What is the difference between 3.9g and 4g

Whereas 4G technology which was started within cable television industry in which make users to explore new downloading speeds and capabilities.

The utilization of LTE mobile broadband technology is an opportunity for the corporation to expand its horizons into 4G territory, upstaging current 3G capabilities. The necessity for 4G networks is associated with the increased utilization of data websites such as You Tube and Facebook, which require tremendous bandwidth in order to be used successfully.

The difference of Architecture between both Services can be seen through the block diagram given below:. The transition from first generation 1G , to second generation 2G , then finally to third generation 3G mobile phone technologies is quite distinctly demarcated, and we clearly see which phones belong to each generation.

With the move to the fourth generation 4G , there are a lot of new emerging technologies and a lot more confusion on which one is 4G and which one is not. For starters, 4G is a technology standard while LTE is an actual technology. LTE needs to pass the 4G standards in order to be qualified as a 4G technology. LTE defines how the data is to be encoded and transmitted from one point to another in the cellular network.

In contrast, 4G does not actually define the things that the technology has to do. It simply defines what needs to be achieved. There are more technical specifications, but these two are enough to distinguish 4G from non-4G technologies. Actually, LTE is actually grouped along with other technologies like WiMax as sub-4G technologies; often referred to as 3.

The answer to this is marketing. With many telecoms competing for limited users, they need to come up with ways to entice users. Finally, the4G is basically a data oriented technology offering high throughputs reaching1 Gbps. This is at a coarse level the main difference between the technologies you cited. Note that there are also other differences but that need to enter deeply into details.

Within each of those generations there are various competingh standards, and various "half step" improvements. Each of these is a different modulation scheme, a different protocol stack, different technology architecture, different radio. Signals were transmitted in the digital format and this improved the quality of calls and also reduced the complexity of data transmission.

This means a 3G network actually allows for more data transmission and therefore the network enables voice and video calling, file transmission, internet surfing, online TV, view high definition videos. Happy talking, surfing, conferencing, chatting, networking, partying, or whatever you want to do on your mobile phone. Data rate is about 9. Later 2.
