Why Lee Badman’s website is a must read with Glenn Cate

Lee Badman’s “Wi-Fi Question of the Day” has been a great resource and in this review, Glenn Cate gives us more reason to follow Lee and why his website is a must-read for every Wi-Fi Professional.

Want to listen to the interview instead? Go HERE

Matthew Casteel: Glenn Cate, welcome to the show. What Wi-Fi blog review do you have for us this time?

Glenn Cate: Hey, Matthew! I’m doing great and thanks for the welcome. We’re going to review Lee Badman blog (wirednot.wordpress.com).

Lee’s a WLAN architect who works at a large University in upstate New York. He also blogs for network computing and IT toolbox. He is CWNE#200 and his Twitter handle is @wirednot.

Some of you may have heard Lee as a presenter at the depth of different WLAN conferences. He’s spoken at WLPC 2016 and 2017 and one thing about Lee is he doesn’t beat around the bush. He tells you what he thinks about things and whether he likes it and what he doesn’t like about it.

I like his website page. I’m a ham radio operator so I love antennas and he’s got a picture of a radio tower and Florida Prince Haiti where he did some work a few years ago. Wirednot gives us honest and forthright opinions of products and services with his usual twisted humor and sarcasm.

Wirednot gives us an honest and forthright opinion of products and services and usual twisted humor and sarcasm.

His latest blog for example where he says, “will reliability be prioritized before Wi-Fi’s whiz-bang future gets here?” Anyone can discuss the ongoing technologies with Software-Defined Networking in the Wi-Fi space, but he says “Wi-Fi vendors need to fix this stuff now.” Lee aptly puts that a house that is built on sand cannot stand. So, good point on that!

Anyway, he’s a great speaker, writer and I really like the stuff on his website because he just gives honest and open feedback about the technology.

He also quotes complaints about some Wi-Fi or technology that does not work well in an honest and straight forward way. So, I love his Wi-Fi blog. He just had a recent blog on WLAN controller upgrades and bugs that they don’t always fix and that vendors need to work on that. Lee’s website is a must-read.

Matthew Casteel: That’s great! Anything else we don’t want to miss on the site?

Glenn Cate: Lee really gives back to the WLAN community and he does this a couple of different ways on his website. He’s got a #WiFiQ on Twitter where he put out a “Wi-Fi question of the day”.

Lee really gives back to the WLAN community and he does this a couple of different ways on his website.

So, you need to follow him on Twitter to get his Wi-Fi question of the day. It’ll be something simple like what kind of data rates you send to or what type of vendor APs you use? They are more detailed and it’s always great and refreshing to look at.

He has a little snippet on his website for his “Wi-Fi Question of the Day”. Follow Lee on Twitter @wirednot and check out #WiFiQ to give you some information.

There’s also the comic side of Lee. He got a tab on his website called “OH MYSTICAL FI”. They are short little silly cartoon strips about someone talking to mystical Wi-Fi and you’ll just enjoy looking at these. Sometimes just we need a little laughter on a day especially when our code upgrades don’t always go right.

Glenn Cate understands the detail and complexity of WLAN design and thus, has achieved CWNE #181, Ekahau ECSE #605 and other IT certifications from Cisco, Microsoft, CompTIA, Lenovo and Stanley HealthCare. You can connect with Glenn via Twitter.

Deploying Wi-Fi Networks in the Real World with Jason Hintersteiner

Jason Hintersteiner, a Wi-Fi engineer, presented at #WLPC US Phoenix in 2016 about deploying Wi-Fi Networks in the real world, the theory, and practice.

You can watch the full presentation HERE.

Steps in Deploying Wi-Fi in the real world

The first step is admitting you have a problem. I’m going to admit that we are powerless as Wi-Fi engineers to really deploy in the right way. Where does it start? It starts with the customers. They have a lack of understanding of Radio Frequency (RF) and how Wi-Fi works. Most of my customers have lack understanding of how networking works. They got conflicting priorities in aesthetics.

But it’s not just the customers that are our problem, it’s us as well. We’re highly trained people in our craft and we’ve been doing this forever, some of us longer than others. We know better than everybody else, how it’s supposed to be done.

We’re also biased. We choose the vendor equipment we prefer or in some of our cases, the vendor equipment of the people we work for. We don’t always choose the vendor equipment that’s actually most appropriate for the job.

“I’ve certainly worked on a wide variety of cases where certain vendors are more appropriate than other vendors.”

  We also have commercial pressure to sell more versus selling what’s right. We also cheat. We take shortcuts especially if we’re not getting paid.

Let’s proceed with the steps that we normally go through. All the books and the CWNA have written and told us how we should do design and how we should deploy.

Step 1: Gather requirements and constraints

I’m a systems engineer with a background in training, so I’m a huge fan of gathering requirements constraints but this is really hard. They’re not static, they are fluid. The requirements often change during the project.

I don’t know how many of you have worked on surveillance systems, but I have yet to work on a surveillance project where people are mounting cameras. They are “not” increasing the number of cameras while you’re doing the design.

We get to work on one. However, the requirements actually changing over the life of the network. We have networks that are five years out.

