GS Paper - 3 (Information and Communication Technology)

Ahead of the mega 5G rollout in the US, major airlines like Emirates, Air India, ANA and Japan Airlines have announced to cancel some flights over concerns that it could potentially interfere with some instruments and may put flyers' safety at risk.

Why is that a problem?

  1. The US Federal Aviation Administration (FAA) has warned that the new 5G technology could interfere with instruments such as altimeters, which measure how far above the ground an airplane is traveling.
  2. Altimeters operate in the 4.2-4.4 GHz range and the concern is that the auctioned frequencies sit too close to this range.
  3. In addition to altitude, altimeter readouts are also used to facilitate automated landings and to help detect dangerous currents called wind shear.
  4. The higher the frequency in the spectrum, the faster the service; So in order to get full value from 5G, operators want to operate at higher frequencies.
  5. Some of the C band spectrum auctioned had been used for satellite radio but the transition to 5G means there will be much more traffic.
