Good wifi require tools. Simply put, a doctor is only as good as his tools. The doctor has lots of knowledge, but without a scalpel, that same doctor can’t do surgery. It is the same with a wireless network engineer.
No tools = low chance for good outcome.
Good tools = high chance for good outcome.
One of the tools that I use is the Fluke AirCheck.
Fluke’s description of the AirCheck:
“AirCheck™ Wi-Fi Tester
Wireless troubleshooting made simple in a dedicated handheld Wi-Fi wireless signal strength test tool.
- Dedicated, handheld 802.11 a/b/g/n/ac* Wi-Fi network tester with instant-on technology

- One-button Wi-Fi AutoTest quickly provides a pass/fail indication of the wireless environment and identifies common wireless signal strength problems
- See Wi-Fi network utilization by channel and quickly determine if it is 802.11 traffic or non-802.11 interference
- Quickly identify and locate wireless access points whether authorized or rogue
- Fully document your wireless troubleshooting session enabling fast trouble ticket resolution or escalation

* AirCheck Wi-Fi tester can detect and locate 802.11ac access points as well as validate 802.11a/b/g/n client connectivity by connecting to 802.11ac APs.”
In a twitter conversation including Devin Akin, Andrew von Nagy, Nick Lowe, and others, the question came up on what was under the hood of the AirCheck.
So I dug a bit deeper.
Before I move on to the AirCheck Goodness…Devin Akin is offering a webinar about the Fluke AirCheck July 16th. I highly suggest watching it. I will be.
So I dug a bit deeper.
I found that the AirCheck had the following:
Atheros 11a/b/g/n Mini PCI Mod w 2×2 MIMO. FCC-ID RYK-WMIA199N
So how did I find this out? The FCC ID. To sell a radio in the USA, each manufacturer has to have the radio approved by the FCC (which is the U.S. Federal Communications Commission). Each world region has its own governing body on what it will allow for transmissions of radio frequency and what it will not allow. All in the name of the greater good.
Here is the search page for the FCC:
Here is the FCC information on the Atheros Radio in the AirCheck:
I hope this helps!
I use the AirCheck as my first step in onsite troubleshooting. Checking for access points (or AP Stations), rogue AP Stations, signal, noise, locating devices, measuring attenuation through objects. It is an amazing wifi tool. I should get one for free from Fluke now right? ….Fluke? …. Hello?…*crickets*
