Huh?

"it will be able to determine the IP address, device type, downloaded 
applications, current location, and historical location of any device that 
searches for a Wi-Fi signal. "

No they won't. It doesn't work like that.

At most, they can track devices  or *maybe* applications that try to connect 
and have a rough location, based on the location of the WAP. 

Any system with an IP address already is not trying to connect. When your 
device shows you what WiFi is available that's based on a passive reception of 
broadcast SSID's in range. There's no communication between your device and the 
WAP unless you attempt to connect.

They certainly cannot tell what applications you downloaded if you never 
connect to their network. 

If you do connect to their network, well, network owners can do all sort of 
things; which is why you shouldn't be connecting promiscuously to all those 
networks.
