Edinburgh, August 24, 2022. – The International Telecommunication Union (ITU) has issued a warning to its 193 member states about harmful interference such as blocking, jamming or serious degradation of services based on radio waves.

The ITU defines harmful interference as a radio system receiving unwanted energy to an extent that interferes with the operation of a radio navigation service. Furthermore, such interference may seriously degrade, impede or repeatedly interrupt any radiocommunication service operating in accordance with the Radio Regulations. This poses a threat to critical infrastructure such as commercial aviation, power distribution and satellite navigation systems, according to the ITU.

ITU claims to have received 329 reports of harmful interference or violations of the Radio Regulations between 1 February 2021 and 31 January 2022. Following these incidents, the Union has urged its Member States to take preventive measures.

The ITU suggests that the 193 Member States strengthen the resilience of navigation systems and develop techniques for mitigating loss of service. In addition, they must increase collaboration between radio regulatory, military, aviation and law enforcement authorities. In addition, they are required to strengthen civil-military coordination and maintain conventional navigation infrastructure essential for emergency support.
