During the two-week delay in deploying new 5G service, safety experts determined that 5G interference with the aircraft’s radio altimeter could prevent engine and braking systems from transitioning to landing mode , which could prevent an aircraft from stopping on the runway.

Almost 40 other countries across Europe and Asia use the 5G C-band without any reported effects on radio altimeters that operate in the same internationally designated 4.2-4.4 GHz band , according to the US wireless trade body CTIA.20 Oca 2022

The FAA warned that the new 5G technology could interfere with instruments such as altimeters , which measure how far above the ground an airplane is travelling. Altimeters operate in the 4.2-4.4 GHz range and the concern is that the auctioned frequencies sit too close to this range.

“Wireless carriers in nearly 40 countries throughout Europe and Asia now use the C band for 5G , with no reported effects on radio altimeters that operate in the same internationally designated 4.2-4.4 GHz band,” CTIA, a U.S. wireless trade group, said in a filing with the Federal Communications Commission.

The FAA has issued several airworthiness directives and regulatory policy updates in recent months focused on preventing signals from 5G C-Band towers causing performance issues for aircraft radio altimeters , especially during approaches and landings in low visibility at airports located closest to the towers.4 Şub 2022

C-Band 5G: Everything you need to know More specifically, C-Band refers to radio frequency bands between 4 and 8GHz , according to the Institute of Electrical and Electronics Engineers (IEEE) — although in the case of the US, the FCC designates the range as between 3.7 and 4.2GHz.

Radar altimeter interference from 5G signals can take the form of loss of radar altitude information or, worse, incorrect radar altitude information unknowingly being generated . … This is in addition to radio altimeter use for autoland and in Category (CAT) II/III and Required Navigation Performance (RNP) AR approaches.
