Mobile Generations – 1G,2G,3G,4G,5G: Evolution of Wireless Mobile Technology
Mobile phone technology has been evolving from the very first generation 1G to the 5G. Recently telecommunication companies in the Europe, America and Australia are experimenting the 5G technology. We will soon able to use 5G technology. There will be massive incremental in the speed of the internet. Upcoming next generation 5G speed will be between 10 to 20 Gbps.
Let’s see the evolution of wireless technology.
1G refers to the first generation of wireless mobile technology. This technology is analogue based which was introduced in the 1980s. Later it was replaced by 2G.
2G system is the evolution and major breakthrough in the wireless communication. In 2G phone conversations were digitally encrypted. It also introduced the data services in the mobile. SMS (Short messaging system) was also the boon of 2G. Still, many countries use 2G based GSM technology.
3G introduced the mobile broadband. It was in 3G data and voice call could be used simultaneously. 3G provides up to the 7.5Mbps speed of internet in HSPDA technology. Whereas in UMTS data 384 Kbps.
4G also refers as LTE (Long Term Evolution) provides the all the feature and services of 3G. In addition to that, it gives mobile broadband internet access. Its service includes video telephony, HD mobile TV, 3D television, video conferencing and so on. This is present wireless technology. Many countries in the world including India, Nepal, and many countries in Africa just started the 4G deployment recently. Data Speeds of LTE-Advanced during the peak download is up to 1000 Mbps and Upload is up to 500 Mbps.
5G is next generation wireless mobile technology. It is currently under the trial. It will provide ultra speed mobile broadband internet. Its speed will be up to 10Gbps to 20Gbps. According to the International Telecommunication Union (ITU), 5G technology will have it speeds up to 20Gbps. However, other different forums are stating different speed. It is still under the testing and trial.
Comment below which technology are you using now and what’s the speed?