Many requirements are unstated or assumed. How many people in their designs make sure that there’s excellent coverage in the bathrooms?

Keep them up if you’ve ever actually explicitly been told to do so in an RFP or by a customer. I’ve never been told that. I always put good coverage in the bathroom, so I’ve never actually gotten that in aspect.

A customer doesn’t always know where the building materials made of. Sometimes, they don’t even know how the network is going to be used, what number and types of devices and what kind of applications.

Step 2: Perform a Predictive Design

Predictive modeling is an oversimplification. We oversimplify the environment because we guess the types of walls. We often don’t draw in bathrooms, closets and other kinds of small features. We’re guessing it is the absorption and reflectivity on each band. We don’t account for things in the actual environment like furniture, appliances, mirrors, and big bags of water walking around.

What about external interference? You can’t do that in a predictor model. We also oversimplify our deployment constraints. Can wiring actually be run to where we plop down those APs on the model? Will the installer actually deploy based on your specs?

Step 3: Perform a Pre-Deployment Site Survey

We don’t want to rely on only one when we want to perform a site survey. We want to go to the site and take measurements, measure the RF through walls.

This isn’t commonly done especially in the small-medium business because the survey doesn’t happen if nobody wants to pay for it.

There are also installer limitations especially as a device manufacturer. We’re not the ones doing the installations, it’s our customers who do it. You have to rely on them to do a lot of this work. Do they have the right tools? Do they actually know how to use the tools even if they have the right tools?

When they do a walkthrough, it’s often to discover basics. Where can I actually run cable not how the RF is gonna propagate?

Step 4: Perform the Installation

Deploying to spec. Does the Installer cut corners and move your APs? I’ve heard several instances of that. Does the installer actually follow your carefully planned channel and transmit power scheme when they configure the equipment?

Cabling. Can wiring be run or is your cable actually validated? Are your connectors properly seated?

Your environment. Has it changed since the design or the survey was done?

Step 5: Perform a Post-Deployment Site Survey

Let’s go back in and validate and assess where we are. Unfortunately, this isn’t commonly done. It won’t get done if nobody pays for it. Often they’re in a rush to finish the job, especially on a new construction where the constructions already delayed and now they’re piling in the Wi-Fi at the very last minute.

Installer limitations. Are the tools available and do they know how to use them? And when they do any testing for basics, can I get out to the Internet? Do I actually have just any coverage at all? In certain sections, it’s a spot check, it’s not rigorous. If there is a problem what are they doing about it?

What can we do as Wi-Fi engineers? You just place the APs randomly and let RRM just figure it all out for us. We could blame it on those ill-defined multi-user MIMO algorithms.

Better yet, we’ll just wait until 802.11ax comes out and retire to @wirednot’s farm to go after a simpler life. Let’s not do any of those things.

What do we do? We do the best we can. We standardized as much as possible. We pick out our set of preferred equipment, our APs, switches, routers, and controllers for particular applications. Then we have to be flexible and actually adapt them to whatever requirements we actually know about.

We’ll also try to build a robust design. We designed those unstated requirements and follow best practices. We build margin and excess capacity. We also keep learning and refining our craft which is why conferences like this are great.

Failure is not an option.

As a field engineer, I’ve got to figure out how to make it work even with the lack of requirements, a lack of data and a lack of survey stuff. Installers who are in way over their heads, I deal with these stuff on a day to day basis.

But failure is not an option. So, we have to figure out how to make it work despite all of those things.

I’m gonna close with a Wi-Fi engineer serenity prayer.

Gods of Wi-Fi grant me the serenity to accept the things I cannot change: lack of requirements, lack of budget, lack of time. The courage to change the things I can: following best practices, following standards, following a robust design principle and the wisdom to know the difference. Also, the list of not to slap the customer across the face.

“Failure is not an option – we make the Wi-Fi work as best as we can no matter what”

Here’s a great shot Lee took of his Sidekick

This Changes the WLAN Site Survey Game

Lee Badman, on his blog WiredNot shares why he thinks the Ekahau Sidekick™ “changes the WLAN site survey game”.

“Whether a single Sidekick is shared among a couple of teams or several teams with a mix of Mac and Windows PCs all have Sidekicks, the new magic strips away all of the variability that came from a mixed bag of adapters at survey time while also providing long battery life (and a platform from which a slew of expected feature evolutions) which can only lead to better wireless when put in skilled hands.

And it looks darn pretty.”

Lee also wrote an another article for IT Toolbox titled “The WLAN Survey Fat is in the Fire- Ekahau Sidekick”

“Sidekick has the ability to be a game changer, if the market accepts its price point, warranty terms, and form factor…”

Your New Survey BFF

WiFi Nigel a.k.a Nigel Bowden highlights the weight, size, specs and many of the advantages he sees with the new Ekahau Sidekick™

“As a techie, I must admit to having found the SK disappointingly easy to use   It literally is just a case of powering up the SK, connecting it via a single USB cable to your laptop and firing up your copy of Ekahau ESS. That’s it. Throw the SK over your shoulder and start surveying…”

Nigel also creates a nice Pros & Cons list… Here are some of the potential Cons he highlights:

Cost

Hardware Support

Weight

Heat
