DoT has advised telecom carriers not to deploy any 5G base stations in the 3,300-3,670 MHz band within 2.1 km of runways at any Indian airports.

The Department of Telecommunications (DoT) has advised telecom carriers not to deploy any 5G base stations in the 3,300-3,670 MHz band within 2.1 kilometres of runways at any Indian airports.

DoT in a letter wrote “The telecom service providers (TSPs) are instructed that no 5G/IMT base stations should be installed in the region 2,100 metres from both ends of the runway and 910 metres from the centre line of the runway of Indian Airports.”

“The maximum power of the base station, node, or repeater put in the periphery of 540 metres around the region shall be limited to 58 dBm/MHz in the 3,300-3,670 MHz band,” the letter continued.

In light of the safety concerns for aircraft operations, Ministry of Civil Aviation has issued a buffer and safety zone drawing and has urged telecom providers to ensure mitigation measures when adopting C-band 5G spectrum in and near airport locations.

According to a letter from the Department of Telecommunications to telecom operators, there shall be no 5G/International Mobile Telecommunications (IMT) base stations in the 3300-3570 MHz band at Indian airports located 2,100 metres from both ends of the runway and 910 metres from the centre line of the runway (C-band 5G).

The letter further stated “Ensure that 5G base stations are tilted downward to the degree that 5G emissions do not interfere with radio altimeters.”

In several countries, the most regularly tested and implemented 5G frequency is n78 (3500 MHz), sometimes known as the 3.5 GHz 5G band or C-band 5G.
