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

What are your New Year’s resolutions? Are you going to take up one of the ones listed above? Let me know in the comments below.

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.

CTS 017: Francois Verges and Roaming

In This Episode

In episode 17 of the Clear To Send I would like to welcome Francois Verges of SemFio Networks.

We talk about an introduction to roaming.

Some of the topics we discuss are what customers need to know about WiFi roaming, how clients decide to roam, and what it means to roam.

Sometimes there are also problems to solve about roaming. What happens when a client doesn’t roam? We talk about some amendments that help with improved roaming.

RF Fundamentals

In this main segment, I talk about RF Fundamentals.

There are four characteristics of RF signals and that is:

  • Wavelength
  • Frequency
  • Amplitude
  • Phase

There are nine RF behaviors to know about:

  • Absorption
  • Reflection
  • Scattering
  • Refraction
  • Diffraction
  • Attenuation loss
  • Free Space Path Loss
    • Free space path loss formula
