Difference between 3G, 3GS and 4G

It seems that no sooner has one technology come up than another one appears over the horizon threatening to make the previous one obsolete. Such is the case in the fast-paced and intensely competitive world of mobile phone technology and the decision that so many people now face is whether to go with 3G, 3GS or 4G. The decision isn't always an easy one to make, particularly since sheer power and features aren't the only factors that come into play. Let's look at some of the more telling points of each and why it may or may not be the best choice for you.

Profile

  • 3G is the third incarnation of a line of wireless technologies. It offers various features including fast data transmission, advanced multimedia capabilities and global roaming.
  • 3GS is a step up from the 3G spec, with the "S" used to denote "speed". 3GS devices are expected to run twice as fast as 3G devices.
  • 4G is the latest incarnation in the line and it offers even more features such as true multitasking, and even faster data transfer rates.

Features

3G is only one in the line of wireless systems belonging to the IMT-2000 or International Mobile Communications 2000 standard, which began to be implemented in the early 1990s. Among other advantages, 3G offers faster data exchange than the previous systems. 3G equipped phones also usually have two cameras onboard to facilitate video communication.

The 3GS system offers a number of improvements and enhancements over 3G, with better camera technology and the ability to shoot video among the more attractive ones. Interestingly enough, most 3G devices did not allow this feature, although it was possible with the use of 3rd party software.

As for the 4G, multitasking is its biggest claim to fame. This allows users to perform a variety of tasks without having to focus in each application in turn. Many 4G models also feature hi-definition Camera, Camcorder, and audio features, along with a full featured GPS.

Benefits And Advantages

As mentioned previously, 3G offers a significant speed boost over previous technologies. In addition, the system also allows for better audio and video streaming, and even video-conferencing is supported. Users can also browse at much higher speeds than previously possible. 3GS adds even more speed to the mix, and it is about twice as fast as most 3G units.

4G for its part allows the transmission of larger packets of data, with lower bit error rates, which means increased data throughout all around.

Summary

3G

  • Communication standard that includes W-CDMA, WLAN, cellular radio and many more
  • Offers a transfer rate of 128 to 144 kbps for "slow" devices, and 384 kbps for "fast" ones
  • Offers a fixed wireless LAN speed of more than 2 Mbps
  • Requires a 3G compatible device such as a mobile phone
  • Often comes with two cameras to facilitate video calls

3GS

  • Up to twice as fast as 3G devices
  • Very good 3 megapixel camera on board, with auto-focus features
  • Can be used to shoot video unlike many 3G models
  • Offers voice control feature
  • Much better battery life

4G

  • Allows transfer of larger data packets with less bit errors
  • Improved data throughput rate
  • Allows faster and more stable access to multimedia and video content on the go
  • Multitasking capability
