VenVolt 2- Power to the (Survey) People

Hello wireless friends,

My name is VenVolt 2. I’m soon to be sent by the excellent folks at Ventev to assist you with your wireless site surveys in those situations where you need to power an access point. If you caught Mobility Field Day 6, then you saw Ventev Product Line Manager Chris Jufer introduce me… it’s a little daunting being shown off, but I can handle it. I was born for this role- some of you probably know my dad, VenVolt 1:

The Old Man still has his own magic, and quite the following. But we all know the drill… everything changes. If you get lucky, the change is for the better- and that’s where I come in. Here’s my profile pic, in case you missed it:

I’m sleek, I’m sexy, and I got the juice. Ventev learned a lot from my pappy, and I’m proud to be his follow-on in the product line. V1 uses Lithium Iron Phosphate batteries, but I’m LiPo, baby! V1 was also a bit of a porker at 4 1/2 pounds, but I go a svelt 2.2 pounds for you less macho types. And I’m rated at 26,400 mAh- just at the edge of legal airline carry-on. I charge in about 3 hours, and will power an AP for around 6-8 hours, depending on model. I could go on, but I’m already bragging a bit so maybe I’ll just show you some specs.

But first I gotta tell you- they are shipping me with this very cool bag!

You can already see the benefit there, I’m guessing. It’s not just a protective case for my handsome finish, it’s also an accessory at survey time when you need to attach me to something. (Think safety, says I.)

Now back to some specs and application notes from my demo reel. I think you’re gonna like what you see… Look for me around late September or early October of this year. Meanwhile, feast your eyes on this goodness:

I trust that you dig it? Of course you do. Because you’re smart and good-looking, too. Or maybe just smart, as I take a second look. But what matters is that I’m (almost) here for you, and you’re gonna want to make sure we get together for your Q4 surveys. I’ll see you then.

Hugs,

Ventev Knows- What a Difference That Antenna Makes

Have you ever designed a WLAN for a stadium? Ever taken a tour a of a top-tier professional stadium that has just had a a new wireless network installed throughout? I’ve done both, and the challenges of stadium WLAN have to be experienced before you can fully appreciate them. Regardless of what WLAN vendor you use on the radio side, you have to get the signals to where they need to be and to manage their fidelity in an environment that has great potential to devolve into an RF cesspool during events. Antennas- and their placement- are the keys to success, Daddy-o.

There are only so many places you can stick access points and antennas in a stadium environment’s fan seating areas. Depending on the venue, you might get great bleed-out/in between the bowl area and the concourses and office areas where different WLANs are likely to be found. Then there is the sheer volume of client devices, the other RF systems on and around the field, and whatever hotspot noisemakers fans and media show up with. Precision placement, alignment, and antenna patterns are the stuff of stadium wireless networks, and it’s all gotta be done in a way that protects the WLAN gear and rowdy fans from each other.

Lately, I’ve been fortunate to spend a little time on multiple occasions with Dennis Burrell of Ventev talking about antennas and his work designing them for challenging environments. Let’s have a look at one of Ventev’s specialty solutions, straight from Soldier Field (home of the NFL’s Chicago Bears):

And now a cutaway of that “handrail enclosure”:

If it’s not obvious, the advantage here is that the antennas are not below the seats or at some far-away overhead mounting location, but rather at waist-height with more clear lines of sight into the adjacent seating rows, shooting in two directions out of one enclosure. You can read more about the 275 of these units at Soldier Field here.

It’s fascinating to see the stadium challenges get answered by people like Burrell who have the talent, know-how, and empowerment to do what needs to be done. I also wrote this recently, which will lead you to many more of Ventev’s stadium projects.

Finally- let’s see what you might now about the stadium Wi-Fi market. Any idea how many large venues are “out there”? My past blog “What’s the Big Deal With Stadium Wi-Fi?” will help you to appreciate this fascinating space. And in this space, you can bet that the WLAN designers and owners appreciate Ventev’s contributions.
