirTool software to put their card into monitor mode and perform a packet capture on one channel.
- Unix-based systems are generally easier to use for capture due to more monitor-mode-friendly drivers.
- Dedicated Tools: Dedicated tools like the Sidekick (which uses Unix and has multiple Wi-Fi NICs for multi-channel capture) and the WLAN Go (a lightweight tool that can be attached to a phone and supports Wi-Fi 7 frame captures) are also recommended.
- Placement: The capture device should be closer to the client (for client-side troubleshooting) or the AP (for AP-side troubleshooting).
- AP Capture: Some systems allow packet captures to be performed directly on the access points, which can track a client’s MAC address across different APs and channels, or even capture traffic on the wired port.
- Best Practice: The speakers recommend capturing all traffic first and then filtering later in Wireshark to ensure nothing is missed.
Analyzing Frames with WiresharkAnalysis begins by importing the 802.11 frames into Wireshark. Key features and tips for navigating potentially overwhelming files (containing thousands or millions of frames) include:
1. Filters and Profiles
- Display Filters: Filters are essential for cutting through the noise. Wi-Fi filters typically begin with
wlan.. - Right-Click Filtering: A fast way to create a filter is to right-click on a specific field in a frame and select “Apply as Filter” or “Prepare as Filter”.
wlan.addrFilter: To see both uplink and downlink traffic for a specific device, modify a filter based on the transmit address (wlan.ta) to usewlan.addrinstead.- Profiles: Users can create or download profiles (like the WLAN Pros Master or MetaGeek profile) to store a set of default Wi-Fi filters and apply color-coding to different frame types, such as management or data frames.
2. Visual Aids and Customization
- Packet Diagram: This feature (found in Wireshark’s preferences under the layout view) displays a diagram of the frame’s header fields, bit-by-bit, which is helpful for studying different protocols.
- Column Customization: Columns can be added or adjusted by right-clicking on any column.
- Aliases: For devices not using randomized MAC addresses, users can create aliases (names) for MAC addresses in the
ethersfile to make the frame list more readable.
3. I/O Graphs (Input/Output Graphs)
- I/O graphs are an underutilized feature for visualizing events and trends over time.
- Roaming Analysis: They are particularly useful for analyzing roaming by graphing events like probe requests and reassociations.
- Signal Strength: I/O graphs can also track Layer 1 data like RSSI values over time, allowing analysts to correlate signal strength drops with client behavior like when the client starts probing.
- Other Applications: They can show the proportion of transmitted frames versus retry frames, or be used to visualize rate shifting.
4. Practice and Export
- Learning: The best way to learn is to study normal traffic first (e.g., active/passive discovery, authentication, association) to become more efficient at spotting anomalies later.
- Exporting: For large captures, users can mark frames of interest (Command M on a Mac) and then export only the marked packets to a new PCAP file, making the analysis of those specific frames faster and easier.

