Locating wireless devices through spectrum analysis

Last week I attended the Certified Wireless Analysis Professional beta course.Â
It was an intense 3-day course that focused on the physical and MAC layers of wireless communication and emphasized both protocol & spectrum analysis.  Â
The best part was that I learned something that really surprised me...
In the video below, I interview Keith Parsons, founder of WirelessLANProfessionals.com, about locating wireless devices through spectrum analysis using both directional and omni-directional antenna.Â
In a nutshell, Keith said that it was easier to locate devices through spectrum analysis with an omni-directional antenna rather than a directional one.Â
This is because if the RF energy is equal in every direction around you, the only way to locate a wireless device is to physically move closer until you see the signal stregth rise -the higher the amplitude, the closer you are to the device.Â
Do you have a interesting tip, trick, or story about spectrum analysis? Add it to the comments section below.Â
