Answer: 5G high bands (mmWave, also referred to as FR2) are found in the range of 24GHz to 40GHz. They deliver large quantities of spectrum and capacity over the shortest distances

Due to the different speeds of P and S waves, a single seismometers can determine the distance to an earthquake. So, for a single station, the localization is any point on a circle around the station. With 2 stations, you'll have two circles that intersect at two points. The 3rd station is needed in order to determine which of the 2 points is the actual earthquake.</span>
?? it should be radio waves but i guess the next best thing is microwaves
Please provide photos for your question.
