July 10, 2017 CTS 084: Channel Widths with Devin Akin
Devin Akin joins us on the show to talk about using wider channels on wireless networks. What are the pros and cons, what should we know when configuring wider channel widths and how does it affect the clients?

Channel Widths
Devin Akin joins CTS to drop some knowledge on channel widths. Devin is the founder if Divergent Dynamics, a Wi-Fi consulting company. But before that he got his foundation in the military, where he started learning RF. After the military, Devin founded CWNP which has now grown to be the vendor neutral certification in the technology industry. He soon pursued other roles in different companies to further add to his experience as a wireless expert.
In this episode, Devin talks to us about using wider channel widths in our Wi-Fi network. This episode is going to be very educational. We asked the question of how we got to using up to 160 MHz channel widths. So we get a bit of history into older wireless technologies, beginning with 802.11 prime.
As the market chases the highest data rates possible, Devin begins educating us on how channel bonding is used. The discussion will make you want to test this out for yourself on your wireless networks. Frames such as management and control will use the primary 20 MHz channel widths. Channel bonding was introduced in 802.11n which gave us 40 MHz channel widths and higher data rates. But with this we increase the noise floor and require higher SNR.
And we cannot forget about CCI and ACI which Devin definitely goes into. In our discussion we ask Devin how he approaches channel bonding in his design. What factors play into whether he’ll increase channel widths beyond 20 MHz.
And probably one of the most educational moments of the episode is learning about OBSS and the affect it has on wireless networks.
Listen in on this episode for much more and get ready to take notes.

Here are the Wi-Fi apps for Windows that Rowell and I use regularly when we are working at client sites or for any other Wi-Fi project. We certainly have our favorite apps and there are some we use on special cases but take a look at the list below and let us know what you think in the comments.
Metageek Chanalyzer

Spectrum Analysis software (For more, listen to CTS066, CTS039, CTS073)

Required a piece of hardware to feed spectrum information to the software

Wi-Fi Spy dBx
Cisco CleanAir AP (much better resolution)

Simple and user friendly interface

Different views

Waterfall view
Current spectrum view

Ability to record spectrum analysis
Can scan both 2.4GHz and 5GHz bands at the same time (if proper adapter is used)
Built-in Wi-Fi network scanner
Present channel utilization

Metageek Eye P.A.

A different way to analyze a Wi-Fi network

Very visual

Ability to capture packets (if proper Wi-Fi adapter is used – Airpcap Nx) and display different valuable statistics

How much the airtime is used? By who? You will see how much your neighbours affect you!
Compare size of packets with amount of data transfered. Helps to visualize that Wi-Fi generate tons of management traffic

Ability to import packet capture taken from other programs (Wireshark, AirTool, CommView…)
Ability to see the packets

With filter capabilities

Great to visualize issue and present to customers
Geat to gather statistics on how a Wi-Fi network is performing

Wi-Fi Apps for macOS
Being a Mac user meant not having enough apps to do your job. As a Wi-Fi professional, we rely on many apps to help get our jobs done. Fortunately, we have developers who hear the cry for professional Wi-Fi apps on macOS. Here’s a list of apps Francois and I use on a daily basis. This is in no particular order.
Wi-Fi Explorer
Great app developed by Adrian Granados who was interviewed back on 007. Double 007! This is an excellent Wi-Fi network scanner that is simple to use and updated regularly. It has built-in search functionality so you can find the network you’re looking for. You have the ability to add different columns to fit your troubleshooting needs and you can see advanced details such as information elements. This is a paid application.

Airtool
Another powerful app from Adrian Granados. It’s a menu bar application capable of capturing Wi-Fi frames using the Mac’s built-in Wi-Fi network card. From the app you select a channel to capture frames from, select the channel width, and you’re off to the races. It can be used with Wireshark, Cloudshark, and Mojo Packets. This is the fastest way to capture frames using a Mac. One of my favorite apps to use. Also, it’s Free!

Wi-Fi Signal
Adrian Granados strikes again! This is a menu bar application used to easily check the status of the Wi-Fi network you’re connected to. It can display information such as quality of the received signal, signal in dBm, noise, SNR, and current channel. It can send notifications of when you connect/disconnect to a Wi-Fi network and even if you roam.

Debookee
We interviewed the developer, Thomas Baudelet, in episode 70. This is a great app with a wireless module which displays details of Wi-Fi networks, displays statistics such as retry rate and Tx and Rx throughput. This app makes it easy to analyze other clients’ performance. This is a paid app.

iPerf
A free application to test throughput of your Wi-Fi network. What else is there to be said!?
Metageek InSSIDer Office (beta)
Currently in beta, Metageek has a macOS application that can scan Wi-Fi networks around you. It contains a search functionality to get through all the networks on the list. If you plug in a WiSpy dBx you can get a lite version of Chanalyzer. This is a paid app.

Terminal/iTerm2
Use this to SSH into your devices. You can build aliases and scripts to help you manage your network efficiently.
TamoSoft Throughput Test
Can operate as a server or a client. The server can be ran from macOS or Windows. The client can operate on macOS, Windows, Android, and iOS. It’s very easy to use and provides a visual throughput ...
