What is meant by 1G,2G and 3G?
Answers
Answer:
G stands for Generation.
Explanation:
1G: Voice Only
Remember analog phones back in the day? Cell phones began with 1G technology in the 1980s. 1G is the first generation of wireless cellular technology. 1G supports voice only calls.
2G: SMS and MMS
Cell phones received their first major upgrade when their technology went from 1G to 2G. This leap took place in Finland in 1991 on GSM networks and effectively took cell phones from analog to digital communications.
The 2G telephone technology introduced call and text encryption, along with data services such as SMS, picture messages, and MMS.
3G: More Data, Video Calling, and Mobile Internet
The introduction of 3G networks in 1998 ushered in faster data-transmission speeds, so you could use your cell phone in more data-demanding ways such as for video calling and mobile internet access. The term "mobile broadband" was first applied to 3G cellular technology.
The maximum speed of 3G is estimated to be around 2 Mbps for non-moving devices and 384 Kbps in moving vehicles.
4G: The Current Standard
The fourth generation of networking, which was released in 2008, is 4G. It supports mobile web access like 3G does and also gaming services, HD mobile TV, video conferencing, 3D TV, and other features that demand high speeds.
The max speed of a 4G network when the device is moving is 100 Mbps. The speed is 1 Gbps for low-mobility communication such as when the caller is stationary or walking.
