CTS 022: Jason Hintersteiner Part I – Small & Medium Business WiFi

SMB WiFi text over a desk

Jason Hintersteiner joins the Clear To Send podcast to talk about how he got started in WiFi after the thought of having to move to Europe for his employer. From there Jason brings up his experiences working with small & medium business WiFi. This is Part I of a two part podcast interview.

The SMB space requires a different approach to WiFi compared to a large enterprise or large educational institution. While the process might be different, one thing is certain – Jason and I agree that a wireless professional must know the basics or foundations of wireless before designing, installing and troubleshooting a wireless network.

I ask about the tools Jason uses on his Windows laptop and what his design methodology is, such as 80, 40, and 20 MHz channel widths.

CTS 021: WiFi With Keith Parsons

Laptop up against books

In This Episode

I have the pleasure of sitting down and interviewing Keith Parsons on the podcast. When I first got started in WiFi, it was Keith’s podcast and resources from WLANPros.com that gave me the right direction. Keith Parsons is CWNE #3 and runs WLANPros.com and also the founder of the WLANPros conference.

In this episode, Keith talks about how he got started in wireless to where he is now. He provides insight into how he designs WiFi in K-12. Along with that are his expertise on 1 AP per classroom and placing APs in hallways.

Near the end of the episode, Keith provides his tips for those just getting started in WiFi, what tools he’s currently using, and more about the upcoming WLPC conference in February 2016.

Defining Channel Overlap

Defining Channel Overlap

Channel Overlap is a heatmap within Ekahau Site Survey. It tells you how much channel overlap (both co-channel and adjacent channel) you have on your predictive or post-site survey. The criteria is defined within the Coverage Requirements window.

Coverage Requirements can be found by going to Project > Coverage Requirements.

By default, the application will allow for channel overlap. By setting the Max number for Channel Overlap to 1, the application will tell you if there is channel overlap heard from more than one access point.

Viewing Secondary Coverage

Another tip Keith provides is viewing secondary coverage. By default, Ekahau shows you primary coverage. But what about if you’re designing for VOIP? Or what if you want to determine coverage for redundancy in the case of an access point failure.

By clicking on Options and then using the drop down to change from strongest to 2nd strongest, which is located at the bottom, the Signal Strength heatmap provides a visualization on secondary coverage.

Thanks For Listening

I hope you enjoyed this episode with Keith Parsons. He provided a lot of knowledge bombs for us on WiFi design, tips on using Ekahau, and his valuable insight.

CTS 020: 5 New Year’s Resolutions For Wireless Engineers

In This Episode

We’ve made it through the first week of 2016. It’s a good time to look back at our accomplishments of 2015 and to look forward for 2016.

I’ve created a short list of 5 New Year’s resolutions for wireless engineers. It is not in any particular order.

  1. Attend an in-person event
  2. Become a speaker/presenter
  3. Get certified
  4. Start a blog
  5. Be Bold

Bonus: Start your own lab

CTS 019: WiFi Predictive Modeling

In This Episode

The first episode for 2016 is going to be about Wi-Fi predictive modeling – how I plan my wireless networks.

But before we get into the meat of the episode, I’d like to share my new year resolutions:

  • CWAP
  • CWDP
  • More learning
  • More podcasts!

Man, I have a lot to work on. What are your resolutions?

My 2016 predications:

  • LTE over Wi-Fi*I meant to say LTE-U and LAA* to gain traction
  • We’ll be working with more poor Wi-Fi
  • Someone will be fined over blocking Wi-Fi
  • Wi-Fi calling will take off

Predictive Modeling

Predictive modeling is a method in which a software application is used to predict the number of access points required on a floor plan based on user inputted capacity and coverage requirements.

As the phrase says, it is a PREDICTIVE model. A wireless installation should be verified to end user requirements.

My application of choice is Ekahau Site Survey.

Some things to consider in your predictive model using Ekahau:

  • Setting Capacity and Performance requirements
  • Setting Coverage requirements
  • Importing a floor plan
  • Setting scale and alignment points
  • Adding a coverage area
  • Adding access points
  • Optimize placement
Configure your network requirements.

CTS 018: Get Off My Channel

In This Episode

I want to talk about channel planning and channel re-use. More importantly, why you would want to even consider this, how it should be done and what tools you can use to do it.

As an introduction, I briefly go over the available channels in the United States – specifically the non-overlapping channels in both 2.4 GHz and 5 GHz frequencies.

At the end of the episode, I go into the importance of planning. My tool of choice here for wifi planning is Ekahau Site Survey.