The video is an episode of the Clear To Send podcast, hosted by Rowell Dionicio and Francois, where they discuss spectrum analysis tools.
Summary of Spectrum Analysis Discussion:
- What is Spectrum Analysis? A spectrum analyzer measures activities on the RF layer (Layer 1), specifically for the 2.4 GHz, 5 GHz, and 6 GHz frequencies that Wi-Fi uses. It measures the signals and their amplitude, showing which frequencies or channels are busy and how often they are used (duty cycle or channel utilization).
- Purpose: Spectrum analysis is used by Wi-Fi engineers for tasks like Wi-Fi validation surveys and troubleshooting. The goal is to see if everything is taking place normally, understand what Wi-Fi traffic looks like, and spot non-Wi-Fi traffic (interference) that could be impacting Wi-Fi.
- On-Site Requirement: Spectrum analysis usually requires being on-site to find the source of interference in the real world.
- Tools: For accurate analysis, a dedicated spectrum chipset is needed, as general Wi-Fi network interface cards (NICs) often only estimate channel utilization rather than provide an accurate measurement. The dedicated tools, such as the Ekahau Sidekick, offer higher resolution and faster scanning.
- Visualizing the Spectrum (using the Ekahau Sidekick):
- Density View: Shown at the top, it plots frequency (x-axis, Wi-Fi channels) against amplitude (y-axis, in dBm). Colors in the density view indicate how busy the channels are (e.g., orange is 50% busy, red is 100% busy).
- Waterfall View: Records measurements over time, showing the evolution of the spectrum. Colors in this view indicate the strength of the signal, with red meaning the analyzer is close to the source. This view is good for identifying if a device is always transmitting on the same channel or hopping around, and when a device is transmitting.
- Signal Shapes: An important piece of information is the shape of the signals, as each device generates signals with a specific shape. The speaker recommends learning to recognize these shapes, such as the Orthogonal Frequency-Division Multiplexing (OFDM) signature of Wi-Fi.
- Wi-Fi Traffic Example (5 GHz): When a speed test was initiated on an iPad, the spectrum analyzer showed a strong, busy 80 MHz wide channel. The channel utilization rose to the 90s temporarily. The speed test also clearly showed the OFDM shape of Wi-Fi, including a characteristic dip in the middle.
- Non-Wi-Fi Interference Examples:
- Factory Lights: An interference case in a factory showed a jagged mountain shape of activity across the entire UNII-3 band (Channels 149, 153, 157, 161, 165) that was 100% busy. This was caused by motion detection sensors likely associated with the lights. The solution was to exclude those channels from the Wi-Fi channel plan.
- Video Transmitters (6 GHz): Interference that looked like busy Wi-Fi traffic (having the OFDM shape) was detected in the 6 GHz band. This was from video transmitters connected to a cameraman’s camera, sending a live video feed, and it was using the channel nearly 100% of the time.
- Drone: A drone, when turned on, generated a steady 20 MHz wide, OFDM signal on a 5 GHz channel, sitting on top of the host’s 80 MHz Wi-Fi channel and utilizing 50% of the channel.
- DJI Mic (2.4 GHz): The microphone system was seen hopping across four narrow channels (2-3 MHz wide) in a pattern.
- Microwave: A microwave oven can show a lot of spectrum activity, which could indicate a need for replacement if the shielding is not adequate.

In this episode of Clear to Send, the team shares their forward-looking predictions for 2026, grounded in real-world deployments and patterns they’re seeing across the Wi-Fi industry. From spectrum usage to client behavior, the conversation frames what engineers and IT leaders should be preparing for as Wi-Fi continues to evolve globally.
A major theme is the acceleration of 6 GHz adoption, especially in North America, with expectations that standard-power 6 GHz devices and AFC-enabled designs will become more common. The hosts predict a tipping point where 6 GHz client connections rival—and surpass—5 GHz, naturally improving network load balancing. They also discuss regional differences, noting uncertainty around upper 6 GHz availability in Europe, alongside a broader push toward WPA3 migrations and the operational challenges posed by legacy and IoT devices.
The episode rounds out with predictions on technology and market shifts: deeper learnings from early Wi-Fi 7 deployments, more practical and embedded uses of AI in engineering workflows, and increased adoption of Ultra-Wideband for precise location services without overlay networks. On the vendor side, the hosts speculate that a more agile challenger could emerge to compete with incumbents like HPE and Cisco, while device trends point toward broader adoption of Apple’s in-house wireless silicon across the ecosystem—making 2026 a year of refinement, validation, and meaningful change rather than pure hype.

The wireless networking industry is experiencing a significant shift toward cloud-managed architectures. This transition is driven by vendors seeking to deliver advanced capabilities like AI-powered analytics and comprehensive APIs that traditional controllers struggle to support. Additionally, the subscription model provides vendors with predictable recurring revenue compared to one-time hardware sales.
However, this evolution brings several challenges. Many organizations face regulatory compliance requirements that restrict cloud connectivity, while others must navigate significant infrastructure redesigns. Technical considerations include gateway functionality for services like OpenRoaming and ensuring network survivability during internet outages.
Financial implications are substantial as organizations shift from capital expenditures to operational costs. This budget restructuring often raises concerns about long-term expenses and vendor lock-in—what happens to network functionality if subscriptions lapse?
In response, hybrid solutions are emerging. Products like Mist Edge, Meraki MG, and Aruba EdgeConnect provide local processing capabilities while maintaining cloud management benefits, addressing reliability and compliance requirements.
Perhaps most significant is the cultural transformation required of network professionals. Engineers accustomed to command-line interfaces must adapt to API-driven management, developing programming skills and embracing automation. This represents a fundamental shift in how wireless networks are designed, deployed, and managed.

