short notes on 2g,3g,4g service
Answers
Answer:
2g service :-
2G technologies enabled the various networks to provide services such as text messages, picture messages, and MMS (multimedia messages). With General Packet Radio Service (GPRS), 2G offers a theoretical maximum transfer speed of 40 kbit/s.
3g service :-
To sum it all up, 3G network speeds were great for voice and data, while having some of the fastest download speeds available today. 4G LTE offers voice and data just like 3G, however, the download speeds are known to be almost twice as fast and also reach much further than the earlier 3G.
4g service :-
It's more reliable, it works out cheaper for heavy users, speeds are pretty good most of the time, and it's likely you'll get unlimited downloads too. For general internet use there's not much better, provided you can get decent speeds.
