Why is 5G so much faster than 4G?

The evolution to 5G will make it possible to call, write and, above all, surf the Internet at high speed, also having a greater capacity for mobile devices connected simultaneously. With the bandwidth of the 5G network, the devices will be able to enjoy speeds between ten and twenty times faster, yes, it will be necessary to have a 5G mobile.


1. Operation: use of new frequencies

One of the first differences that we find between 5G and 4G is the operation. Since the new mobile network makes use of unique 5G radio frequencies. In this way, it achieves something that the previous generation failed to achieve. The radio spectrum is something that is divided into bands, each one having unique characteristics as it increases at higher frequencies.

However, it is not a change that we are going to experience now for the first time, but if we look back we will remember that the transition from 3G to 4G connectivity was not so long ago and that the maximum upload and download speed considerably improved. and navigation of mobile devices. This is just the next evolutionary step.

In addition, its arrival will not only affect your mobile phone, but augmented reality and artificial intelligence are some of the fields that will also improve a lot with the implementation of 5G. Among its main advances is latency time.

Latency time is nothing more than the transfer time of data packets within a network. The developers promise that this will be reduced to between 1 and 2 milliseconds, which will allow, for example, to reduce the response time of electric cars and, therefore, also increase their safety.


2. Differences between 5G and 4G

In the case of 4G networks frequencies below 6 GHz are used. On the contrary, with the new 5G technology, extremely high frequencies will be used, which could go from a range of between 30 GHz to 300 GHz in some cases. High frequencies can have many advantages. Especially since they support a large data capacity at high speed.

This helps them to be less saturated with data. So, it would be possible to use them to increase the demand for bandwidth. They can also be configured with other wireless signals without causing any interference. It is noticeably different from 4G towers, which shoot data in all directions. This is something that wastes energy.

Also, it should be mentioned that 5G makes use of shorter wavelengths. This helps the antennas to be smaller than the current ones. Something that would help to support more than 1,000 devices per meter than those offered by 4G. In addition, it allows to send data at a higher speed, to a greater number of users.

Another of the big differences between the two is that 5G networks will be able to understand more easily the type of data that is being requested. In this way, it will be able to switch to a lower power mode when not in use. And it will automatically switch back to a higher power mode when doing some activity that requires a higher amount.


3. Speed: 5G is 20 times faster

Another of the big differences refers to speed. If we focus on speed, 5G is 20 times faster than 4G. It means that in the time a piece of data is downloaded with 4G (think of a file, like a movie or a video), the same file could have been downloaded 20 times using a 5G network. The difference in both cases is remarkable.

5G offers a maximum download speed of 20 Gb / s, while that of its predecessor is 1 Gb / s. Although these speeds will vary depending on the moment, since they refer to a device that does not move. 

Regarding the decrease in latency, 5G promises to lower it from the 100 milliseconds of 4G networks to between 1 and 2 milliseconds. This will make Internet connections virtually instantaneous. This wireless connection, together with the download speeds, will make accessing content posted in the cloud almost as fast as accessing a document from your own mobile device.

Leaving aside speed and latency, 5G has also solved some technological problems that 4G was dragging on, such as battery consumption, now 10% more durable. In addition, it will be easier to implement, it will be able to support 100 billion connections and a 90% energy saving per service provided.


4. What can we do with 5G that we cannot do with 4G?

It is not expected that there will be significant changes in the functions that users can make. We can carry out the same actions as with 4G, only in this case some improvements arrive. As we have mentioned, speed is the main change, with a notable increase. It will allow that web pages load faster, that the videos load faster or that we have less problems when making a videocall.
