It would seem that somewhere along the line the rumor got started that predictive surveys are magical, mythical things that are conjured out of thin air by the power of an 'easy' button.
If I had a nickel for every time I've had to level set someone's expectations on how long a predictive survey should take, could take or will take; the stack would be pretty high.
I made an informational video explanation on what a predictive survey is and the difference in the length of time to define all of the RF obstacles when the wireless engineer has a CAD file of the floor plan vs. any other image file of the floor plan. The video is eight minutes long and has a disclaimer at the end for all the YouTube people that feel the need to tell me what I left out, or how I didn't explain it right (according to them).
This video is not intended to be an all-encompassing explanation of all of the phases of a predictive survey. The content is solely my opinion. Do not attempt to perform a predictive survey without having attended an Ekahau training class, preferably the Ekahau ECSE Design course.
