US Airlines is suspending flights. How the 5g network is interfering with airplanes
The attempt to spread the improved 5g mobile service throughout the United States has been tumultuous. The aviation industry and transportation regulators are concerned about new 5G antennas interfering with a key type of aircraft altimeter that is essential for landing aircraft in bad weather. But mobile operators and regulators have said there is nothing to fear.
Authorities have been in a stalemate for weeks. And it all peaked this week with several major international airlines canceling several flights to the US after regulators, telecom giants and airlines exceeded the deadline to reach an agreement.
Why is this happening in the US and not abroad?
Europe distributed 5G without any impact on aviation, standing in stark contrast to the fury that is taking place in the United States. The difference lies in some key technical details.
Wireless carrier companies in Europe deploy new 5G service in the 3.4 to 3.8 GHz spectrum. The United States is delivering 5G service on a radio wave spectrum with frequencies between 3.7 and 3.98 GHz, which is a faster interval and slightly closer to the spectrum used by radar altimeters, which is between 4.2 and 4.4 GHz.
Other countries are also using other mitigation tactics to prevent interference, such as restricting the placement of 5G antennas near airfields.
