Difference between 3G and 4G

Difference between 3G and 4G

Technology is getting so advanced day by day that we can’t measure up its existence. In the tunnel of technology 3G and 4G are at the peak on the human mind. Now the question arises in the mind that whether 3G is superior or 4G. N0w what are they? And how they functions will be knowing all these things in this article. 3g and 4g are the high standards for the mobile communication. The standards refers to the air waves of the transmission of information. This post will reveal the difference between 3G and 4G.

3G vs 4G

An overview of these two jaw breaking technologies! When it comes to 3g or Third generation it was launched in japan in 2001. The most wireless networks carriers in the US is 3G. These are improved networks and majorly designed as an improved versions of 2G networks. These are offering high speeds for data transfer. The improvement that 4G offers over 3G is less existent in people’s mind. When we look into the technologies’ eye there is an analogy of standard which is compared to Hi-Def TV to describe the difference between these two technologies.

The speed of 4G vs 3G a striking question? How much faster 4G when compared to 3G is definitely strikes the mind when we see something new and full of energy underlying. The speed of 3G network is mainly depend on how it is implemented. According to the analyst and the scientists the upgrading of the 4G networks allows and offer data transmission, speed up to 4 times faster than 3G networks. 3G provides space 3.1 Mbps with an average speed range 0.5 to 1.5 Mbps. Its peak download rate is 100 Mbps. On the other hand when it comes to 4G Australian scientists claims that it can give speed up to 40 Mbps but it is heard that its range lies from 100 to 300 Mbps. Its peak download rate is 1 Gbps.

What are the switching technique and network architecture that they use? When it comes to 3G technology it uses the technique of packet switching. On the other hand 4G is also using the same technique but it is using another technique of message switching which makes its use more significant and useful. As far as the architecture is concerned 3G is designed upon wide area cell based network whereas 4G is using the architecture of integration of LAN and WAN.

Design principle and applications: Both the technologies were designed primarily for voice communication rather than data transformation. As far as 4G design and application is concerned 4G is designed not for the voice communication but for the data transmission. In this way 4G offers faster access to data using mobile phones. For example when we watch streaming video that streaming video will work better with 4G because there will be less shuttering and high resolution of screen. Also when it comes to the multiplayer and online games it will work faster and provide and high data transmission offered by 4G.

Forward error correction and frequency band these two are using? 3G uses turbo codes for their error correction. On the other hand, 4G uses concatenated codes for error correction. Finally when we talk about frequency band 3G is lower in frequency that varies from 1.8 to 2.5 GHz whereas 4G is leading up and on the front-line giving the frequency band which varies from 2 to 8 GHz.

By concluding the whole discussion we can say that 3G is still on the way of improvement though 4G is on the front line to break its existence. 4G is popular because it is sharing a large number of towers which 3G is not. Both are good at their level but people go for what they are getting day by day.
