Advanced imaging technology uses automated target recognition software that eliminates passenger-specific images and instead auto-detects potential threats by indicating their location on a generic outline of a person Sub-6 is the 5G of the present, while mmWave is clearly the 5G of the future. But it isn't quite that simple. It's clear that we'll need to use both Sub-6 and mmWave together eventually.
The millimeter-wave band thus corresponds to a wavelength range of 10 mm at 30 GHz decreasing to 1 mm at 300 GHz. Therefore, switch-mode PAs may not work as efficiently at mm-Wave frequencies as they do at lower RF frequencies. Therefore, mm-Wave PAs are mostly operated in the class A/AB region, which affects PA efficiency. Secondly, losses. Millimeter wave scanners have been in use in many airports since May 2013. The scanner processes an image by using colors to mark out any areas that may require further screening. However, when a green GO sign like the traffic light appears on the screen without an outline or box, it means the passenger is cleared to proceed Due, in part, to radiation exposure concerns, the TSA has been testing millimeter wave machines.
