On October 3, 2014, the US Federal Communications Commission (FCC) fined Marriott $600,000 for unlawful use of a "containment" feature of a Wi-Fi monitoring system to deliberately interfere with client-owned networks in the convention space of its Gaylord Opryland Resort & Convention Center in Nashville. The scheme disrupted operation of clients' mobile telephone hotspots by sending fraudulent Wi-fi de-authentication packets. Marriott International, Inc., the American Hotel and Lodging Association and Ryman Hospitality Properties responded by unsuccessfully petitioning the FCC to change the rules to allow them to continue the willful jamming of client-owned networks, a position which they were forced to abandon in early 2015 in response to backlash from clients, mainstream media, major technology companies, and national mobile carriers.
