At Least 18% of All Vehicles With Wi-Fi Are Integrated (Maybe)

When you read this blog, you get value. As the Chief Data Scientist for Wirednot LLC, I crunch numbers and I draw conclusions so you don’t have to. I’ll pie you up a chart so fine you’ll wonder what happened… but that’s besides the point. I’m here today to declare that minimally 18% of all vehicles on the road with a Wi-Fi signal might be equipped with in-built WLAN capabilities. And I stand behind behind that uncertain claim with conviction, I tellya.

The Methodology

Find yourself a busy two lane road, like Route 5 in Elbridge, NY.
route 5

Build yourself a business alongside that busy two-lane road, maybe something like this one. When you do the networking for that business, pay attention to what you see in the Air Marshal dashboard in it’s Meraki wireless system.


The Findings

Seeing that this fairly isolated establishment (no neighbors) “saw”over 1,000 outside SSIDs in a week, I was struck by how many were OBVIOUSLY automobiles and likely built-in. I went through, and counted applied an advanced algorithm to arrive at around 180 of these being safe bets as automobile-mounted Wi-Fi.

That’s 18%, where I come from, baby.

Now the Fudge Factor

In reality, at least twice of the guaranteed-auto SSIDs looked like they were “likely” car-mounted Wi-Fi, as opposed to Mi-Fi or personal hotspots not mounted in the vehicle. We’ll take half of that additional 18%, or 9%, and add it the original 18% to speculate that in reality, like 27% of all vehicles that passed the Bailiwick Cafe and Market in the last week were equipped with on-board Wi-Fi.


Of course, I could be wrong. And, I’m not really a Chief Data Scientist. But these two facts aside, feel free to use this analysis any way you’d like.

Mobility Field Day: Glimpsing a Complex Wi-Fi Future

          Take me home mamma, and put me to bed. I have seen enough to know that
I have seen too much.
                      (Announcer in “League of Their Own”)

Depending on where you are on your WLAN career arc, what I’m about to say may or may not make you a bit uncomfortable. That’s not my goal, but there are some complicated times a-coming, my friends. I’m writing this just a few days after I wrapped up participating in Mobility Field Day 1, and you can’t help but leave the typical wireless Field Day  event feeling like you’ve looked directly into the future of the WLAN industry a bit.

I’ve been known to throw out lofty observations like “Wireless Is So Not About Wireless Networking Anymore.” Then there was my white-hot Napkin Drawing. Even when I’m in the thick of doing wireless, I can’t help but zoom out to 10,000 feet and try to see the Big Picture of Wi-Fi. That big picture has certainly changed since the early days of 802.11, and you could say that my journey is really just riding the evolution of wireless networking such as it is. What I saw at Mobility Field Day is more evolution, and a few years from now we’ll look back at and think “yeah, that was cool… but not SO BIG of a deal in retrospect.”

Yet, in the here and now, things that are coming our way ARE big deals. They are still new, unfamiliar, thrilling, cool, and need to be learned and assimilated into our daily Wi-Fi Pro mindsets. Here’s a few “Wow Topics” that jumped out at me during MFD:

  • Ventev’s Street Furniture Wi-Fi As demands for wireless networking become more pervasive far and wide, the question of “so, how do we put it THERE?” gets asked a lot. Ventev has a really interesting line of outdoor antenna solutions coming out later in the year, as shown in the linked video.
  • Nyansa’s Voyance cloud-enabled analytics. The intro and overview to this fascinating and innovative approach to analytics, support and Wi-Fi troubleshooting is here. The demonstration and accompanying discussion is here. Watch for more coverage of this interesting startup, and it stands to reason that others are likely to follow the example of cloud-enabled multi-site data correlation as Nyansa’s baby gets exposure and customers.
  • Cisco Connected Mobile Experience (CMX) Cloud version. There is just sooooo much to CMX and so many different applications. I love that some of the complexity is moving to the cloud (please, God- let Prime Infrastructure go there too, soon). Video is here.  Cisco also wowed with a presentation on Flexible Intelligent RadiosWatch this video, and you’ll agree that things are getting pretty complicated in WLAN land.

Also in the bucket labeled Really Cool, and Quite Different: had a great session with Google on their OnHub approach to consumer Wi-Fi (it would also be at home on Star Trek), and Aruba Networks’ Chuck Lukaszewski talked more on 802.11ax- which may well be the most disruptive and complex standard of our careers (for many of us) when it gets here.

It was an exciting week, and I’ve just tipped the iceberg here. And like I said… these discussions show just how exciting the short future is in many directions for our Wi-Fi world.

A Little Point-to-Point Bridge Saves The Day

Last weekend I was trying to finish up an IP CCTV project at one of my favorite customer sites. Here, an electrician was supposed to run the UTP and I would terminate and test it before I connected cameras. It should have been a straight-forward endeavor, but it got weird. I blame my own lack of attention to detail in telling the electrician EXACTLY where one wire needed to go. Because I didn’t, he put it someplace that was easy for him, but impractical for the application. The camera would somehow have to see around a substantial corner if I mounted it where the wire landed.

