■ 5G will account for 40% of all subscriptions in 2026. As of 2021, there were approximately 8 billion mobile subscribers worldwide. The number of 5G subscriptions is expected to be 580 million by the end of 2021 and 3.5 billion by 2026, which is 40% of all subscriptions. On the other hand, the peak LTE subscription is expected to reach 4.8 billion units in 2021, and will decrease to 3.9 billion units in 2026. Summarizing the current state of 5G in the world, there are 169 commercial networks, and Ericsson’s equipment is used in 93 commercial networks in 45 countries. Seven of these networks are SA (Stand Alone) 5G networks. ■ 5G penetration rate is expected to rise sharply in GCC countries Looking at the number of mobile subscription contracts by region / wireless system, the ratio of 5G contracts in Northeast Asia, to which Japan belongs, is 9% of the total as of 2020. It has the highest 5G contract ratio. This is followed by 4% in North America, 2% in the Gulf Cooperation Council (composed of 6 countries: GCC, Saudi Arabia, United Arab Emirates (UAE), Bahrain, Oman, Qatar and Kuwait) and 1% in Western Europe. .. Regarding GCC countries, Mr. Fujioka commented that “5G will start up very quickly.” The estimated number of contracts in 2026 is 73%, which is the second highest number after 84% in North America. Looking at changes in the number of 5G subscribers by region, it is expected that the ratio will rise sharply after 2022 in each region except Northeast Asia. This is because the price of 5G smartphones is expected to decline. The forecast that terminals under $ 250 will appear outside China, where low-priced 5G smartphones are currently appearing, and millimeter-wave compatible terminals under $ 400 will appear in the United States is reflected in this change in the number of subscribers. Has been done. ■ Fixed wireless access spreads worldwide The number of fixed wireless access system (FWA, Fixed Wireless Access) providers is increasing, from 103 in December 2018 to 200 in October 2020. It broke through and became 224 operators in April 2021, and the number of FWA operators doubled in less than two years. In addition, 87% of 5G providers offer 4G and 5G FWA, which use mobile networks to provide offices and homes with access to broadband. FWA, which allows quick line opening, is rapidly becoming widespread even in countries with high fiber laying rates, and by the end of 2026, the number of FWA connections will exceed 180 million, and it will be used by about 650 million people. Looking at mobile traffic forecasts, by 2026, 53% of all traffic will come from 5G and 20% from FWA. The average monthly traffic per smartphone is currently over 10GB, with GCC countries accounting for 18.4GB. It is said that the world average will be 35GB in 2026, and it is predicted that the monthly average will be 48GB, especially in Scandinavia. Mobile line connections for IoT devices are also increasing, and are expected to reach 5.4 billion devices by the end of 2026. ■ T-Mobile’s Multi-Band 5G Strategy From here, we will explain the special article (co-authored by T-Mobile in the US) that matches the report. With the acquisition of Sprint and a radio auction, T-Mobile will be able to use 5G-only low-band, mid-band, and high-band radio waves. The company is working on speed lines by combining these. For example, by combining low band and mid band, the average downlink speed of 4G and 5G can be greatly improved. Other merits of using three-layer frequencies are that it can “provide 5G services in areas that can only be reached in the low band,” “extend coverage through carrier aggregation,” and “high-quality voice calls.”
