1G to 5G evolution

1G, 2G, 3G, 4G and 5G are the five generations of mobile networks where G stands for Generation, and the number denotes the generation number . 5G is the latest generation, whereas 1G networks are now obsolete. The cellular technologies GSM, UMTS, LTE and NR enable 2G, 3G, 4G and 5G, respectively. Term. Stands for.3 Mar 2020

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.

5G is shorthand for fifth generation, and it promises cellphone speeds as much as 100 times faster than the norm today, 4G LTE . Gigabit internet (so named because data are transmitted at up to 1 gigabit or 1,000 megabits per second) also promises that kind of speed — about double that of the fastest cable internet.
