How the Internet Has Changed(The Revolution)




 How the Internet Has Changed(The Revolution): Comprehend the technology behind your smartphone. Identifying the strengths of the underlying technology of a smartphone is simple as long as you understand THE MEANING OF 1G, 2G, 3G, 4G, AND 5G. Here ‘G’ means generation. 1G refers to the first generation of wireless cellular technology, 2G refers to the second generation of wireless cellular technology, and so on. As you might expect, the ensuing generation is faster and contains improved or new features. Technology beneath cell phones and other peripherals has evolved over several decades. Starting with revolutionary 1G all the way to the 4G of today and 5G of the near future. Nowadays most of the carriers support 3G and 4G cellular technology. So, what has really changed?


In the early 1980s, it started its journey. A new generation wireless mobile telecommunication technology has been released roughly every 10 years. The new generation has different speeds and features that improved on the previous generation. Upcoming, the next generation is 5G, Which is scheduled to launch in 2020


1> 1G(Voice only): Remember analog phones? Cell phones began with 1G technology in the 1980’’s. 1G is the first generation of wireless cellular technology which supports voice calls only. The maximum speed of 1G technology is 2.4 kbps.



2> 2G (SMS, MMS): Cell phones received a major upgrade when the technology went from 1G to 2G. In Finland, in1991. This loop took place on GSM networks and effectively took cell phones from analog to digital communications. With launching 2G, it introduced call and text encryption along with data service (SMS, Picture Msg, MMS). The maximum speed of 2G with GPRS is 50Kbps.



3> 3G(Video calling, mobile Internet): The introduction of the Third generation (3G) in 1988. It was better for video calling and mobile internet access. Letter 3G evolved into the much faster 3.5G and 3.7G as more features were introduced before 4G. This was a big revolution in terms of technological advancement for network and data transmission. It had a speed potential of up to 2 Mbps. 3G enabled smartphones to provide faster communication, send/receive large files, Fast web browsing, video streaming/download  3G was widely based on CDMA2000 (Code-division multiple access) technologies.



4> 4G (The current standard): The fourth generation of networking was launched in 2008. It supports mobile web access like 3G does and also gaming service, HD mobile TV, video conferencing features that require high speed. The maximum speed of 4G in a moving condition is 100 Mbps. Soon after 4G, 4G LTE(Long Term Evolution) was introduced. 4G LTE was a complete redesign and lightening of 3G network architecture, resulting in a Noticeable reduction in transfer dormancy and thus, progressive efficiency and speeds on the Network.




5> 5G (Coming soon): 5G is a not yet implemented wireless technology that's intended to improve on 4G. 5G promises significantly faster data rates, higher connection density, much lower latency with energy-saving and other improvements. The expected abstract speed of a 5G connection is up to 20 Gbps.
