5G band sufficiently spaced out from those used for radio altimeter in aircraft: Govt

The frequency band of 3300-3670 MHz identified for 5G technology in India is sufficiently spaced out from the 4200-4400 MHz band, used for radio altimeter in planes, and it is "very unlikely" to cause any interference in radio altimeter communications, the government said on Wednesday.

Some media reports have been published regarding observations of US Federal Aviation Administration (FAA) on possible interference by 5G technology with radio altimeter used in aircraft, Minister of State for Communications Devusinh Chauhan said in a written reply in Lok Sabha.

Further, Chauhan said the frequency band identified for 5G technology is 3300-3670 MHz, among others, which is sufficiently spaced out from the frequency band 4200-4400 MHz, used for radio altimeter in aircraft and "it is very unlikely to cause any interference with the operation of radio altimeters".

He was responding to a query on whether the government has studied the potential risks to flight safety likely to be caused by the rollout of 5G services.

"No study has been carried out in this regard, as the frequency bands opened in the country for IMT, including 5G technology, are as per the techno-regulatory conditions specified by the International Telecommunication Union and National Frequency Allocation Plan (NFAP)-2018," Chauhan said.

On whether the spectrum to be allocated for 5G services coincide with the altimeter spectrum, the minister said, "no".
