New Generation: the world's first commercial 5G network launched

    The Finnish telecommunications company Elisa announced the creation of the first commercial 5G network in the world. This marked the beginning of a race in the new generation network market.

    Let's see how things are with the 5G networks in different countries and what technologies are being developed to spur the development of the entire ecosystem.

    The success of the Finnish operator

    In late June, it became known that mobile operator Elisa launched the world's first 5G network for commercial use. She works in the Finnish city of Tempere and the Estonian capital Tallinn.

    With the help of a new network already held the first communication session. They were a video call between the Minister of Transport and Communications of Finland Anne Berner (Anne Berner) and the Minister of Economics of Estonia Kadri Simson (Kadri Simson). They used the first commercial 5G terminals developed by the Chinese company Huawei. According to Berner, the Finnish government is ready to begin issuing the first licenses for the creation of 5G networks at frequencies of 3.4-3.8 GHz this fall.

    Testing the new generation network Elisa conductedback in February. At that time, its capabilities were also checked using Huawei terminals located in vehicles moving in the Pasila, Helsinki area. According to the test results, the download speed was 1 Gbit / s, and the upload speed was 400 Mbps.

    Plans for other operators

    Other companies have also announced plans to launch 5G commercial networks. For example, one of them is the AT & T telecommunications conglomerate. By the end of the year, the operator expects to implement access to 5G for residents of twelve US cities. First on the list will be Dallas and Waco in Texas, Atlanta in Georgia, as well as Charlotte and Raleigh in North Carolina.

    The company plans to use a range of low (600 Hz and 700 Hz), mid (3.5 GHz) and high frequencies (50 GHz) in accordance with the 3GPP industry standard published in June.

    Another major American operator that will launch5G network soon, - Verizon. At the end of 2018 or the beginning of 2019, the company will raise its network in Los Angeles, Sacramento and Houston. In the last two cities, Samsung will help create the infrastructure for the Verizon network .

    Providers of South Korea are also actively working on the deployment of 5G networks in the country. For example, SK Telecom recently acquired frequency bands (at 3.5 GHz and 28 GHz). The second provider, Korea Telecom, plans to launch a new generation network in March 2019. Testing operator conducted during the Winter Olympic Games in Korea. The network will “cover” the cities of Gangneung, Bugwan, Jeongseon, Pyeongchang and Seoul itself.

    Japanese operators also plan to implementa commercial 5G network for the Olympic Games, but for others - those that will be held in Tokyo in 2020. Service providers are already testing.

    Technology for 5G development

    More and more providers plan to launch 5G. Therefore, more and more companies are developing devices and technologies that would give users the opportunity to work in these networks.

    LG, Sony, HTC, ASUS, Xiaomi and other brands create smartphones based on the Snapdragon X50 modem and the Qualcomm antenna module , which consists of four antennas that form a phased antenna array . Thanks to her, he can control the direction of radiation, improving the quality of the signal. MediaTek, Samsung and Huawei are also working on their 5G chips . In particular, MediaTek modem called Helio M70will enter the market next year.

    Creating a 5G network should also spur the development of the Internet of things, because Qualcomm not only creates hardware components for smartphones, but also a software solution for IoT devices. Qualcomm Wireless Edge Services will facilitate integration and data exchange between 4G and 5G gadgets.

    But Nokia is working to improve the effectiveness of 5G-networks. It develops a system that, using beam forming technology ( beamforming) allows you to maintain a high data transfer rate in places where thick walls interfere with signal propagation. The device is able to “feel” the loss of the signal and debug the transmitter in an appropriate way — machine learning algorithms will be used for this. Nokia will test its developments in the 5G network of the Chinese operator China Mobile.

    Future forecasts

    New generation networks will begin to actively develop after 2020, and the peak of this development will be in the countries of Asia and the USA.

    It is expected that by 2022, half of mobile subscribers in South Korea and the United States will use 5G. According to the report of the trade organization GSMA, the number of connections in China by 2025 will be 430 million.
