With the launch of 3G services, everybody wants to know about these services. How can they change the way that we communicate? 3G (third generation) services not only allow us to access Internet at high speed but they also enable us to enjoy multimedia services, the ability to view videos on our mobile phone.
If we compare with a dial-up Internet connection, it typically offers about 56 kbps speed. Whereas a 3G connection will offer you speed of 3.1 megabits per second (mbps) or more. 3G network an ITU specification for third generation of mobile communications technology- was first introduced by Japan on a large commercial scale. At present, there are around 60 3G networks across 25 countries.
3G technologies comprise of three technologies WAP, GPRS and EDGE. WAP (Wireless Application Protocol), an open international standard, is usually used for small mobiles. After the launch of WAP, GPRS was developed offering the speed around 56-114 kbps. It allows the user to avail services like GPRS, PTT, instant messaging/chat facilities, MMS etc. However, it fails to stream live videos more efficiently. After that, EDGE, also termed as 2.75G network, comes in the field of mobile communication. It can carry a bandwidth of up to 236.8 kbps.
With 3G Services, an individual can enjoy a lot of features such as:
* Phone calls/fax
* Send/receive large email messages
* High-speed Web
* Global roaming
* Navigation/maps
* TV streaming
* Videoconferencing
* Electronic agenda meeting reminder
Difference between 2G Vs. 3G Networks-
With HSDPA, 3G technology sends data many times faster as compared to 2G network. Therefore, if youre planning to purchase a new mobile, you should for HSDPA compatibility as it will provide you the data speed on the move. That means, in 3G coverage areas, you can send and receive video content along with audio, graphics and text. However, the speed of network depends upon mobile used, number of users using 3G network simultaneously, coverage and network traffic.
