What Is 5G, And How Is It Different From It’s Predecessor 4G

5G is the fifth generation of mobile communication technologies and standards, the successor to 4G, which uses LTE technology. This new generation brings numerous improvements, mainly download speed (how much data can I receive per second), latency (what delay exists between when I ask for information until it arrives) and the number of connected devices in the same area, among other benefits.

Returning to the theme of the futuristic images of 5G that we mentioned in the introduction, it can be seen that the multitude of interconnected points and lines that appear in these images are associated with the large number of devices that this new technology allows serving. So there is a technological and truthful background behind such attractive designs.

How Does 5G Affect Smart Cities

Once we have seen the benefits of 5G, we must understand and analyze which of them may be a potential opportunity for technological solutions to be implemented in the future. Focusing on the Internet of Things ecosystem, and specifically on Smart Cities, we will analyze which of these advantages are relevant in this environment.

First of all, high download speed, one of the most talked-about features, is not entirely relevant for Smart Cities and IoT in general. This is because the volume of data sent from the IoT devices to the cloud, and vice versa, are messages of reduced size and are also usually periodic, so they do not require a continuous flow of data as a streaming video transmission. Likewise, the low latency is not a remarkable feature either since, due to the periodicity of sending, it is not critical to receive data 1 millisecond or 1 second later.

However, the high connection capacity of devices per square kilometer that this communication technology supports does represent a great advance and will allow the deployment of endless IoT devices without worrying about reaching a capacity limit or conflicting. With the rest of the devices and technologies that may be working simultaneously with the 5G network.

In turn, the energy savings in the devices that this communication technology entails will allow them to extend their useful life since, among all the operations carried out by an IoT device (measuring data, processing them, etc.), it transmits the information ( or remain listening to receive it), is one of the tasks that consume the most energy since the radio transceiver must be turned on to do so. This reduction in energy consumption implies a prolongation of the battery life of the devices that will have consequences on the sustainability of this type of solution since, by increasing its useful life, the frequency of battery and device replacement is reduced.

The Importance Of The Type Of Network Used

In addition to the benefits mentioned, 5G has a greater impact on Smart Cities than on other IoT applications because IoT devices in a Smart City are mostly in the air. Free, monitoring and collecting information on different variables such as air quality, mobility, humidity, presence controls, etc.

Why is this detail important? Because the frequency in which 5G is going to operate is going to be in the 3.7 GHz band and, in a wave, the higher its frequency, the greater its attenuation when propagating and, consequently, the obstacles that arise will affect it to a greater extent. Find. This is a drawback emerging from using this technology for many applications. In indoor environments, the existence of architectural barriers such as walls, walls, ceilings, etc., in indoor environments, will cause an attenuation greater than that which could be generated in other ways technologies such as 4G.

However, in the case of Smart Cities, because the deployment of infrastructures is carried out for the most part in open spaces, this does not have to be an obstacle, and therefore the benefits that 5G brings are much greater. Then its drawbacks. The human being is insatiable. Every time we squeeze more and more of the technology that we have, we continually demand new and better functionalities: greater speed, better quality, better processing, longer battery life, etc.

We must begin to consider adopting 5G as the new communication technology for current devices and networks for all these reasons. Due to the undeniably connected future of our cities, it is an obligatory task to focus new infrastructures, fleets, devices and platforms on this technology. But make no mistake, this is not definitive technology. In a few years, it will fall short as has happened with previous technologies, and 6G will knock on our door with another new revolution.

In this article we rehearse a summary of both positions, with useful and verifiable information. It is up to the reader to decide on this matter based on his or her own research, to which we hope to shed some light and vanish all fears regarding our future, with the present information.

Voices Against Saying: The More Power And Speed, The More Health Risks

“Governments are not in control of what is happening and we scientists are very concerned,” said Dr. Ceferino Maestu Unturbe, director of the laboratory of bio electromagnetism at the Center for Biomedical Technology at the Polytechnic University of Madrid, and one of the most relevant scientists studying the impact of artificial electromagnetic fields (EMF) on human health, in Spain.

According to this expert, if they implement 5G as it is now, there will not only be more and more electro-sensitive people, including children, but also childhood leukemia will increase in cases. Another effect would be the appearance of a third type of diabetes whose trigger would be electromagnetic pollution. “By exposing ourselves to this radiation, the functioning of the cells is altered,” specified Magda Havas, another voice against it, a professor of environmental sciences at the Canadian universities of Toronto and Trent. On the other hand, we have the following statements: “It is already impossible to say that radio frequencies do not generate cancer”, this is Professor David O. Carpenter, a physician co-author of the international report “Bioinitiative” and director of the Institute for Health and the Environment, a collaborating center of the World Health Organization (WHO).

