Generations of Network 1G, 2G, 3G, 4G, 5G
Generations of Network 1G 2G 3G 4G 5G:
1G is the first-generation of wireless telephone technology, mobile telecommunications. It introduced in 1987 by Telecom known today as Telstra, Australia received its first cellular mobile phone network utilising a 1G analogue system. It is an analogue technology and the phones generally had poor battery life and voice quality was large without much security, and would sometimes experience dropped calls. The maximum speed of 1G is 2.4 Kbps.
Second-generation cellular telecom networks commercially launched on the GSM standard in Finland by Radiolinja in 1991. This technologies enabled the various mobile phone networks to provide services such as text messages, picture messages and MMS (Multimedia Messages).
All text messages sent over 2G digitally encrypted, which allows for the transfer of data in such a way that only the intended receiver can receive and read it. The max speed of 2G with General Packet Radio Service (GPRS) is 50 Kbps or 1 Mbps.
3G is a third-generation wireless technology that allows mobile phones to access the internet from surfing web pages to making video calls and downloading music. These telecommunication networks support services that provide an information transfer rate of at least 200 kbit/s. It finds applications in wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV. 3G standard utilises a new technology called Universal Mobile Telecommunications (UMTS) as its core network architecture. This network combines aspects of the 2G network with some new technology and protocols to deliver a significantly faster data rate.
It is a very different technology as compared to 3G. 4G system provides mobile ultra-broadband Internet access, Conceivable applications. It includes amended mobile web access, IP telephony, Gaming Services, High-Definition Mobile TV, Video Conferencing, 3D Television, and Cloud Computing.
It is a generation currently under development, that’s intended to improve on 4G. 5th generation mobile networks denote the next major phase of mobile telecommunications standards beyond the current 4G/IMT-Advanced standards. It also referred to as beyond 2020 mobile communications technologies. 5G is much faster data rates, higher connection density, and much lower latency. It also includes device-to-device communication, better battery consumption, and improved overall wireless coverage. The max speed of 5G is aimed at being as fast as 40 Gbps, which is over 40 times faster than 4G.
