Re: They only need smaller cells for higher frequencies

5G is using CP-OFDM modulation instead of OFDMA to resolve that issue, since it is localized in the time domain. It may be using shorter symbols too (I don't know all the details on 5G to be sure) but not NEARLY as short as if it used the same modulation as LTE.
