Subject: Marriott wifi blocking

Saw this article:

http://www.cnn.com/2014/10/03/travel/marriott-fcc-wi-fi-fine/

The interesting part:

'A federal investigation of the Gaylord Opryland Resort and Convention Center in Nashville found that Marriott 
employees had used "containment features of a Wi-Fi monitoring system"
at the hotel to prevent people from accessing their own personal Wi-Fi networks.'

I'm aware of how the illegal wifi blocking devices work, but any idea what legal hardware they were using to 
effectively keep their own wifi available but render everyone else's inaccessible?

David,

All major WiFi players have some seek-and-destroy function to prevent rogues on/near their network.  It is the 
responsibly of the IT folks to determine how aggressive these settings are, and to what needs deauth sent to clients.  
These can be very effective in dropping sessions from clients on unauthorized systems.  

The question here is what is authorized and what is not.  Was this to protect their network from rogues, or protect 
revenue from captive customers.
