Everything you wanted to know about WLAN but were too afraid to ask!
Organizations spend millions of dollars on their wireless networks, but very few understand how they really work. With Wi-Fi 6/6E and network refreshes at the height of popularity, it's now time your entire team understands how WLAN really works and why it should be monitored and secured. This extends to the home networks of your ever-growing remote worker population as well.
Topics you'll learn about:
· How Wi-Fi works
· Root cause of Wi-Fi issues
· Licensed & unlicensed bands
· Channel planning
· Types of interference
· And more!
The trouble report comes in, and you get to work figuring out where the issue is in the wireless network. And that may be why you don’t solve the problem very fast.
Join us to discuss why Wi-Fi trouble may or may not be the source of frustration, and why developing a ten-thousand-foot view is imperative when it comes to troubleshooting Wi-Fi.
We are thrilled to welcome Keith Parsons back for another webinar session. Keith, CWNE #3, is the founder of WLAN Pros and has earned over 60 networking certifications. He is considered one of the world's top authorities on all things Wi-Fi. We just completed the 10th anniversary of the Wireless LAN Professionals conferences. This year we had 11 3-day pre-conference boot camps, and 15 different 6-hour deep dives, plus over 50 presentations. Keith will share his top ten highlights of the conference and point to the online videos you might want to check out first. As well as some time for Q&A from the audience to answer your questions, and ask about what you’d like to see in future conferences.
The buzz is starting for Wi-Fi 7 now that the Wi-Fi Alliance has announced its certification program. There are lots of big numbers for marketers to bandy around, but what doesn’t change for the better when it comes to Wi-Fi 7? No one likes a party pooper, but when it comes to understanding your WLAN, truth trumps hype.
In this session we will explore the complicated landscape of Wi-Fi and its love/hate relationship with clients. Why is it so difficult to design and maintain an infrastructure that allows for lasting, reliable connectivity? How can we foster a better environment? We’ll discuss that and more with Lee Badman.
The story of how Wi-Fi came to be one of our most significant technologies is surprisingly dramatic. Coming out of the fierce techno/political battles at its birth, Wi-Fi exploded into tens of billions of devices around the globe, where today it supports over half of all internet traffic. This presentation will cover the backstory behind the Wi-Fi phenomenon and will look at what the future might bring.