Designing Wi-Fi networks for high-density lecture halls has unique challenges due to the concentration of devices in a confined space. Designs must account for both capacity and coverage, implementing access point placement strategies that minimize co-channel interference while maximizing signal quality.
Beyond the technical aspects, successful lecture hall Wi-Fi implementations must consider actual usage patterns and building requirements.
Continuous performance monitoring through heat maps, client connection statistics, and application performance metrics should be considered. It's essential to design with future growth in mind, planning for increased device density as students bring multiple connected devices to class.
The ultimate goal is creating a seamless wireless experience that supports interactive learning technologies while remaining invisible to users, allowing educators and students to focus on the learning experience rather than connectivity issues.

In this episode, we talk about the latest news around the Wireless industry.
An article from RCR Wireless by James Blackman indicates that T-Mobile is pulling back on CBRS support for neutral-host 5G. That leaves only AT&T in the same stance it has had and Verizon Wireless maintaining their viewpoint. T-Mobile will continue to offer selective support for CBRS deployments. How does this impact neutral host for vendor partners? It limits the use cases of private 5G to equipment that can take advantage of the lower frequencies and network slicing.
Cisco has announced they are bringing back the dedicated Wireless track certifications. In 2026, you will not see any wireless concepts in ENCOR. Instead, there will be new CCNP wireless certification exams: Implementing and Operating Cisco Wireless Core Technologies (350-101 WLCOR) with two concentration exams — Designing Cisco Wireless Networks (300-110 WLSD) and Implementing Cisco Wireless Advanced Solutions (WLSI 300-120)
Looking to add a tool to your wireless kit? Check out the WLAN Pi Go. It’s a portable Wi-Fi analysis tool you can take everywhere with you. Connects to your mobile phone or your laptop. It has an Intel BE200 Wi-Fi adapter supporting Wi-Fi 7 and the 6 GHz band. We’ll get a better look at it at WLPC Prague.
Speaking of, Rowell will be attending WLPC Prague and presenting. Find Rowell at the conference and ask for a sticker and a pin!
Ubiquiti shared their latest 2025 Q4 earnings report and the revenue is staggering! How is Ubiquiti not in the Gartner Magic Quadrant? We gave our thoughts and opinions of the direction Ubiquiti is taking.
HPE finally closes the acquisition of Juniper Networks. But we won’t see any big changes just yet. We predict those big changes will arrive in the coming years. How long will that honeymoon period last and what kind of changes will we expect from here on out?

In this episode, we dive into Arista Networks’ bold moves in the campus networking space, where they’re seeing a wave of customers migrating from legacy vendors due to lack of visibility, complex management, and poor support. Arista’s differentiators—like a tri-band multifunction radio, client simulation for network assurance, integrated WIPS, and hitless AP upgrades—are resonating with enterprises looking for more simplicity and intelligence in their networks. The team also showcased their latest on Wi-Fi 7, including live demos of enhanced MLO performance and “digital twin” style experience monitoring enabled by a multifunction radio that can simulate clients in real time.
We also break down Arista’s architectural innovations in large-scale Layer 2 mobility with VESPA (Virtual ES with Path Aliasing) and MRO (MAC Rewrite Offload). These technologies eliminate legacy challenges like unknown destination flooding and ARP storms by combining standards-based EVPN with smarter AP behavior—making it possible to scale Layer 2 mobility across massive campus environments without disrupting applications. For security-conscious organizations, Arista now offers CV AGNI on-prem, a high-scale, containerized NAC solution that keeps data 100% on-site. With innovations in user segmentation using UPSK and a future-focused view on simplified mobility, Arista is positioning itself as a serious challenger in the enterprise campus space.

In this episode, we unpack the latest from Cisco’s wireless portfolio as they move toward a unified platform—no longer “Cisco vs. Meraki,” but a single product line with common licensing and support. Cisco’s Wi-Fi 7 access points (CW9172, CW9176I/D1, CW9178) offer future-ready performance while supporting legacy 2.4 and 5 GHz devices. We cover client readiness, advanced Wi-Fi 7 features like multi-link operation (MLO), and new security standards (GCMP-256, WPA3-SAE). But while the controller offers unmatched configuration flexibility, it demands deep operator expertise. Design complexity increases as organizations juggle cipher compatibility, roaming reliability, and client capability gaps.
We also discuss the new Campus Gateway solution designed to give Meraki customers seamless roaming across large campuses without redesigning their WLAN architecture. While technically impressive—leveraging QUIC for the control plane, VXLAN for tunneling, and active-active high availability—our take is that the solution arrives too late to reclaim customers who’ve already moved on. Finally, Cisco brings assurance intelligence enhancements, offering deeper user experience insights and more actionable troubleshooting tools—though many of these features feel like Cisco playing catch-up. Tune in for real-world perspectives on what’s exciting, what’s complex, and what’s still missing in Cisco’s wireless evolution.

