DevinitionsBy CWNP On 03/19/2009 - 5 Comments
I spoke to someone today who, like me, is on a quest to define everything that is Wi-Fi. She (my good friend Joanie Wexler) is on a quest to make sense of the ever-changing vendor definitions for their technology and to relate it back to a standard definition. KUDOS Joanie! Our mission here at CWNP is to help the industry learn to USE the standards-based terminology created by the IEEE and Wi-Fi Alliance. Where there is no standard terminology, we create it. Examples are 'Single Channel Architecture (SCA)' and 'Multiple Channel Architecture (MCA)'. You're welcome. ;-) My good friend Joel Barrett has picked up the CWNP torch of standardized exam terminology and has created an entire Wi-Fi dictionary. If you haven't seen it, see here:
If you want an example of why this stuff matters, here's my favorite. Meru and Extricom, the only two vendors to ever release products that use the Single Channel Architecture, call the blob that is their collective logic of controller and APs on a single channel, 1) channel spans, 2) channel stacks, 3) channel blankets, and 4) channel layers. Geez Luiz. Why? I'll tell you why: marketing terminology run amuck. :-) No offense is meant to either vendor of course. This is just my favorite example - there are many more just like it that involve other vendors.
How then can the industry at large - the users of Wi-Fi in particular - keep abreast of all of the marketing lingo, who's lying about what, and so forth? Well, I think it's going to take more than Joanie, Joel, and me...that's for sure. How about an industry user advocacy organization? Remember the Wireless LAN Association (WLANA)? The domain is still running at WLANA.org. If you wonder why, it's because we own it. After WLANA died, we just couldn't bear the thought of burying it. :-) It was a great idea after all...and maybe it'll rise again someday with a new set of purposes.
So, if you're still sitting there thinking, "Who does this guy think he is to be making up terminology!?" Someone has to. It's either that or we get a plethora of marketing terms to choose from that all mean some off-shoot of the same thing - none of which has ever been defined. I give you: Devinitions.
