Why 5G Rollout Is Causing Aviation Problems In The United States But Not In Europe
All promised him to be very happy with the deployment of his new in the United States 5G network: the so-called C-band promised to overcome the limitations of the mmWave band, but its implementation there has created real chaos By Possible disruption with aircraft altimeters,
the funny thing is that Europe has never had such a problem, and the deployment of these networks in that band has gone smoothly. What makes a deployment in Europe different from a deployment in the United States? Let’s talk about frequencies.
your frequencies are higher than mine
Uses 5G technology different frequency bands, but the one that promised more speed was the millimeter band, mmWave. also known as,
The problem with this technology is that its coverage is often limited to very limited areas, and That’s where the C-band comes in, notwithstanding less able In consumption, it provides greater coverage and allows wider deployment of these high-speed mobile networks.
However, the deployment of this band has varied in the United States and Europe, and the main focus lies in the frequency range used: while Frequencies between 3.7 and 3.98 GHz have been used in the US.In the Europa, some of the lower and slower frequencies, ranging from 3.4 to 3.8 GHz, have been used.
That’s where the problem arises: the altitude of aircraft such as the Boeing 777 that can be obstructed by these signals Use a frequency range from 4.2 to 4.4 GHz,
The US C-band is very close to that frequency range, and This is what caused alarm among airlines, which threatened to cancel their flights if the deployment continued. Operators such as AT&T and Verizon limited deployment, for example to now include calls.buffer zone“(“buffer zone”) in which the C-band is not operational.
That fear doesn’t exist in Europe. The European Union Aviation Safety Agency (EASA) indicated on CNN that “we have received technical data from European manufacturers”. Do not produce conclusive evidence that gives us immediate security concerns Now”.
Countries like France have gone even further, and in their deployment near airports They have intentionally hooked up towers with 5G antennas To limit their possible interference with the aircraft.
They did it as a preventive measure, and they haven’t had a problem With deployment of 5G network in C-band. It remains to be seen how carriers like Verizon or AT&T ultimately address the problem, if at all.
