Keith, as always, a great read.

I have learnt many things from your blogs/podcast. Not just in the world of 802.11 but in my day to day routines.

Keep them coming.

Keith, I know you like the concept of eye PA. Maybe you can eleborate on this topic in combination with that tool?

Re: 802.11 Quick Review

Great addition. Though I've seen Retry Transmissions as low as 5% and users complain, and as high as 80% without any complaints at all. It all depends on what user expectations are. (and the app that is running) I agree that 10% Retries is a good threshold to make you stop and find out what is causing it.

Thanks for your comment.

Keith: thank you for sharing! I also use %retransmission < 10 as a ' rule of thumb' This complies with user experiences : they start complaining if 20 or higher is reached.

I'm curious what you see/don't see in Trapeze (now Juniper) as compared to Aruba and the other tier 1s?

I think this list is pretty accurate in reflecting the current state of wifi.

I don't think it as clear-cut as to what technologies belong where, but as to who is on what slot in the "market" is seems pretty good. Cisco and Aruba are definitely right if you're showing who is really making headway in the market.

I do think we are on the same page on most of what you said... but I've met many people who've been installing WiFi *wrong* for 10 years and think they are doing fine.

I am not anti evaluation. I just don't agree with saying someone isn't competent in their field just because they don't have a specific certification. I do agree that the purpose of the certification is to validate their competency. I think we are arguing two sides of the same coin. I am not saying certifications are bad or that people should not attain them. In fact for someone just starting out in technology certifications are almost a must just to get their feet in the door, however for those of us that have been in the technology industry for 10+ years already certifications generally aren't as important other than for the marketability of having the certifications.

Norm,

I'm going to have to agree to disagree. I don't think anyone with the knowledge that's tested in the CWNA exam would have any problem actually taking the exam. NOT taking the exam doesn't prove anything.

Why are you anti evaluation?

We all get evaluated all the time - the CWNA level of knowledge is a bare minimum in our industry. Nothing wrong with proving the level of knowledge.

I wish there was a way as well to prove skills...

Re: WLAN Professionals need to be a Three-Legged Stool

Norm Mahoney — Wed, 08 Feb 2012 12:34:57 -0000

I can agree with that as I have seen the same. I have also seen those that just cram for an exam, but also are also missing a fundamental knowledge base as they are not truly "learning" the material. One thing we can agree on for sure is that experience, knowledge, and abilities are the best combination. I am just saying my view is that someone can have that combination without a bunch of framed papers on the wall.

Re: WLAN Professionals need to be a Three-Legged Stool

Keith R. Parsons — Wed, 08 Feb 2012 11:37:50 -0000

Norm,
I've seen lots of folks who *say* they have the knowledge, but they just don't want to "waste their time taking the exam" - but then find out they are missing some fundamental knowledge and observe they are doing things wrong or at least very inefficient. Certifications don't 'prove' abilities, only knowledge.

The best combination is experience, abilities, and knowledge all together!

Re: WLAN Professionals need to be a Three-Legged Stool

To clarify my post was mainly referring to your last paragraph about a minimum cert.

Re: WLAN Professionals need to be a Three-Legged Stool

Norm Mahoney — Wed, 08 Feb 2012 11:28:42 -0000

What about the ones that have the knowledge and experience but don't have the spare time or money to take the exams to prove to everyone else their abilities. This is the problem I have with certifications from A+ to CCNA to CWNP. To me these are nothing more than a bragging rights device. I would rather spend my time and money to learn and work in the real world.

you should merge 3com and HP and if some name missing into Tier1 than it is HP (but this is you list)
also Trapeze should be branded as juniper to reflect reality
Blusocket acquired by ADTRAN
Tropos is one of the vendor which ins`t mention at all

I've played around with their new 8100 gear in the lab a bit, and while it's got a lot of promise, it's still a version 1.x product. For example, there are currently quite a few AP config changes that require a full reboot of the AP to take affect. I'd say give it another year or two for spit and polish and working in a few differentiating features, and it could definitely be a contender.

Re: Update to WLAN Vendor Tiers

Frank Sweetser — Sat, 04 Feb 2012 10:01:37 -0000

We're a pretty happy Trapeze (now Juniper, actually) customer, with around 550 APs installed, and from my perspective it feels like a tier 1. Any particular reason you put them in tier 2? I've only played with aruba a bit, and haven't touched Cisco gear since it was airespace, but they feel on the same par to me.

Nice blog, I am very impressed on knowing that this information is being shared here and actively discussed by these commentators here. I do want to know certain updates though. !!!

Re: Update to WLAN Vendor Tiers

It's a pretty good list, I do think a couple off the Tier2 could be bumped up to T1 and others T3.

Any thoughts on Avaya?