Live demos are awesome to see. And when executed very well it is impressive. Arista Networks came to Mobility Field Day 11 ready to wow the delegates.
With a Wi-Fi 7 access point in the room and a Google Pixel phone, they were able to show how MLO works in Wi-Fi 7.
From their dashboard, it showed how the phone was associated to both 5 GHz and 6 GHz channel on a single access point.
In addition to MLO, they also showed a demo of how puncturing would work. An interference source was synthetically created via software just to show one channel being removed but Wi-Fi still operating well.
Check out the MFD11 video and be sure to look at the pcap Rowell was able to capture which shows the MLO information elements.

https://youtu.be/nCLoqCq-1CMRowell was fortunate to be a delegate for Mobility Field Day (MFD) 11 which was located in Santa Clara, CA. Juniper Networks was the first presenter at MFD11 and just like in previous MFD events, there were many announcements and new features coming to the Mist dashboard.
A lot of the discussion does revolve around Marvis and the AI capability. Marvis Minis weren’t announce too long ago for access points and now they will be extended to providing testing for applications such as Zoom and Teams. With this comes new Application SLEs.
Providing insight into the user experience is a nice way to measure the impact of poor application performance. AI is used to take Zoom data merged with network data from wired, wireless, SD-WAN, etc to build models that can predict latency with up to +/- 9ms of accuracy.
When it comes to user experience, I would like to gather data closer to the device being used. That’s where the Marvis Client Agent comes into play. It will be able to provide more information to feed on layer 2 information and display within Client Insights on the dashboard.
Troubleshooting Wi-Fi is challenging. But the Mist dashboard is helping to bridge the gap by providing information that occurred in the past with Dynamic Spectrum Capture. We’ve known that intermittent issues have been difficult to track, especially RF interference.
And when you have to troubleshoot remote sites, it’s not easy to fly someone onsite to troubleshoot, especially when travel costs are involved. Juniper Networks brought Jussi Kiviniemi as a guest to display live troubleshooting and analysis using Hamina. It utilizes the Mist API to pull in RF data to get a live heatmap view on a floor plan within Hamina.
Like I said, Juniper Networks announced a lot of new features. Watch the full video for yourself!

Rowell and Jussi discussed the use of 3D modeling for Wi-Fi design and validation using Hamina. Jussi demonstrated the tool they use, showing how it can predict signal behavior in a warehouse environment.
They also discussed the importance of 3D modeling for validating project details like shelf heights and the construction of walls.
There’s immense value of this tool for collaboration with non-Wi-Fi professionals.
3D modeling is useful in a stadium environment using slopes and raised floors. Jussi explained how the simplicity Hamina allows for complex designs. The importance of the material of the raised floor was also highlighted.
Jussi goes into how Hamina will be used to perform a validation survey. At Hamina, they developed a mobile app and hardware for this purpose, which stores data locally and uploads it to the cloud when an internet connection is available. The device, which can host four Wi-Fi 6E adapters and includes a USB-C connector for data, supports optional spectrum analysis. Jussi confirmed the device’s battery life is not affected by its size and it can last half a day before needing a charge.
Going into the various survey methods, specifically Point Survey, Line Survey, and Continuous Survey. Jussi explained that Point Survey is a simple method that collects data intermittently, whereas Line Survey collects data continuously but provides a bit more relaxation time between clicks.
As far as functionality goes, Jussi confirmed that the app continuously saves measurements to prevent data loss and can detect the vendor of the Access Point automatically. The app’s analysis features include primary and secondary coverage, channel interference, and the ability to view data for specific frequencies or SSIDs.

