The US Federal Communications Commission (FCC) has slapped a $144,000 fine on Intel for using unauthorised devices without getting clearance from the agency.
The FCC fined the tech giant after an investigation that found that some of the devices used by Intel for evaluation are in violation of the agency's norm.
The chip maker is said to have used the devices in residential areas for testing and evaluation without getting consent from FCC and also displayed a prototype device at a trade show without proper labelling.
The chip maker had notified the FCC in 2012 that the use of the devices might be in violation of FCC's rules.
Later, Intel identified the prototype models and admitted that it is an 'inadvertent deviation from standard practices' by the company.
The FCC has also asked Intel to adopt a three-year compliance plan.
An Intel spokesperson told the Wall Street Journal: "We are creating a program that gives the FCC confidence that we are taking steps to help insure future compliance with the rules. Intel is pleased to put this matter behind us."
