Sounds like a great system Mogens, and very similar to what I want.  

However, my project involves about 600 bays in a compound to store cars, so I 
can't label the bays as you suggest.

I'm looking using a WIFI setup with access points dotted around the fences.  
Does anyone have any recommendations for outdoor WIFI access points and data 
on what area they cover?