Allow me to leverage my Enormous iPad Pro and $700 pencil to make a simple site drawing:

Do you see the problem? There was really no practical way to get the UTP extended to where it needed to be, which would be right about where the outlet is drawn (about 10 meters away). Hmm. I had a good station cable that happened to be in the wrong place, and I had an electrical outlet under an overhang where I needed the camera to go. My wheels started to turn…

Are you starting to smell what’s cooking here? Let’s add a couple of things to that world-class drawing.image

By golly- that just might work.

Being a well-connected Man of Action, I happened to have a couple of 5 GHz Cambium ePMP 1000 in my bag of tricks. Sure, some might say the bridge link I was about to build– spanning all of around 30 feet– borders on overkill for this application. But you do what you gotta do, and I don’t really like wireless cameras. But I do like good point-to-point links for wired cameras.

The Cambiums are an elegant, cost-effective way to do links this short as well as miles longer if things line up right for you.  I updated the firmware on the bridges, gave them the simple config they needed to take their place on my network, and made sure the channel in use wouldn’t conflict with the business WLAN in place.

After a quick trip to Lowes, I was fairly pleased with my solution.



That 8″ square electrical box houses the power injectors for both the camera and the bridge, It will probably get painted along with the box the camera is mounted on to better blend in with the white of the overhang, and the owner blessed this unconventional setup as the camera is really important to them.

So how does it work? Though there is still a bit of camera alignment to be done, it’s a pretty good view from the camera.  This particular view is from a remote viewing app, but at the DVR the image is crystal clear and never stutters or drops. After a few days of testing, this link performs as well as a patch cable.


Like I said… sometimes you do what you have to do.

One in one hundred and fifty three quintillion.

An excellent take on RRM, from a fellow professional whose opinion I trust and value. Have a read.


RRM – a common term for Radio Resource Management – or the set of algorithms that set the channel and power level of your Access Points in an automated fashion. You’ve heard it all before, “RRM is broken, RRM picked the wrong channel, RRM hates me, RRM isn’t right for my network”. The reality is that RRM:

  • Isn’t dumb
  • Doesn’t hate you
  • Doesn’t love you
  • Doesn’t feel anything for that matter

As it turns out, RRM isn’t even smart. It has no feelings, passion, hate, love, real, imagined, or otherwise. In fact, RRM is just a series of algorithms that are built to do one thing – whatever you tell it to. RRM is a framework, meant to be built, adjusted, tweaked, and tuned. To be fair, there are two major topics that tend to give RRM a bad name and they are:

1) Every vendor implements RRM differently. This…

Extreme Networks Makes the Case for 802.11ac Wave 2

With Wi-Fi technology constantly improving, it’s easy to stop paying attention to what incredible things are really happening for WLAN users. And incredible things are happening. With the arrival of 802.11ac’s Wave 2, we see new wheels put into motion for wireless users, and paths that the wireless industry had started down being turned into legitimate highways. 802.11ac Wave 2 is big news, and businesses are benefiting from its transformative nature, as over-viewed in a new eBook published by Extreme Networks.

As a wireless architect who builds WLAN environments of all sizes, I see first-hand how modern Wi-Fi enables new workflows and allows businesses to re-invent their processes as wired Ethernet gets pushed increasingly to the margins. Wireless connectivity has become the access method of choice for a huge swath of the business world, and Wave 2 is very persuasive to those who haven’t cut the cord yet. As highlighted by Extreme, it’s not just about signal coverage- or even speed- any more with enterprise Wi-Fi. Wave 2 also brings impressive capacity that further makes the case that businesses truly can run their operations over well-designed wireless networks, while enjoying the benefits of portability and mobility. With data rates topping 1.7 Gbps in ideal conditions, wireless traffic is forwarded with great efficiency in Wave 2 environments.

Extreme’s eBook makes the point that Wave 2 delivers a number of new or improved technologies, and these get even legacy client devices on and off the network quicker. Wi-Fi is still a shared medium, but that notion is getting blurred a bit with Wave 2, for everyone’s benefit. Multi-User MIMO (MU-MIMO) is rightfully getting its share of media coverage, as for the first time we have the capability for a single access point to service multiple clients simultaneously. Like with Wave 2’s impressive top-end for data rates, there are many factors that have to line up for MU-MIMO to live up to its capabilities at any given instant. But even though it may not be leveraged for every client and every transmitted frame given the variability of wireless, there’s no disputing the aggregate performance gains to be had by MU-MIMO. It really is exciting stuff, even to those of us who have seen it all when it comes to WI-Fi.

As businesses of all types consider whether Wave 2 is worth upgrading to, Extreme makes some good points. With more delivered network performance per AP, even for older non-802.11ac client devices, properly designed Wave 2 environments can significantly up the return on investment for the same spend as 11ac Wave 1 or 11n, if you negotiate your discounts right. If you’re sitting on an 11a/g or even early 11n network, making the jump to Wave 2 may be easy if your cabling plant and switches are up to date. Even if they’re not, it’s not uncommon to find that when planning for a new high-end wireless network, you can decrease your wired Ethernet expenditures as you make the jump. Everyone has their own OpEx/CapEx/TCO paradigm to define and muddle through, but Extreme gives pretty good food for thought in their eBook as you wrestle with your own situation.

