Context

• The US Federal Aviation Administration (FAA) has warned that the new 5G technology could interfere with instruments such as altimeters.

About

• An altimeter or an altitude meter is an instrument used to measure the altitude of an object above a fixed level.
• So, in aviation it measures how far above the ground an airplane is travelling.
• In addition to altitude, altimeter readouts are also used to facilitate automated landings and to help detect dangerous currents called wind shear.
• Concern: Altimeters operate in the 4.2-4.4 GHz range and the concern is that the auctioned frequencies sit too close to this range.
