3G TECHNOLOGY

Definition of 3G:

3G is the third generation of wireless technologies. like high-speed transmission, advanced multimedia access and global roaming. 3G is mostly used with mobile phones and handsets as a means to connect the phone to the Internet.


3G Technical Specifications:

The transfer rate for 3G networks is between 128 and 144 kbps for devices that are moving fast and 384 kbps for slow ones. For fixed wireless LANs, the speed goes beyond 2 Mbps.
3G is a set of technologies and standards that include W-CDMA, WLAN and cellular radio, among others.


What is Required for Using 3G?:

The first thing you require is a device that is 3G compatible. This is where the name 3G phone comes from - a phone that has 3G functionality; nothing to do with the number of cameras or the memory it has. An example is the iPhone 3G.
3G phones commonly have two cameras since the technology allows the user to have video calls, for which a user-facing camera is required for capturing him/her.

What Does 3G Cost?

3G is not very cheap, but it is worthwhile for users that need connectivity on the move. Some providers offer it within a somewhat costly package, but most of them have plans where the user pays for the amount of data transferred.

3G and Voice:

Wireless technologies are a way for mobile users to make free or cheap calls worldwide and save a lot of money due to the latest telephony applications and services. 3G networks have the advantage of being available on the move, unlike Wi-Fi, which is limited to a few meters around the emitting router. So, a user with a 3G phone and a 3G data plan is well-equipped for making free mobile calls. She will only have to download one of the free applications and install on her mobile phone and start making calls.
