A New York City resident was ordered to turn off his bitcoin miner after the Federal Communications Commission discovered that it was interfering with T-Mobile’s wireless network.

After receiving a complaint from T-Mobile about interference to its 700MHz LTE network in Brooklyn, New York, FCC agents in November 2017 determined that radio emissions in the 700MHz band were coming from the residence of a man named Victor Rosario.

“When the interfering device was turned off the interference ceased,” the FCC’s enforcement bureau told Rosario in a “Notification of Harmful Interference” yesterday. “You identified the device as an Antminer S5 Bitcoin Miner. The device was generating spurious emissions on frequencies assigned to T-Mobile’s broadband network and causing harmful interference.”
