3G Technology
3G is the third generation of wireless technologies. It comes with enhancements over previous 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 or other IP networks in order to make voice and video calls, to download and upload data and to surf the net.
Function
3G is the latest mobile technology and is now the fastest growing host among mobile units and handsets.3G networks operate on technology called High Speed Downlink Packet Access (HSPA). Data is transmitted many times faster than earlier 2G networks. This basically means that in addition to the earlier audio, graphics, and text, you can now send and receive video content too — provided you have a 3G-enabled handset or USB datacard and are in 3G coverage areas.
Higher speed
With 3G technology, you get to enjoy data transmission speed leading up to 2Mbps, considering that you have a phone in stationary mode.In ideal conditions, 3G service provides for download speeds of 14.4 megabits per second. Upload speeds range around 5.8 megabits per second.
3G Coverage
If you have a 3G phone, you’ll see a small symbol on your phone. This symbol is usually a small ‘3G’ sign on the upper left corner of your screen. Depending on the handset, it can also appear as ‘3.5G’ or ‘3G+’ if you are in areas with faster speed coverage.