A disturbing project was born in 2017. Known as the Mobi-Kids Study, it was carried out in 14 countries and presented to the European Commission. According to Annie Sasco, former director of epidemiology at the National Institute for Health and Medical Research of France, this work could lead to the IARC raising the classification of cell phone microwaves to 2A (probably carcinogenic), due to its neurotoxicity mechanism, since this scientific research links cancer risk for children, adolescents and young people from 7 to 24 years of age in the 14 countries studied to development of brain tumors due to the use of cell phones.

These studies exist, and although they sound too alarming, they come from real scientists and researchers. Now let’s see what the official voices say about the safety of 5G network infrastructure.

The Official Voice Says It: No Trace Of Risk In Speed

The radio signals used by mobile technology are nothing new in 2020. In fact, these electromagnetic waves have been extensively studied for decades. The frequencies used by mobile devices operate in accordance with national regulations or international guidelines for exposure to electromagnetic fields, covering all frequencies used worldwide, and are now considered for future use for 5G.

The final limits for radio frequency transmission devices, such as mobile devices and tablets, intended for public use cannot be changed below 6 GHz. The 2020 update provides additional guidelines for frequencies above 6 GHz. This update was already anticipated by the industry, and test methods are available to ensure regulatory compliance for 5G devices in the market. Public health agencies and expert groups consistently conclude that the guidelines protect all people (including children) against all known health risks.

Finally, a clear upgraded frame was set in March 2020, when ICNIRP stated that the 1998 ICNIRP GUIDELINES still provide protection against all known health effects of high-frequency radiation within the frequency range of 100 kHz – 300 GHz, which is the current 5G uses frequencies below 1 GHz, 1-6 GHz and above 6 GHz.

Is There Really Anything To Be Afraid Of 5G?

Our lives are used to struggle and turn into a battlefield at every level we get to upgrade ourselves, not only professionally, but in every aspect of our day-to-day routine.

Before we jump into our conclusion for this article, as a refreshing advice, let us give to you now a way for peace of mind, at the present time. Lies, dishonesty, robbery, they are not a prerogative of the concrete world. All this technology information is about is integrity of data transfer, so, for preventing hijacking you need reliable PC safety, to get it we should be talking about the best nordvpn review, and set priorities. Prioritizing is an efficient tool to prevent adversities, so we can experience and succeed out of those hard to learn episodes that compose the modern human’s overall reality. Reality is a coin whose two faces are equally important; you must weight both sides in order to decide. If you do not get involved, if you do not take control, someone else will.

Well, now it is our turn to crown this article with our sensible and calm reflection. Although the studies referred do exist, both for and against 5G, it does not seem credible that 5G is a deadly weapon capable of ending the world as soon as the switch of its activation is lifted worldwide. However, we have to raise a voice of sense that hopefully will encourage, calmly but seriously, the public to remain vigilant, because this would not be the only time that there is a lack of studies of safety with respect to a novelty in the world.

To the question, is there anything to fear from the 5G infrastructure? the answer to the date still is: there is not enough evidence to hold great fears up to this day, we do not see the devil in 5G yet. The truth, however, will know how to break through at the right time.

5G Technology Features

First of all, the main thing is to know what 5G technology is, the new wireless communication that is going to revolutionize mobile networks. 5G is the fifth generation of wireless communications with which it is intended to improve connection speeds and end mobile congestion.

5G is a system that differs from its predecessors by using much higher radio frequencies. In this way, it allows us to transfer a greater amount of data in much less time.

The speed of 5G technology will be much faster, allowing you to download or share files in seconds. If we compare the speed of 4G technology with that of 5G, it can be seen very clearly. 4G offers us a speed of 200 Mbps with a latency of 100 milliseconds, while 5G will offer us a speed of 10,000 Mbps with a latency of 1-2 milliseconds.

Therefore, when this new generation of wireless communication is implemented, we will be able to enjoy access to the Internet instantly. So with the introduction of 5G technology, the mobile sector and mobile applications will undergo a great revolution.

Undoubtedly, in the world in which we live in which we are increasingly connected with a wide variety of mobile devices, we need a network that is capable of offering us speed and quality. With 5G Wifi technology, a great revolution will be promoted in all sectors, as it will allow people to connect with everything that surrounds them.

Over the next few months, and even years, we will receive much more information about 5G technology from mobile operators and manufacturers.

5G Technology Advantages And Disadvantages

The most notable advantage of the fifth wireless communications technology is the fast speed it offers you. Also, another advantage is that it provides us with much lower latency, so it allows access to the Internet or the cloud in just seconds.

On the other hand, 5G technology is capable of improving coverage, speed, and capacity thanks to the use of multiple nodes.

Another advantage is that this new technology allows the use of many more devices within the same geographical area. As well as with greater reliability, security and without interruptions in the same area. So in this way, it will be possible to decongest the network.

The main disadvantage of this wireless connection technology is that it is an evolving technology. It is expected that the world population will have full access to the 5G network around the year 2024. Some operators, such as Vodafone, already offer in 5G technology. Even so, we will have to wait to enjoy a full 5G network, since it is a complementary network to wireless communications.
