Read moreWhat are the differences amongst 2G 3G 4G and 5G networks?
4G is more spectrally efficient than 3G, just as 5G is more spectrally efficient than 4G . Each generation delivers more data per hertz than the previous one. 3G works at frequencies up to 2.1Gigahertz, 4G up to 2.5Gigahertz and 5G can be up to 95 Gigahertz. That is why there is a lot of hype around 5G.
