I cover the tradeshow space pretty regularly, so here's some additional context for those interested: It's worth noting that Smart City, the company at question here, is the largest company of its kind in the tradeshow vendor space, and represents convention centers around the country—including in Las Vegas, the largest tradeshow market due to CES a number of other big conventions. They decided not to fight the fine: http://associationsnow.com/2015/08/fcc-fines-expo-vendor-750k-blocking-wireless-hotspots/ http://associationsnow.com/2015/08/fcc-fines-expo-vendor-750... Last year, Marriott received a slightly smaller fine for the same reason, but this one is arguably a bigger deal because of the vendor's reach. The common party line for such networking issues like this is that they're trying to prevent hacking or network manipulation issues—that was Marriott's take on it, at least—but considering the alternative costs so much, the argument seems pretty transparently flawed.
