In a recent test, Samsung Electronics achieved the industry’s fastest 5G speed for the first time.

Samsung used two test terminals powered by its latest 5G modem chipset. These terminals send signals to mmWave access units, achieving transmission rates of approximately 4.3 Gbps per terminal and the industry’s highest rate of 8.5 Gbps in both terminals.

This test uses carrier aggregation technology to aggregate eight 100MHz carrier bandwidths into an ultra-bandwidth of 800MHz. Samsung’s 5G mmWave access unit is used, which contains traditional baseband, radio frequency and antenna. Samsung unveiled its 5G NR mmWave access unit at MWC Los Angeles in October 2019. The access unit uses MIMO technology with more than 1000 antenna elements in a single unit.

According to reports, the peak download rate of 8.5Gbps can support 2900 people watching 720P high-definition video at the same time. If this capability is applied to 5G commercial services, it can help operators easily provide services such as 4K/8K video streaming, AR/VR and smart factories, and can also better provide 5G high-speed services in densely populated areas such as subway stations and large stadiums .

According to the “2020-2025 5G Industry Market In-depth Analysis and Development Strategy Research Report” by the China Research Institute of Industry Research, the 5G penetration rate in South Korea has reached 9.67% at the beginning of this month, close to 10%. In contrast, the United States, which followed South Korea’s launch of 5G commercial services, has a current penetration rate of 0.63%. The United Kingdom, which started commercial use in May last year, has a 5G penetration rate of 0.56%, which is not a small gap with South Korea.

However, South Korea, which is far ahead in terms of 5G penetration rate, does not have an advantage in the number of 5G users. Data from relevant Korean institutions shows that South Korea’s 5G users reached 5.77 million on April 2, with 115,000 5G base stations. In second place, lower than our country.

Foreign media said in the report that South Korea’s 5G penetration rate is far ahead in the world, largely due to the heavy investment of telecom operators.

To drive the adoption of 5G, the three major South Korean telecom operators, SK Telecom, KT and LG Uplus, saw their capital expenditures increase significantly last year, reaching 8.08 trillion won ($6.658 billion), up 60% year-on-year.

South Korean telecom operators have also decided to increase their investment in 5G network construction in the first half of this year, from the previously planned 2.7 trillion won to 4 trillion won (about 3.296 billion U.S. dollars), an increase of nearly 50%.

In addition, South Korean telecom operators also plan to expand the coverage of indoor 5G base stations and install 5G base stations in about 2,000 locations such as subways, airports, and shopping malls.
