Locate an access point and create coverage area heat map

[erotavlas]

Hi,
I work in a school and I would like to locate some access points which position is unknown.
I read many guides about how to do this task. One very interesting guide for linux is this http://blogs.interfacett.com/finding-rogue-wireless-access-points-kali-linux
that combines cheap antenna with the power of kali linux.
I found some stand alone products like this https://www.anixter.com/en_us/products/AIRCHECK-G2-KIT/NETSCOUT/Data-Test-Equipment/p/704154, but they are extremely expensive.
Moreover, I would like to have an heat map of coverage area. I found this interesting guide for windows http://www.howtogeek.com/165614/how-to-create-a-wi-fi-heatmap-for-network-analysis-better-coverage-and-geek-cred-galore/.
Do you have any advice for linux?
Thank you

The first link you gave simply uses airmon-ng in Kali linux. airmon-ng is available in Ubuntu or, for that matter, any other Linux distribution I am aware of. It is pretty complex and a bit tricky to set up.

Perhaps you'll consider wifi-radar. http://wifi-radar.tuxfamily.org/images/wr-v2.x-25-main_win.png It is available in the Software Center or, for old school users, from the terminal:
sudo apt-get install wifi-radarThere is also kismet, which is also a bit tricky to get going: https://linuxkismet.files.wordpress.com/2008/08/kismet1.png It's also in the Software Center and, as well:
sudo apt-get install kismet kismet-plugins

... and to add that we do not give support for or allow discussion of it on these forums. ;)

Thanks chili555.
