According to the U.S. Federal Communications Commission (FCC) notification, it has received a complaint from T-Mobile with regards to “interference to its 700 MHz LTE network in Brooklyn, New York” during last year. The commission’s agents confirmed that the “radio emissions in the 700 MHz band were emanating from…an antminer s5 bitcoin miner.”
In the notification, the FCC states that ‘the device was generating spurious emissions on frequencies assigned to T-Mobile’s broadband network and causing harmful interference”.
The commission issued a warning to the owner of the mining hardware Victor Rosario. He was not allowed to continue the operation of the device because it caused harmful interference. A violation of the Federal laws cited above and could subject the operator to severe penalties, including, but not limited to, substantial monetary fines, in rem arrest action to seize the offending radio equipment, and criminal sanctions including imprisonment.
According to the FCC, it has not made a determination as to whether or not other Antminer S5s produce disruptive emissions in the 700 MHz band. It also emphasizes that it does not wish to suggest that all Antminer S5 devices are noncompliant but it aware that devices can be modified in a manner that creates harmful interference.
