5 Key Differences Between mmWave and sub-6GHz
2020-11-02
5G is the first system where frequencies higher than 6 GHz are taken into account. The motivation behind new spectrum portions is the mentioned need for offering throughput of gigabit/s and more. The game is worth playing since, in the mmWave, Gigahertz spectrum bandwidths can be applied. But one may pose the question: if the price is so exciting then why nobody used mmWaves previously in cellular systems?
