The company responsible for the interference was issued a forfeiture order by the FCC enforcement bureau in the amount of $10,000. While the company used equipment that had been previously certified under the FCC rules for UNII operation, the equipment causing interference was operating on frequencies that it had not been approved for. Moreover, if the transmitters would be considered non-UNII devices and subject to section 15.407(2) of the FCC rules, then the power allowed would have been limited to ¼ Watt in that particular frequency band, however, the devices in question were designed to operating in excess of three times that level.
