DoT resolves 5G coexistence with radio altimeter, begins research on CBRS: Official, ET Telecom

NEW DELHI: The Department of Telecommunications (DoT) is working to resolve the coexistence issue of fifth generation or 5G networks and aircraft radio altimeters, a senior official of the ministry has said, adding that the ministry will soon open up radio altimeters to its citizens. He added that he will begin research into this. Broadband Radio Service (CBRS) Band.

“We are unable to provide 5G services near airports and we are working to resolve the issue. CBRS is under active consideration with the DoT and we will soon start looking into opening up the CBRS spectrum,” he said. Gunjan Dave, Member (Technical), Ministry of Telecommunications, said this at an industry conference organized by ITU-APT Foundation (IAFI). .

Dave also said that spectrum allocation is a major challenge and requires continued consideration of how to effectively share spectrum to shape future technology adoption.

ET in its Feb. 20 issue that residents around the country’s 124 airports could be able to use fifth-generation services from January 1 next year, and the government plans to replace all older aircraft’s radio altimeters by the end of the year. It has been determined that it needs to be replaced or upgraded by. 2024.

Until now, 5G deployments have been prohibited in and around airports due to concerns that the 3300-3670MHz spectrum could interfere with aircraft radio altimeters. Telecom operators in India are rolling out 5G networks using the 3300-3670MHz band.

In particular, existing altimeters operate in the 4200-4400 MHz band, approximately 500 MHz away from the 5G operating frequency.

Gulab Chand, Joint Radio Advisor, Radio Programming and Coordination Department, Ministry of Telecommunications, said in a statement by IAFI that India has succeeded in establishing a charter for the 6 GHz band and is a national success in enhancing the ease of doing business. emphasized.

Kumar N. Sivarajan, Chief Technology Officer (CTO) of Tejas Networks, an indigenous telecommunications equipment manufacturer, said that the 2023 Global Wireless Initiative will help drive ubiquitous communications to end the connectivity gap that currently remains in areas such as aviation. He emphasized the role of the Correspondence Conference (WRC) initiative.

Sivarajan said these are “exciting and challenging times” as the need for equipment to support rapidly changing service technology continues to grow, according to an IAFI statement.

IAFI President Bharat Bhatia, in a statement, noted the international importance of WRC-23’s collective efforts to ensure efficient and fair allocation of spectrum.