Rowell and François discussed their experiences with deploying OWE and WPA3 on a higher education Wi-Fi network. Rowell noted that the adoption has been slow due to device compatibility issues, particularly in higher education where many devices are personal and outside of their control. They opted for a slow rollout strategy to monitor and gather information, emphasizing the importance of planning. Rowell admitted that their strategy was a hope for the best, as they couldn’t be certain about the device updates.
This episode is sponsored by WiFi Scanner.
Different SSIDs are used for OWE and eduroam with WPA3. Device compatibility was tested with the new mode and addressed potential user concerns. There was also a consideration for the need for educating the team about the new configuration and verification process.
Rowell discussed the method he used to gather statistics and troubleshoot issues related to the use of OWE. He mentioned that he rolled out the change silently to a few buildings and decided not to notify the end users about the change to avoid an increase in tickets. Rowell also explained that they transitioned to Mist and chose to roll out the OWE change per site, limiting it to specific buildings.
What about Wi-Fi 6E and WPA3 deployment? Rowell explained that they initially had issues with devices supporting 6 GHz, leading to connectivity problems. The transition to WPA3 was largely successful, with no complaints from users, and they are now using 8 buildings with OWE transition mode and WPA3-Enterprise only. The discussion concluded with a brief mention of an issue with meeting room devices connecting to Wi-Fi.

In this episode, we are having the pleasure to welcome Greg Ennis on the show. Greg is the author of the book called Beyond Everywhere, How Wi-Fi Became the World’s Most Beloved Technology.
Greg is one of the founders of the Wi-Fi protocol. He has worked with organizations such as the IEEE and the Wi-Fi Alliance to create and democratize this technology. Having had the privilege of witnessing the creation and success of Wi-Fi, he decided to write a book about its history, using his own story as a foundation.
Here is how the author describe what the book is about on his website:
Billions of people rely upon Wi-Fi every day. With 18 billion Wi-Fi devices around the globe, and with 4 billion more sold every year, it supports over half of all internet traffic. But we all simply take it for granted — our ever-present companion, so prevalent as to be virtually “beyond everywhere”, working exactly the same in Cairo, Beijing, and Tierra del Fuego, in planes and cars, hotels and shops, connecting laptops, cellphones, TVs, cameras, thermostats and just about everything else. How did this come to be?
Beyond Everywhere tells the entire dramatic Wi-Fi story, spanning two decades and three continents — its origins including an FBI sting operation, the intense battles among rivals as the standard was being developed, to its final explosive success all over the globe. Written by one of Wi-Fi’s key players, this is the definitive inside story of how Wi-Fi became the world’s most beloved technology.

WLPC is the Wi-Fi conference to attend. Clear To Send attended the conference in Phoenix in February 2023. It happened to be right before the SuperBowl.
This episode is sponsored by Optifi
It’s a great feeling to attend WLPC and catch up with all our peers and friends. We feel energized during and after the event.
Our favorite part of WLPC is to speak with a lot of different people because the discussions are where you learn the most. There are people from partners, vendors, trainers, etc. A wide range of people with various experiences and skillsets.
A tip for first-time attendees is to bring a suitcase with extra room. You’ll always leave the conference with some goodies, especially if you’re doing a deep dive.
Some of our favorite sessions:
- Secure Wi-Fi Migrations: A WPA3 How-To
- Wi-Fi 6E, Year Two

The CWNA is our most recommended certification and first path to becoming a Wi-Fi specialist or expert. You’ll gain an immense amount of Wi-Fi fundamentals that will lead you to become the go-to Wi-Fi person in your organization.
These are our 5 reasons why you should get your CWNA.
Get Wi-Fi FundamentalsThe CWNA provides you so much Wi-Fi fundamentals that you’ll be able to get started with any Wi-Fi project. You’ll probably look back at previous Wi-Fi installations and identify any incorrect implementation. Many network engineers lack fundamental Wi-Fi knowledge to properly configure and deploy access points.
Stand out as a network engineerWe’ve come across many network engineers who do not have enough Wi-Fi knowledge to make the correct configurations, select the right antennas, or design properly for a high performing and well optimized Wi-Fi network.
And since Wi-Fi is the most used method to access the network, a network engineer must know how Wi-Fi works!
Become specializedThe CWNA is one path to become a specialized network engineer focusing on Wi-Fi. In addition to standing out as a network engineer, people will look to your expertise for future Wi-Fi projects and troubleshooting. It can open up a lot of doors and further your career.
Improve troubleshootingA skill most often lacking is troubleshooting Wi-Fi networks. Many network engineers blindly tune Wi-Fi networks and make it worse. It’s important to understand what vendor knobs do and what kind of impact it will create on a Wi-Fi network. Having the fundamentals will lead to better troubleshooting Wi-Fi skills.
Vendor-neutral educationThe CWNA certification comes from CWNP and it is a vendor-neutral certification. We often recommended getting this Wi-Fi certification first before jumping into a vendor-specific certification. It will give you a leg up making it a little more easier to work on vendor hardware.
