5G Network – Jornal Universitário do Porto

In 2019, a brand new 5G community was launched, which promised a big evolution of communication by means of cellular networks within the 2020s. This development is pushed by the development of know-how and the brand new communication wants of the customers.

But nonetheless, what’s 5G community, what’s it for and what’s going to change in using units?

What are the generations of cellular networks?

5G marks the fifth era of cellular networks, a practice that started with the primary era within the Eighties. Net 1 g Chi was revolutionary in making analog communication attainable even with simply the expertise Phone name, With low speeds and lots of safety points and interventions.

After the first era, in 1990, the d 2G Which elevated the safety of the communication and led to the growth of the frequency band the place it occurred, thus rising the capability of the cellular community. The principal innovation of this era was the introduction SMS And MMS As a way of communication, though information switch speeds remained low.

In 2003, the community was launched 3G Which made it attainable to entry the Internet on cellular units Mobile information, Which led to developments within the frequency band utilized in communications and within the velocity of information switch. In addition, cellular community customers can now Video name And see TV and audio-visible content material From gear.

Most lately, in 2010, established 4G Affected the expansion and evolution of picture decision Gaming service. However, the principle development on this era is to extend the web velocity by ten instances the velocity of 3G community..

What modifications do 5G applied sciences deliver?

In an age of know-how wherein increasingly more on a regular basis units rely not solely on digital but additionally on Internet connections, supporting the rising information and knowledge site visitors has turn into important for telecommunications networks. 5G community a Speed ​​improve, Which in keeping with ITU (International Telecommunication Union) information can attain 20 Gbps in downloads (gigabits per second) and 10 Gbps in uploads. This improve means a greater person expertise the place a number of duties may be carried out concurrently with increased information site visitors.

In addition to enhancing the implementation of current communication instruments and processes, this era of cellular networks may also permit the event of latest applied sciences. Virtual actuality And High definition picture circulate.

One of the brand new cellular community functions is the event of Smart citiesWhich contributes to community management Water and power prices. Other areas of use of 5G know-how could possibly be agriculture, trade, e-well being, media and leisure, or the automotive and postal sectors.

What issues have been identified?

Since its introduction globally, the 5G community has been at odds over some points that might trigger issues and obstacles in its operation.

Health issues

Implementing 5G networks utilizing excessive frequencies of electromagnetic radiation has induced concern amongst some customers concerning the results of radiation on well being. Given this concern, a lot of security limits have been launched globally within the vary of frequencies used and the depth of the gear, and are regulated by ANACOM in Portugal. Nevertheless, whereas the results of the electromagnetic subject on well being proceed to be debated, there isn’t any consensus within the scientific neighborhood concerning the medium-time period results.


Due to the bodily variations between 4G and 5G networks, 5G community antennas must be positioned at a barely geographical distance from one another than 4G community antennas. This is because of the truth that the waves utilized in 5G community waves have a low capability to penetrate the waves from the buildings. That means, the placement of the gadget linked to the 5G community is extra correct and also can point out the place the person is. Increasing accuracy may be useful for the event of a geolocation system or in an emergency, however it additionally entails some privateness and private safety points.

5G community protection

Unlike different generations of cellular networks, the 5G community is not going to supply protection throughout the planet without delay. Its institution will rely closely on the funding of telecom operators, who’ve to date centered their operations on massive cities and densely populated areas. In this d Today the distribution of the 5G community is geographically seen on the nperf website map. The United States and Europe have already got massive protection, in distinction to protection within the African continent, the place the community is just accessible in massive cities, in small distribution areas.

With 4G community protection and former generations, it’s estimated that some components of the planet should wait a few years for 5G networks to be carried out.

Portugal has a better protection density alongside the coast, emphasizing the metropolitan areas of Lisbon and Porto, with many inland areas having solely 3G or 2G community entry.

What is necessary to contemplate when shopping for a brand new cell phone?

Mobile telephones are with us every single day they usually have turn into important in numerous duties. The newest fashions are already being constructed with compatibility for 5G know-how however there are nonetheless many choices that do not embody connectivity to this community. If you’ll purchase a cellular phone now, do you have to spend money on a 5G mannequin?

When contemplating this difficulty, you will need to take into account that these units proceed to function in locations the place solely the earlier era of infrastructure, able to utilizing 4G, 3G and even 2G networks, is put in. However, units that aren’t suitable with 5G won’t ever be capable of use the utmost velocity and different options supplied by this community.

In addition, 5G know-how will not be absolutely developed, as it’s within the early phases of mass distribution. Thus, it’s anticipated that, over time, new functions which can be nonetheless unknown will emerge. This kind of innovation could require {hardware} that doesn’t assist the gadget manufactured with present data, which can be a contributing think about suspending the acquisition.

With all this in thoughts, the query of the place to make use of the gadget continues to be geographical location. Since the 5G community protection on the planet will not be anticipated to be uniform, a smartphone with entry to 5G community will deliver extra advantages in case you dwell in an enormous metropolis or on the coast of Portugal.

When is 6G coming?

Generations of cellular networks have been up to date at first of every decade. Therefore, the brand new 6G community is anticipated to be introduced by the organizations by 2030. Next Generation Mobile Networks Alliance. Little is thought concerning the subsequent era, however the principle goals look like to develop extra superior fashions of sensible cities with higher mobility of site visitors lights, vehicles and different providers linked and synchronized by the cellular community.

Speed ​​must be round 95 Gbps, almost 5 instances increased than anticipated for 5G networks, opening up new prospects for sensible know-how.
