Radio Interference Investigation


ComReg’s Spectrum Compliance section investigates cases of radio interference. Interference can affect any radio service, including but not limited to, emergency services, air traffic control, mobile phone services, business radio, microwave links and broadcast services.

Unintentional interference can be caused by incorrectly or poorly installed radio systems and by faulty or non-compliant electrical or electronic equipment. Unlawful devices, such as mobile phone repeaters are a common source of interference. Any electrical or electronic device has the potential to be a source of radio interference given the right circumstances.

Where a member of the public believes that their telephone, broadband or mobile phone service is experiencing radio interference this should be reported to the service provider. If the service provider determines that an external interference issue is occurring it will contact Spectrum Compliance directly by emailing In such cases Spectrum Compliance can only deal with the network operator and updates cannot be provided to third parties or members of the public.

Licensed operators, having had a competent person (e.g. a radio installer/supplier) check their own system for faults, may report cases of radio interference to Spectrum Compliance directly by emailing

Where a member of the public is experiencing disruption to Saorview or satellite television reception, a television reception system installer should check the installation for faults. System faults such as damaged cables & aerials are common sources of disruption to reception. Should it be determined that the disruption is caused by external interference, this should then be reported to Spectrum Compliance directly by emailing

Please note that ComReg does not charge a fee for investigations of suspected interference.
