What is 5G?
5G stands for the fifth generation (hence the G) of mobile networks. As you might have expected, there were four previous generations. Two of them will likely sound familiar: 3G and 4G. If you’re currently on your phone without using a Wi-Fi network, you’re probably reading this article through one of those connections. 5G is the most recent version of such mobile networks. It’s still in development and only available in specific locations. Over the coming years, however, it’ll become available worldwide.
Previous generations: 1G, 2G, 3G and 4G
The different generations of our mobile network show how much technology has advanced over the years. Firstly, there was 1G, which enabled mobile phones to communicate with radio towers. This allowed us to call each other without a landline. With 2G, digital communication became possible as well: this is when we all started to text each other. The introduction of 3G meant mobile phones were able to connect to the internet. Finally, from about 2013 onwards, 4G became popular. Smartphones were suddenly able to send and receive more internet data at a higher speed. What does this mean? Well, watching Netflix on your phone has become normal, for example, while it wasn’t before. Now it’s time for the next step: 5G.
Faster internet with 5G
The big advantage of 5G is that it reaches much higher speeds than 4G. It’ll be able to send much more data in the same amount of time. That improvement isn’t small, either: 5G makes your internet connection about a hundred times faster than that of 4G. Any delays that were considered normal with 4G, will be nonexistent with 5G. A fifth generation network will send data in less than a millisecond, while this would take on average 50 milliseconds with the previous network. In other words, 5G will take us from a relatively fast mobile network to an incredibly fast one.
The Possibilities of a 5G Network
You might wonder whether a network that fast is actually necessary. Your phone’s internet works just fine, and you can hardly watch those episodes of The Witcher any faster than you already are. Still, a faster and more stable network has more advantages than you might think. Here are a couple of them:
More stable connections for large groups of people
4G networks can become overloaded quite easily. Whenever there are large groups of people in one location (think of festivals, universities, and airports), users might experience lags. 5G ensures this won’t be a problem anymore, no matter how many smartphones there are within the same square mile. Moreover, the demand for mobile data keeps growing. This isn’t merely because more people are getting access to mobile networks, but also because the number of devices that work with these networks keeps growing. From our smartphones to refrigerators and our smartwatches to smart baby monitors: they all use the internet to send and receive data these days. This data traffic also has to be sent through a mobile network. An effective 5G network could satisfy this growing demand. 5G allows households, companies, and public places to use more smart devices without it affecting the quality and speed of the network.
Less battery use
You need energy in order to be able to send and receive mobile data. That’s why your phone’s battery lasts a lot longer when you turn off 4G or turn on airplane mode. With 5G, it’ll take much less energy for your device to send the same amount of data. Your battery will therefore drain more slowly when using 5G instead of 4G. You’ll have to charge your phone less often, which is just that little bit more convenient. Meanwhile, your internet speed will only increase.
New techniques and the ‘Internet of Things’
5G technology can be used to create new products and services. The Internet of Things (IoT), which refers to all modern devices that are able to communicate via the internet, will grow at a steady pace. Aside from that, 5G allows for higher quality video streaming. This doesn’t just mean your Netflix series will look amazing on your smartphone screen, but also that remote surgery can happen in a safer and better way. There are many more possibilities: think of automatized irrigation systems or drones delivering your mail, for example. Machines could become more automized and perform their set tasks with more efficiency, all due to the fast, endless communication offered by 5G.
Does 5G Endanger Our Privacy?
The upcoming 5G network could contribute to a true technological revolution that will connect all kinds of smart devices to each other. Our online lives will only become bigger and come to include more aspects of our real lives. This has advantages, but also comes with some serious risks, especially in terms of privacy. What happens to all that data that’s being saved and shared online? If the internet knows more about us than we know about ourselves, what does that mean? These are questions that come up again and again. Not only are there technical implications to this, but it also affects the social and political world around us.
Is our personal information safe?
A functional 5G network can handle a lot of data. That means it’ll also be easier to log all kinds of information about its users. The websites you visit, your location, images of the camera in your daughter’s bedroom, and even the health information measured by your Fitbit will all be sent through 5G networks. Often, this information will be used exactly in the way you expect it to be: you’re able to check on your daughter, even when you aren’t at home, and your favorite apps use your data to improve their services. However, your information can also be used against you. This already happens a lot: there are countless parties that are able to watch what you’re doing online. Even marketing companies and, in some cases, cybercriminals could have access to your personal data. Companies might use it to personalize the ads they show you, so they can increase the chance of you spending your money on them. When it comes to black hat hackers, the danger is more obvious: they’ll misuse your data to harm you in whatever way. The more data about us is sent through the air, the bigger the chance that this data might fall into the wrong hands. That’s why many people worry about the negative consequences of 5G. Who knows which parties might end up looking at your online data?
