Boeing faces a setback as its 777 and 787 planes used by airlines worldwide are particularly susceptible to the new 5G network signals as the Federal Aviation Administration (FAA) announced safety concerns.

The FAA said the new 5G signals could interfere with the Boeing 787's and 777's airplanes systems using radio altimeters, which indicate how far a plane is off the ground while in the air, according to a statement Friday.

Altimeters data are used in several systems such as for engines, flight controls, traffic alert, collision avoidance, ground proximity warning, autopilot systems, and detecting dangerous wind shears.

Airlines are concerned because altimeters operate in the 4.2-4.4 GHz range, and the 5G frequencies would operate too close to the same range and affect airplane instruments, Reuters reported.
