Revisiting Wi-Fi Interoperability Certification: Devil is in the Details

A vast majority of technologies blossom and wither away. Only a few of them survive the test of time. Wi-Fi seems to be one those robust technologies. It has transformed not just the way people work, but the way they communicate and play. Wi-Fi was initially designed to be a (yet another) technology to connect notebooks and computers to networks, but now it has made its way into all kinds of consumer devices – e.g., phones, PDAs, gaming consoles, cameras, DVD players, televisions. With proliferation of 802.11n, the trend is just going to increase. Hence, there is a strong need to make sure that all the Wi-Fi devices are interoperable.

Controller-less Vendor with Omnipotent Controller?

I often have the privilege of learning about new products before they are released, which allows me to get some hands-on experience and a close-up preview. Every now and again, I get a sneak peak at something special, a WLAN game changer. For a few months now, I’ve beta tested, provided detailed feedback, and worked closely with the engineering team at Aerohive in preparation for a new game changing product. Finally, the information embargo is over and I can speak freely. What a relief.

Locking down 802.1X client settings

A few months ago, I discussed the need for the Enterprise mode of WPA/WPA2 encryption in even small businesses and how outsourcing the RADIUS/802.1X server can save a great deal of time and money. Well now I'm going to show how to secure your 802.1X settings once you have a server or hosted service up and running.

Wireless Hygiene

If there’s one term that is central to wireless networking, it is this: half-duplex. I’ve heard it over and over in the past few weeks in conversations with vendors and consultants who continue to wonder why some folks still don’t understand the basics of WLAN design. As a foretaste to our real solution, here are a few broad and specific questions and answers for basic wireless hygiene that should help our friends with underperforming networks.

WLAN Website with Worthwhile Wisdom

I wanted to write a quick blog to make sure the CWNP blog reading community is made aware of another fantastic resource for WLAN professionals that just so happens to be called Wireless LAN Professionals. Keith Parsons, CWNE #3 and CWNT, launched his latest project at the beginning of this year, a website devoted to educating, informing, entertaining, and inspiring WLAN professionals, as his site’s subtitle aptly states. The free content and technical resources available there are exceptional.

Ruckus' Little Dog

The title of this article aside, I have a deep deep distaste for little dogs. They’re either yapping annoyingly or showing their teeth while snarling (that is not cute, or funny, BTW). In sum, I really do not like little dogs, and I have two words: alligator food. Sorry to little dog owners everywhere.

Wi-Forti-Fi

Way back in the days before 802.11i, Wi-Fi security was immature. WEP was the best the industry had to offer and WLAN education was in its infancy. Features like SSID hiding and MAC filtering became popular, and Wi-Fi inherited a reputation like the nervous kid in high school: insecure. As we all know, Wi-Fi uses a shared and openly accessible medium, so it has some inherent security needs, but thankfully there are more than adequate answers to the problem. In fact, many WLANs are more secure than wired LANs due to the extra diligence taken to protect them. No less, Wi-Fi security is always a hot topic and it will continue to be a hot topic… for-ever, for-ever… (ever seen The Sandlot?).

Hands-On Fluke

Most of you know by now that I spend most of my days in my home lab…writing, testing, reading, and exploring different implementations of the technology with hands-on experience. A few weeks back, I was invited by Fluke to get a little hands-on exposure to their new handheld tool, AirCheck™. Normally, when we say "hands-on," what we really mean is that you are using real equipment instead of reading a book or watching a video. This time, hands-on is quite literal; I was holding a device in my hands. :)

Subjectivity, Scrutiny, and Simpletons

Every few months, we see press from vendors pointing to tests that show why they’re the best. Best throughput, best coverage, best capacity performance, best multimedia, best whatever. Sometimes the test is done by a contracted third-party, and other times we’re graced with simple marketing tests conducted by the “best” vendor itself. Before I go any further, let me be loud and clear that this article has nothing to do with the latest two or three tests that have hit the news. It is not aimed at any specific vendor, nor is it intended to say how a product should or shouldn’t be marketed, or even that a test is or isn’t reliable. This article is here to say how I think a competitive test should be conducted by a vendor, a biased (or unbiased) third-party, or otherwise, IMHO.
