New Delhi: The Indian government has expressed concerns over the possible interference of 5G signals, specifically in the C-band spectrum, with aircraft radio altimeters. Minister of State for Civil Aviation VK Singh informed the Lok Sabha that while no specific study on the impact of 5G on airline services has been conducted, a review by the Directorate General of Civil Aviation (DGCA) suggests a likelihood of interference.
The DGCA’s examination focused on potential risks during the launch of 5G in the C-band spectrum, revealing a potential impact on the functioning of aircraft radio altimeters. Singh noted that manufacturers are working on modified radio altimeters to reduce interference.
Globally, and in India, mitigation measures have been mandated. Telecommunication service providers are advised to establish safety zones, restrict power levels of C-Band 5G near airports, and adjust 5G base station tilts to prevent interference with altimeters.
Responding to queries about government studies on 5G’s effects on airlines, Singh clarified that as India is not the state of design or manufacture for aircraft, the DGCA lacks the necessary design details. Nonetheless, the review of international actions during 5G launches highlighted potential risks, especially during landings, jeopardising safe aircraft operations.
