One of the members of the Federal Communications Commission, Jessica Rosenworcel, has asked the agency to investigate the Monday evening ban on journalists’ Wi-Fi personal hotspots at the presidential debate held at Hofstra University.

As Ars reported on Monday evening, the host venue demanded that journalists pay $200 to access the event’s Wi-Fi and were told to shut down their own hotspots or leave the debate. At least one photo, taken by Kenneth Vogel of Politico, showed a handheld device that was being used to scan for and locate “rogue” Wi-Fi networks.

To be clear, there’s no evidence that Hofstra, or anyone working on Hofstra’s behalf, was actively blocking radio frequencies, as has been the case in other related circumstances that have drawn the ire of the FCC.

Earlier, Commissioner Jessica Rosenworcel tweeted, saying that something was “not right” with what Hofstra did. She cited an August 2015 order from the FCC, forcing a company called Smart City to no longer engage in Wi-Fi blocking and to pay $750,000.

Hofstra University has not responded to Ars’ request for comment.

UPDATE 4:26pm ET: Karla Schuster, a spokeswoman for Hofstra University, wrote to Ars with this statement:

The Commission on Presidential Debates sets the criteria for services and requires that a completely separate network from the University’s network be built to support the media and journalists. This is necessary due to the volume of Wi-Fi activity and the need to avoid interference. The Rate Card fee of $200 for Wi-Fi access is to help defray the costs and the charge for the service does not cover the cost of the buildout. For Wi-Fi to perform optimally the system must be tuned with each access point and antenna. When other Wi-Fi access points are placed within the environment the result is poorer service for all. To avoid unauthorized access points that could interfere, anyone who has a device that emits RF frequency must register the device. Whenever a RF-emitting device was located, the technician notified the individual to visit the RF desk located in the Hall. The CPD RF engineer would determine if the device could broadcast without interference.

Ars has also contacted the Commission on Presidential Debates, which did not immediately respond.
