Can someone help me understand this better? What is "very close" to 23.8-GHz frequencies? I don't know which bands 5G operates on, but it seems [1] that the closest they get, at least in the US, is ~27 GHz. If the FCC is auctioning 3000 licenses for the 24 GHz space, is that the space that can potentially interfere more? Can 5G operate on just any frequencies, then?

- TrueDuality 8y agoThe carrier signal of a new technology could potentially use any frequency that isn't already in use. A lot of the frequency spectrum is already accounted for and generally parts of the spectrum that are important to scientific research are internationally protected (Such as the resonant frequency of hydrogen which is used extensively in radio astronomy). That being said it is more technically difficult to go "up" in frequency. Lower frequencies have less bandwidth, but are easier to generate, can go through physical objects better and for longer distances. This fight to me looks like the industry wants to use a cheaper frequency that meets their minimum technical goals (in terms of development costs not necessarily licensing costs) science and other applications be damned.
