Excellent point, Rand- this is called “Body Fade” (for real) in the larger realm of radio direction-finding, a.k.a fox hunting. If you master it, it is very handy. But it does get a bit tougher when the rogue is above or below you on another floor.
FWIW, here’s a blog article I wrote that explains and shows an example of Body Fade in the real world for rogue hunting. https://wirednot.wordpress.com/2018/09/17/catching-up-with-netscout-at-mfd3-big-news-and-body-fade-explained/ Lee Badman | Network Architect (CWNE#200) Information Technology Services (NDD Group) 206 Machinery Hall 120 Smith Drive Syracuse, New York 13244 t 315.443.3003 e [email protected]<mailto:[email protected]> w its.syr.edu SYRACUSE UNIVERSITY syr.edu From: The EDUCAUSE Wireless Issues Community Group Listserv <[email protected]> On Behalf Of Hall, Rand Sent: Monday, January 27, 2020 8:00 AM To: [email protected] Subject: Re: [WIRELESS-LAN] Android Rogue Hunting App This is not a novel idea, but your torso attenuates enough signal to make a good "opposite" directional antenna.

Does anyone have any Android software products they recommend for Rogue hunting? Unfortunately Ekahau Mobile Survey (EMS) has been canned, so we are looking for alternatives to put to use on an Android tablet. Ideally it should be something simple to use, that allows non-technical users to quickly narrow down the location of rogues.
