Fifth generation telephony will enable the development of innovative services thanks to fast data transmission. This include autonomous vehicles, telemedicine, games in the cloud without the need for a console. 5G will also support smart city projects by quickly analyzing data from the Internet of Things sensors. In Poland, we are still waiting for the reduction of electromagnetic radiation standards, because their overstatement blocks the development of the new network.
The fifth generation telephony is getting closer. Huawei predicts that in 2025, 2.5 billion users will use the 5G network worldwide, including all EU countries. However, 5G is much more than telephony or fast video streaming. 5G is the gateway to the truly digital world of connected data.
5G will enable very fast data transfer
There is no doubt that 5G is a revolutionary change compared to previous generations, beating them with the speed of data transfer. 4G (LTE) enables data transmission with a theoretical speed of up to 100 Mb / s even 1 Gb / s., 5G network with a speed of up to 20 Gb / s.
Such a speed of data transfer, with a delay of only 1-2 milliseconds, will allow a real technological leap. It will enable the creation of advanced digital services, contribute to the development of e-health and telemedicine - allowing for remote diagnostics and remote operations.
In industrial production, it will provide a delay-free communication platform in production halls, enabling interactions between machines, Internet of Things (IoT) sensors, and people, support projects related to smart cities (smart elevators, better heating, intelligent traffic management, air quality management and others).
- 5G technology will be based on solutions using sensor networks with specialized functions, such as e.g. property supervision, supervision of industrial or agricultural production, supervision of atmospheric factors, management of locks on rivers, production line or car fleet - says Aleksander Jakubczak, Senior Strategy & Marketing Manager, 5G E2E Architecture at Huawei.
- Another group of applications is the use of very short delays in data transmission, ranging from playing on the stock market in real time, through online games in high resolution, to remote, complex medical operations. This can be of invaluable importance where access to highly qualified staff medical practice is impossible - adds Aleksander Jakubczak.
5G will enable the development of new areas of reality
The introduction of 5G will give impetus to the dissemination of solutions in the field of Augmented Reality (AR) and Virtual Reality (VR) and the so-called Mixed Reality (MR) in work and entertainment.
- The next type of 5G application will be the cloud, in which we can provide a lot of services, starting with a "remote PC" consisting in the need to not buy a physical laptop. We simply buy access to a PC in the cloud and use a 5G smartphone to connect to it from anywhere. The only thing we need is access to the screen of e.g. TV, bluetooth keyboard and mouse and we work exactly like on a physical laptop - explains Aleksander Jakubczak from Huawei.
- Cloud gaming will also develop. So access to video games without having to have a computer or console with the right configuration. This thread can be additionally extended with AR, VR or a mix of both technologies - adds Aleksander Jakubczak.
Initially, 5G will work in conjunction with existing 4G networks to evolve towards independent networks. Fifth generation telephony will also require appropriate devices.
Telephones and 5G modems are now available on the market. The new communication system supports even Huawei Mate '20 X available in Poland. However, you will have to wait for these devices to become widespread. According to IDC, an analytical company, in 2019 only 0.5 percent smartphones will be supported by the 5G network. The real spread of 5G phones and modems will not take place until next year.
The first Polish cities will welcome 5G in 2020
According to the Ministry of Digitization, the construction of 5G will cost between PLN 11.35 - 20.3 billion (excluding the cost of frequency reservations) and will last several years. However, as early as 2020, the fifth generation network will be available in at least one large urban center in Poland.
Selected for the first implementations by the City of Electronic Communications Office are: Koszalin, Olsztyn, Białystok, Bydgoszcz, Toruń, Kielce, Opole, Lublin, Zielona Góra, Gorzów Wielkopolski, Szczecin, Częstochowa, Poznań, Wrocław, Rzeszów, Łódź, Gdańsk, Kraków, Katowice and Warsaw.
However, it should be remembered that the availability of the radio frequency block in a given geographical area does not have to fully coincide with the business plans of each of the infrastructure operators. The main determinant of the order of implementation in the first stage will be the image effect, and in the next - business demand and revenues expected by operators.
5G and the curse of radiation standards
Like previous generations of cellular networks, 5G networks use a base station system that divides their operating territory into sectors and supports the sending and receiving of encoded data via radio waves. Each cell must be connected to the backbone network via forward links built using fiber optic technology. Where it is not available, the base station can be connected to the backbone network by a microwave connection (wireless).
Regardless of the chosen transmission technology, the network will be able to provide reliable two-way communication with specific parameters. 5G can handle up to 1 million devices per 1 kmkw.
Unfortunately, Polish standards are very restrictive due to the high values of electromagnetic radiation (PEM) standards, which currently blocks the development of 5G in our country. The radiation limit in force in Poland is 0.1 W / m2, while most European Union countries adopt for the frequency above 2 GHz limits at the level of 10 W / m2 - a value still considered safe for human health.
Recent recommendations of the World Health Organization classify the field with a intensity 100 times higher than what was considered normative in Poland - at the same level of potential carcinogenicity as aloe and talc for children.
