Capacity Planning

Push It To The Limit! Understand Wi-Fi’s Breaking Point to Design Better WLANs

This is the fourth and final blog post in the WLAN capacity planning series. Be sure to read the first, second, and third posts.

We all want high performing WLANs. In order to do that we must push Wi-Fi to its limits! 

(Cue Scarface Theme, verse 1)…

Push it to the limit!
Walk along the perimeter edge
But don’t look up, just keep your head
And you’ll be finished

Survey to the limit!
Past the point of no bandwidth
You’ve reached the edge but still you gotta learn
How to build it

Hit the floor and double your pace
Laptop wide open like an engineer outta hell
And you crush the speed test

Going for the back of every room
Nothing gonna stop you
There’s no wall that strong
So close now, battery near the brink
So, push it!

We walk a fine line when designing wireless networks, attempting to push as many users and bandwidth through our APs as possible, ensuring adequate capacity is available to meet demand, while not overbuilding the network. But what are the limits and how do we know we’ve hit them? Or more importantly, how do we plan and design Wi-Fi networks to make sure we don’t hit these limits?

Wi-Fi Design and Capacity Planning Webinars, May 19th and 21st

Please consider attending webinars I'll be hosting on Wi-Fi design and capacity planning next week with Aruba Networks. I'll be talking about the key aspects to WLAN performance and the approach that I take to integrating coverage and capacity into a holistic design, as well as tools you can use to monitor WLAN performance after deployment to maintain a high-performing network and plan for growth.

These won't be traditional marketing webinars. If you're like me, you get invited to (and avoid) many webinars because they are too sales oriented and lack relevant engineering content. This isn't that. The goal of these webinars is to provide practical, real-world concepts and methods to help you design better Wi-Fi networks. Everyone deserves better Wi-Fi, right?

U.S. Webinar - May 19th at 11am PDT / 2pm EDT

EMEA Webinar - May 21st at 15:00 GMT

Understanding 802.11 Medium Contention

In this post, I dive deep into 802.11 medium contention to understand how it works as a precursor to the final blog post in this series where I’ll detail the two main sources of medium contention, identify Wi-Fi's breaking point (that'll be fun, stay tuned) and how this affects proper WLAN design in order to optimize wireless networks to prevent medium contention from killing your WLAN performance.