Huawei and 5G
Huawei is one of the companies that might be able to peek at the data that’s being sent through 5G networks. This Chinese company produces telecommunication devices and now also focuses on 5G equipment. You might know their cheap smartphones, which have become very popular the past couple of years. Now Huawei is also developing arguably the best 5G technology in the world. Their 5G antennas are stronger than those of competitors, allowing them to cover greater areas and provide a good quality network. This didn’t happen by accident: Huawei has been investing in 5G for years. Because of the high quality, buying Huawei’s products might seem like a no-brainer, but things aren’t that simple. Since the separation of state and business isn’t as clear-cut in China as it is in most other parts of the world, many people worry about Huawei’s intentions. If our 5G technology is manufactured by a company with ties to the Chinese government, that government might be able to access our data. The fact that Huawei doesn’t clarify how their business is run, only creates more distrust. The company denies any connections to their national government, but suspicion keeps growing.
The US-China trade war
The relationship between China and the United States is complicated, especially since 2016. This affected Huawei greatly. President Trump introduced an import tax of 25% on all Chinese products, which resulted in a trade war between the countries. This caused serious issues for Huawei: their new smartphones weren’t allowed to use any American technology. While Huawei was able to import parts from other countries, the company is still struggling on other fronts. An important example of this is that they’re no longer allowed to use various Google services, including Android, on new devices. Huawei’s reputation has suffered as well. As mentioned before, many suspect that Huawei might spy on its users for the Chinese government. On top of that, the US actively attempts to convince other countries not to cooperate with Chinese businesses, including Huawei. Several European countries are hesitant about letting the Chinese technology into their 5G networks. The table below indicates how specific countries currently think about possible 5G collaborations with Huawei. Clearly, Europe is very divided about this issue. Especially within the EU, this is inconvenient. Multiple ministers called for the European Union to make a unilateral decision. The EU responded with the following guideline: producers that might pose a risk, can be denied a part in the 5G networks. Regardless, the situation shows that setting up a new generation of mobile networking isn’t just affected by technological advances. Political sentiments can also play a huge role.
5G and health
Aside from the possible privacy risks that come with 5G, some people also fear this new network will affect their health. They believe, for example, that the radiation will make us ill. So far, there hasn’t been any research that proved 5G networks actually affect our bodies. So why do people still claim 5G radiation is bad? The fears aren’t completely ungrounded, although they aren’t entirely correct, either. They’ve most probably arisen due to the negative connotation of the word ‘radiation’. Some kinds of radiation are harmful to humans, because they change the molecules in our bodies, which can cause cancer. This is why doctors in the hospital stand behind a wall when they’re taking an x-ray of you. A small amount of this radiation isn’t so bad, but regularly exposing yourself to it is dangerous. The radiation that comes with 1G, 2G, 3G, 4G and 5G does not mutate your molecules. It’s a different kind of radiation called non-ionising radiation. There have been tests that seem to suggest mobile network radiation is dangerous, although none of them have actual conclusive results. For example, one study found small tumors in male rats after exposing them to heavy 3G radiation. However, these results were so minimal that they could have been a coincidence. Plus, the levels of radiation used in this experiment were much higher than the levels of radiation we deal with, even if we were to use our smartphones every hour of every day. Back in 2011, the World Health Organization (WHO) classified the RF radiation released by 4G and 5G as a possibly carcinogen, meaning it might cause cancer. Don’t fret, however. Other common products, like coffee, can be found on this same list. Whether there’s an actual connection between the radiation and cancer, is still up for debate. Research into 5G radiation is still ongoing, but the chances that anything shocking will come to light, are minimal.
When will 5G be available?
The only question remaining is when we’ll be able to use 5G. Different parties have been working on developing transmission towers, producing new smartphones, and testing all equipment on a large scale. Therefore, it won’t take long until we’re all able to enjoy this fast network. All over the world, teams are working on testing and implementing 5G networks. In the United States, for example, there are multiple cities where, provided you have the right kind of smartphone, you can use the faster 5G network already. In the United Kingdom, too, 5G is available in certain areas. South Korea has already made 5G publicly available: since the end of 2018, businesses were able to use it and by now everyone with the right device can. In short, there are multiple places in the world where 5G networks are already up and running. The next step for governments, telecom providers, and other parties is to make 5G available for everyone, whether you live in a big city or not. Within the European Union, the aim is to make this a reality before the end of 2020. North America and parts of Asia are also making huge strides in a short time here. In other places it might take a couple more years.
Conclusion
5G is the next step for mobile networks. It’ll make for faster connections and create all sorts of new technological possibilities. Lags during gaming and streaming on your smartphone will become a thing of the past. What’s more, we’ll be able to use smart devices in the health sector, agriculture, and all sorts of other sectors much more effectively. The possibilities are endless. Simultaneously, however, we have to be wary of the possible consequences this will have for our privacy. Only time will tell, but it can never hurt to be careful!
