One of the more popular reasons that people visit my website is to understand why too many SSIDs is an issue on a WLAN. I've written about performance degradation issues due to network overhead and subsequently released an SSID Overhead Calculator. The drawback to the tool is that it's in Microsoft Excel format. This makes it's use limited to people who have Excel and is only really available on workstations (not mobile devices) which makes it hard to use on-the-fly while in the field or in front of a customer.
Thanks to collaboration with Ryan Adzima, we are announcing the availability of the Revolution Wi-Fi SSID Overhead Calculator as an Apple iOS application today! You can download it here:

The iOS application provides the full functionality of the original tool right on your phone and tablet. You can adjust beacon data rate, beacon frame size, beacon interval, number of SSIDs, and number of APs on the channel. The circular bar displays the amount of overhead that the combinations will cause on your WLAN as well as a severity indication and recommendations to improve performance.
Here are a few screenshots:

So as we’re all busy network professionals, I’m sure you’ve ran into the problem of a work-life balance. I personally know lots of engineers that have burned out at one time, or their family life has suffered, and their kids barely know them. Now granted these are extreme case scenarios, but it could happen to […]

This week I have two major themes to discuss on the topic of security, and one interesting bit of research. Let’s start with some further thoughts on security by obscurity.
I’ve heard this at least a thousand times in my life as a network engineer, generally stated just about the time someone says, “well, we could hide this server…” Reality, of course, is far different; I still put curtains on my house even though they don’t increase the amount of time it takes a thief to break in. Whether or not we want to believe it, obscurity does play a positive role in security.
But there are two places where obscurity is a bad thing in the world of security. The first is the original reference of this common saying: algorithms and implementations. Hiding how you encrypt things doesn’t improve security; in fact, it decreases the overall security of the system. The second place? Communication between companies and security professionals about the types, frequency, and methods of attack. Imagine, for a moment, that you were commanding a unit on a battlefield. You hear the sounds of combat in the distance. Realizing a unit in your army is Continue reading
