Airlines cancelling flights to US over 5G US telcos have 5G over the wrong frequencies Major international airlines are canceling flights to the United States over aviation industry fears that 5G technology could interfere with crucial onboard instruments. This might seem strange as 5G is being rolled out in the EU without any problems. But US Mobile phone companies are rolling out 5G service in a spectrum of radio waves with frequencies between 3.7 and 3.98 GHz. The companies paid the US government $81 billion in 2021 for the right to use those frequencies, known as the C-Band. But in Europe, 5G services use the slower 3.4 to 3.8 GHz range of spectrum. The US 5G service is too close to the spectrum used by radar altimeters, which is between 4.2 and 4.4 GHz. Europe does not face the same risk, according to the industry, because there is a much larger buffer between the spectrum used by radar altimeters and 5G. There are other differences in how 5G is being rolled out, according to the US Federal Aviation Administration (FAA). Other countries are using lower power levels, restricting the placement of 5G antennas near airfields and requiring them to be tilted downward to limit potential interference with aircraft. https://fudzilla.com/news/network/54...-to-us-over-5g |
