>5G specification includes a variety of frequencies for back haul and end user devices. These frequencies include mm-wave. I'm not denying that 5G specifies frequencies that go into the millimeter wavelengths. What I am saying is that right now the current implementations of 5G in actual use are not going into those frequencies in any widespread fashion. Most installed 5G is using centimeter wavelength frequencies and will likely stay that way for a good while. The specification allows for millimeter wave frequencies, but it's going to be difficult to find them in actual widespread use at the moment.
