WebAs discussed in Chapter 23, 5G radio access should cover a very wide range of frequencies, from below 1 GHz up to at least several 10 GHz, and possibly as high as 70–80 GHz. For the lower part of the spectrum, perhaps as high as 5 GHz, a subcarrier spacing of the same order as LTE is sufficient. WebApr 25, 2024 · For the lower range of carrier frequencies, from below 1 GHz up to a few GHz, the cell sizes can be relatively large and a cyclic prefix capable of handling the delay spread expected in these type of deployments, a couple of microseconds, is necessary.
