As concerns continue to swirl around the potential interference between 5G technology in the C-band and aircraft instruments, the Cellular Operators Association of India (COAI) is calling for a practical solution. COAI is suggesting that airlines conduct simulated flights to determine if there’s any validity to these concerns, rather than halting the 5G deployment near airports. Let’s delve into the details.
The Conundrum of 5G and Aviation
For over a year, the deployment of 5G near airports has been a contentious issue. The primary concern is the potential interference of 5G signals, specifically in the C-band (3.3-3.67 GHz in India), with critical aircraft instruments, particularly Altimeters. Altimeters are vital for gauging the distance between aircraft and the ground, and any disruption in their readings could jeopardize flight safety.
The contention arises from the fact that Altimeters and 5G networks use different frequency bands within the C-band. Altimeters operate in the 4200-4400 MHz band, while 5G is deployed within the 3300-3670 MHz band. The lower end of the C-band is what’s allocated for 5G, posing the question of whether these frequencies could indeed interfere with Altimeters operating in a higher spectrum range.
COAI’s Proposal: Testing the Theoretical
In response to this impasse, COAI proposes a practical solution. The industry body suggests that airlines conduct simulated flights to assess whether 5G deployments genuinely interfere with Altimeter operations. If the simulated flights reveal no issues, it could pave the way for the safe deployment of 5G near airports.
COAI also draws attention to the fact that European countries have deployed 5G within the C-band near airports without encountering any problems with aviation interference. By urging airlines to conduct these tests, COAI aims to address the concerns of various stakeholders, including travelers, and residents living near the 137 airports across India.
Closing the 5G-Aviation Gap
The call for simulated flights to ascertain the compatibility of 5G and aviation instruments presents a potential solution to a long-standing issue. By subjecting these concerns to practical tests, it could help expedite the deployment of 5G near airports while ensuring the safety and peace of mind of all those involved.