Yes, Wave 2 has a business story to tell. Efficiency, performance, more-for-the-money, and so on- yes, those are all valid and noteworthy. But the Wave 2 story is also exciting at the user level. BYOD is an established fact of life, and in reality it’s more like Bring Your Own Many Devices for most of us. Our users have a slew of devices of various types and purpose, and 11ac Wave 2 helps with the overall Quality of Experience. Better cells are a tremendous asset to the end user, especially when those cells can self-leverage their best qualities for different device types.

Just remember that Wave 2 isn’t a design, or a deployment scenario. It’s a really awesome technology to be used to solve business problems and to facilitate business operations. As Extreme points out, Wave 2 is part of a bigger technology evolution story that features not just better Wi-Fi, but also switching developed just for 11ac, new analytics capabilities, improved security options, the Internet of Things, and (depending on your needs) impressive SDN and cloud tie-ins. Nothing under the network sun evolves in a vacuum, and Wave 2 fits very well with other advanced enterprise developments. Whether it makes sense for you to consider the move to Wave 2 is ultimately your call (and you’ll like get there at some point anyway). Extreme’s eBook on 802.11ac Wave 2 is an easy read, and does a pretty good job of telling the story of Wave 2 from a few different important angles.

The Soon To Be Famous Cocktail Napkin Wi-Fi Big Picture

Get it while it’s hot… Print this baby out and put it on the break room fridge. Staple it to the helpdesk manager’s forehead so he sees it when he looks in the mirror, or have it printed out on a T-shirt that’s two sizes too small, so it accentuates your six-pack abs. What you’re looking at is the proceeds of a discussion I recently had, where I pontificated about how most “wireless” problems really aren’t wireless problems, even though ALL network problems “feel” wireless to the average user.

The Wi-Fi part of the story certainly can be temperamental on occasion, sure. But on a well-designed Wi-Fi network attached to a well-designed LAN, the overwhelming majority of user problems are going to be individual issues. When things do spin out– and multiple Wi-Fi users feel the pain– that’s when you want to turn to this masterpiece created on my enormous iPad Pro to remember just how complicated “Wireless” can be. (I missed “captive portal” as problem source…)


For $5 a Month, Verizon Wireless Will Give You a Workaround For Their Bug

Reference Number: <removed>
DATE/TIME: 2016-03-09 19:36:29
Chat Transcript

Verizon : Thank you for contacting the Verizon Wireless Chat Team regarding your account. How can we help you today?

You : I’m not having luck managing usage control on one of my lines. Keeps saying Function not available now but I need to implement a data control

DAMON : Oh my! I understand your concerns in regards to usage controls. No worries! I will assist you with this matter. Could you provide your mobile number please?

You : Line is <removed>, keeps going way over plan and I want a 2 GB limit on it. Main line is <removed>

DAMON : Thank you for that information. Allow me a moment to check into this matter for you.

You : thank you

DAMON : You’re very welcome!

DAMON : I am showing that the function is unavailable at this time. What I can do is recommend you to FamilyBase. This is a feature that allows you to set limits to calls, texts, and data usage. It is only $4.99 per month with the first month free. Would this be ok?

You : Why would the function be unavailable? That’s the problem I’m trying to get help with

DAMON : There may be a bug that was discovered with it and it is being fixed at this time.

You : For the amount we spend on this plan, I really dont want to spend more on a bug onVerizon side, that doesn’t make sense

DAMON : You’re not. What I can do is check and see what I can do to decrease your bill as well.

You : Please don’t. I don’t want to revisit the plan. I’m looking for a control on one problem line with data, that’s all.

DAMON : The system has a bug which is why it isn’t available at this time. I do apologize for the inconvenience.

You : So shouldn’t the $5 feature, if that’s a workaround, be free?

DAMON : It is free for the first month of use.

You : Right… and then it’s not and we’re paying for a workaround– that doesn’t make sense

You : we pay almost or over $1K per month here, this is really odd to say we have a fee for a broken feature that should be free

DAMON : You would have to wait until the bug is repaired to get the control set.

You : meanwhile the line gets abused and we incur the charges because the control can’t be set, and we’re identifying to you that we need it. We are in a no win. What is ETA for the fix?

DAMON : At the moment, I have not been informed of the ETA.

You : So… we faithfully, for years, pay tens of thousands of dollars on this bill. And when we need help, because there is a system bug, our only option is to pay Verizon to work around that bug with a feature that COULD be offered as a no-cost workaround for a customer need, but Verizon doesn’t see that as an option? Really?

DAMON : The charge is only applied after the free first month of use. You could use the feature until the bug is fixed. There will be no charge if you remove it before the free month is over.

You : This is lunacy. There is no ETA on a bug fix. The onus is on us to cancel the feature to not get charged and likely be right back to incurring overages. Damon, this is nonsense, and is the worst in customer service. It’s just terrible from this end to fathom how this could make any sense to Verizon

Then he bails out… abruptly, with no more dialogue.
