May 29, 2016 CTS 039: When and How To Use Spectrum Analysis

Thank you for joining us on another great episode. The topic of episode 39 is when and how to use spectrum analysis.
Spectrum analysis is a crucial part of wireless site surveys and for troubleshooting. When performing spectrum analysis as part of a wireless site survey, an engineer can determine which areas contain sources of interference that can greatly degrade the performance of a wireless network.
Some interference is non-802.11 traffic. Wireless NICs within devices cannot demodulate these signals. If a transmission occurs with interference present, the frames are corrupted.
It’s important to know the different kinds of interferences that can exist.

* Sporadic (happens only at specific times). An example is bluetooth
* Constant (the interference is there all the time). Example: Wireless Video Camera
— Both can be disruptive to the Wi-Fi if the duty cycle is high
— There is also the width of the interference to validate.
* Do not forget to watch out for interference from other Wi-Fi networks (even yours…)
* Duty cycle
* ACI

May 23, 2016 CTS 038: Robert Boardman, Hub Holster, Cisco Live, and RRM
Robert Boardman is my special co-host for Episode 38. Robert is the creator of Hub Holster which is a great alternative to using velcro on your laptop to hold up a USB hub during a wireless site survey. I assisted in providing measurements for my own USB hub and after a few back and forth in communication I have a fully functional USB hub holder. It was printed using a 3D printer.
We discuss how the idea of the hub holster came to mind, the process that goes into building a hub holster, and other features we may want to see.
Both Robert Boardman and I will be heading to Cisco Live 2016 in Las Vegas. This will be my first time attending. I’m excited to meet others in networking and hope to get a podcast episode recorded with other attendees. If you are attending Cisco Live 2016, please let me know!
Our last topic of discussion is about RRM. Robert and I have been thinking about really learning the ins and outs of RRM. Our goal is to deploy RRM and collect the necessary metrics to determine whether or not RRM helped in our scenario.

May 02, 2016 CTS 036: How To Get Started In Wireless
Following up with Wes Purvis’ talk from MFD1 on getting started in wireless, I wanted to do my own on the same topic. In this podcast, I will go over my own experiences in a high level step by step on how I got started in wireless.
I didn’t take a direct path to wireless and I actually don’t do wireless ful time. I am currently a network engineer who does do quite a bit of wireless work. But the path to this point took a while. It wasn’t instant.
I started from the very bottom working as a computer parts salesman. My next role I began working as tech support. Working in tech support allowed me to learn how the end users worked on the network, what kind of applications they use, and how they use it.
After my tech support role I then landed a systems administration job. From there I learned about servers and operating systems. What’s great about knowing sysadmin work is that I was able to understand Active Directory for authentication. Many wireless systems use Active Directory for authenticating users.
Listen in on this episode to hear more about how to get started in wireless.
There are just eight steps I highlight here which I go into briefly. Each one can certainly have its own episode.

* Get experience dealing with end user issues.
* Learn networking from the wire perspective.
* Pick up a CWNA book.
* The learn vendor material.
* Get a lab. Use wireshark.
* Start volunteering yourself for wireless work.
* Write about wifi
* Network with other wifi professionals

April 25, 2016 CTS 035: Mobility Field Day 1 – It’s A Wrap
Mobility Field Day 1 brought together different minds in the wireless industry in one room and one presentation. We saw presentations from different vendors and other wireless leaders.
Actually, not even all of them were really wireless but had their ties back to wireless in one way or another.
All I have to say is that it is a great time to be alive. We’re seeing wireless advance greatly and many vendors are doing creative work in this space.
I’ll let you listen to the podcast episode to hear what I’m talking about.
If you haven’t seen any of the videos from MFD1, please head over to the [Vimeo page] to get educated.
