In recent years, many doubts and concerns have arisen about the change towards fifth generation technologies and if there really are big differences between 4G and 5G in the field of mobile telephony.
We are at a time in history when the advancement of technology is so fast that it can become complex to keep up with new trends. This lack of knowledge can provoke rejection in certain users , but the truth is that since the birth of the first generation of mobile networks in the 80s, the same questions have existed about whether a change to a new system is necessary .
However, we must not forget that thanks to the changes of generation that have occurred in recent decades, it has been possible not only to increase the quality of calls, but also to allow the transmission of mobile data, which has made possible the arrival of smartphones and all the technological revolution that this has entailed. Know more about the digital notebook.
Thanks to the arrival of 5G, endless new opportunities are opening up in all technological fields, from the transport sector to the health sector, including communications.
If you don’t believe us, you just have to take a look at the selection of second-hand smartphone models with 5G that we have at Cash Converters and see for yourself everything they are capable of doing, for a very affordable price, with two-year warranty and helping to promote more responsible and environmentally friendly consumption.
Main differences between 4G and 5G
As we have seen, this fifth generation is presented as a promising change that will drastically modify mobile networks, but are there really so many differences between 4G and 5G?
That is what we are going to analyze in this article, what are the main differences between 4G and 5G and if it is worth the deployment and global investment towards this new technology, which today is not yet 100% operational in all countries. You might be interested in a cream whisk.
Without a doubt, speed is one of the factors that stands out the most when comparing the differences between 4G and 5G. And it is not surprising, since with each generation change this parameter has increased considerably.
It is estimated that 5G can be 100 times faster than 4G, reaching a theoretical speed of around 20 Gbps, unlike its predecessor, which is only around 100 Mbps.
This speed will allow downloading, for example, a movie of about two hours in 10 seconds, an action that with 4G takes about 10 minutes if you have a good connection.
This is possible thanks to the high band spectrum with which 5G works, which allows greater data transmission in shorter periods of time . However, the main disadvantage of this type of signal is its low ability to cross surfaces and travel long distances.
Quite a challenge for mobile operators in a society in which we make use of devices in all kinds of situations and places, such as in the subway or in an underground car park. To solve this problem, a large investment is necessary to create a high-band network. Know more about the squatty potty.
The time it takes for an information packet to travel between two points is what is measured by latency. In other words, it is a term that is used to determine the delay that can occur in a data transfer , regardless of the speed of the connection.
According to experts, latency is another of the big differences between 4G and 5G to highlight. And it is that while with fourth generation networks the normal latency oscillates around 50 milliseconds , it is estimated that with fifth generation networks it will be minimized to 1 millisecond .
And although for an average user this may not make a big difference, it will allow devices to process data directly from the cloud in a much more efficient and precise way, allowing the development of all kinds of industrial applications , such as vehicles. self-driving in real time by an artificial intelligence or heavy machinery controlled remotely by an operator.
Another of the big differences between 4G and 5G is coverage.
Even today there are rural or remote areas that do not have optimal 4G coverage. However, the capacity of this fourth generation is still much higher than that of 5G due to its extensive network that has been built over a decade.
It will take several years to create a 5G network similar to the existing 4G and capable of supporting the different types of band. This lack of a fifth generation network is responsible for the fact that today a mixture of the two is used and that many devices, such as smartphones, support both.
The efficient use of the available spectrum or the capacity of this new generation is another of the great differences between 4G and 5G to highlight.
While 4G only makes use of a limited portion of the spectrum (from 600 MHz to 2.5 HHz), 5G divides it into three different bands , each with its own speed and frequency range.
This division makes it possible for each of the bands to be used in a different way, thus increasing the capacity of the network and avoiding congestion due to an agglomeration of devices .
expectations vs. reality of 5G
Although on paper the differences between 4G and 5G are significant and manage to highlight all the benefits of using this fifth generation of the network, it is necessary to analyze what 4G promised and what it actually offered, in order to determine how far it will be possible . come the technological advance of 5G .
At the end of the day, many of the goals proposed by 5G are still an extension of the original goals of 4G that were ultimately not achieved due to the limitations of the technology .
