1G, 2G, 3G, 4G, has something in common i.e. the ‘G’ which stands for Generation which straightly signifies the tenure or generation which is 1st generation, 2nd generation and so on.
1G i.e. 1st generation is the oldest one and was introduced when the first phones were made. This phones were bulky and bigger in size as now.
2G which is the 2nd generation of network transmission. Some new features were added apart from making calls like text messaging(SMS).
3G is the third generation which was the first wireless networking system. This is the system that is being currently used in smartphones which allows us to browse through the Internet, stream and download videos, emails and lots of other features making human life much simpler. 3G is capable of producing network speed up to 2 Megabytes per Second(Mbps).
4G is such a network developed which is far beyond 3G and can handle speeds from 100 Mbps to 1 Gigabytes per Second(Gbps). It is better than the above networks as has good speed comes good encryption, so this network is more protective against the hackers or phishers. This network is currently very popular in India as the Reliance Telecom Services launched its new network “JIO” which made it most used network in India. Also a new term is currently added to it i.e. “VoLTE” which means ‘Voice over Long-Term Evolution’. VoLTE has up to three times more voice and data capacity than 3G and up to six times more than 2G.
5G, which is kind of new to everyone and is not officially yet started in many parts of the world. As by a guess this network is called to break all the speed records and change the world upside down and bring an evolution in Mobile Network history.
