The Thing About Ventev

Having just participated in Mobility Field Day 8, I got to spend some quality time with Ventev– during which I had an epiphany of sorts. We’ll get to that in a moment.

I’ve been fortunate enough to participate in many of the Field Day events through the years. They know me out there in Silly Valley where vendors and Field Day delegates come together and discuss industry trends, new products, what works and what sucks, and so on.

Being a veteran Field Day-er, I understand the routine. Vendors present what they want the world to know, delegates ask questions and make comments to dig deeper or provide criticism (some constructive, some because often the vendors can be decoupled from the reality of what end users actually need). How effective a Field Day is depends on (in my opinion) how effective the vendors are at following the guidance given to them for their presentations by Field Day management, and the quality of the delegate’s questions and comments. There are human beings involved on both sides of the table, and sometimes one side or the other just makes a given presentation laborious. Maybe boring content is offered a mile wide and an inch deep, or perhaps a given delegate just cannot shut up as they enjoy the sound of their own voice as they redesign the vendor’s product for them in real time. Again, the human factor.

One prevailing theme from the vendor side is this: WE THINK THIS FEATURE OR THINGY IS TRULY INNOVATIVE AND SO WE WILL NOW TRY TO CONVINCE YOU DELEGATES AND THE FOLKS AT HOME SO YOU WILL PAY US LOTS OF MONEY FOR THE HARDWARE AND A SHITLOAD OF LICENSES BUT YOU MAY NOT IMMEDIATELY SEE THE VALUE SO WE GOTTA WALK YOU THROUGH IT WHILE WE HOPE YOU DON’T ASK TOO MANY QUESTIONS THAT COULD CUT INTO OUR STORY AND HENCE OUR BOTTOM LINE.

Nothing new here.

Let’s get back to Ventev, shall we? I promised you an epiphany.

So I’m listening to their Mobility Field Day 8 presentations about specialty enclosures, solar powered network “stations” (my word, not theirs) and antennas when a tidal wave of realization came over me. While network equipment vendors work hard to convince you that their often murky magic is worth the constantly elevating costs for what I often feel ought to be largely commoditized by now, Ventev sells fact. Ventev sells tangible reality. Ventev sells physics.

Whether it’s their Venvolt battery packs for survey work and temporary power needs or providing solutions for wireless access points to function out in the middle of Frozen Friggin Nowhere, Ventev doesn’t need to convince anyone of anything. When they talk about specialty antennas, their situational benefits are obvious and the physics of it all is instantaneously provable.

The Ventev narrative isn’t one of trying to out-AI or out-dashboard the other guy. They just make wireless environments better (or in some cases, even POSSIBLE). The Ventev story is end-to-end real, with no hype to sort through. No hyper-granular, squeeze-you-until-it-hurts-then-do-it-again-in-three-years-because-we-got-your-wallet–by-the-nuts-now licensing bullshit to hold your nose and pay for.

That is pretty sweet. And all too rare these days.

I suggest you get to know Ventev. Their presentations from Mobility Field Day 8 and earlier events are all found here.

Another Example of How Important Wire is to Wireless

A house built on a shaky foundation cannot endure. And a WLAN built on a shaky wiring foundation likewise cannot endure, I tellya. My friends, is your foundation shaky? Is it? CHECK YOUR FOUNDATION NOW. (I happen to sell foundation-strengthening herbal supplements on the side, if you need that sort of thing…)

I’ve long been a proponent of recognizing installed UTP as a vital component in the networking ecosystem. Too many people take Layer 1 for granted, and forgivable sins of of our 10 Mbps and Fast Ethernet pasts won’t fly in a Gig world. Toolmakers like Fluke Networks sell cable certification testers that take the guesswork out of whether a given cable run can be relied on to perform as expected. Don’t use one of these testers at time of cable installation, and you are only assuming you have a good station cable.

I just had an interesting situation come up that I helped a very skilled field tech with. He was working in several different small buildings, each serviced by a Cisco Catalyst Switch and a handful of 3802 802.11ac access points. The switches and cable had been in place for years, and the APs for many months, all with no issues whatsoever.

Then, we changed out the old 3560X switches for shiny new 3650s (curse you Cisco for your bizarre fascination with part numbers so close together), and suddenly some APs weren’t working any more. Between us, we checked all switch settings, POST reports, CDP tables, logs, etc- everything you can dream up on the switch. We put the APs that weren’t working back on the old switches, and they came right up. Hmmm… thoughts turned to PoE/code bugs, but then I went a-Googlin’ before consulting TAC.

I found this document that put me on the path to righteousness. Though we weren’t having “PoE Imax Errors”, a couple of nuggets jumped out at me about our new switches.

Holy guacamole- We got us a situation! But wait… THERE’S MORE!

Shazam! Which, of course, translates in Esperanto to “maybe your cable is actually kind of iffy, and all the CDP stuff that happens at the milliwatt level before PoE gets delivered worked OK with your old switch but not with the new one that has the enhanced PoE controller”.

If you don’t know that the newer switch does PoE differently, you might wrongly assume that your cabling is “good” because the APs worked on it when those APs used the old switches connected to that wiring. By now, you can probably guess where I’m headed…

Our tech tested the cabling on the new-switch-problem APs and in each case found that they needed help to work with the new switch. He re-terminated and tested each, with the APs then coming up with no issues. I have no doubt that this cable was certified 10-12 years ago, but in that time a lot can happen to either end of those cables depending on the environments where they are used.

Live and learn!
