History

2023: Recognition of the failure to launch 5G networks

In mid-August 2023, SK Telecom, South Korea's largest mobile operator, released a document according to which the commercial launch of 5G networks was far from as successful as industry participants predicted.

The report said 5G technology was over-hyped, but its practical implementation fell short of expectations. Cellular operators presented 5G as a breakthrough platform for the creation of robotic transport, next-generation unmanned aerial vehicles, advanced reality (XR) services and digital twins. But in fact, many such projects have remained unrealized due to the lack of consumer equipment, the immaturity of technologies and services, low or absent market demand, and regulatory problems.

SK Telecom admits 5G network launch was not as successful

SK Telecom emphasizes that some of the tasks set by the international standardization organization ITU-R for 5G have been successfully solved. But other goals as of mid-August 2023 have not been achieved, despite the fact that the first commercial 5G services began to be provided in 2019.

And yet in certain areas, the document notes, 5G technology has provided significant advantages over previous generations of networks. This is a significant increase in throughput with less delay. As a result, a 70 percent reduction in the cost of data transfer per gigabyte was achieved compared to 4G. At the same time, subscribers in 5G networks download 50% more content than those connected to 4G services.

The 6G standard, which will debut approximately in 2030, is expected to avoid mistakes made in the commercial implementation of 5G. SK Telecom said it plans to actively pursue 6G developments and promote South Korea as a global leader in communications technology.^[1]

2019: Launch of the first 5G network

On April 3, 2019, South Korea announced the launch of the world's first commercial fifth generation (5G) network, operating at a nationwide level. For its functioning, telecommunications operator SK Telecom has deployed 34 thousand base stations that cover the most densely populated areas in 85 cities of the country.

The high-speed mobile network, which allows data transfer 20 times faster than the technology, LTE is already operating in some regions, but its official commissioning is scheduled for April 5, 2019 - the launch day of the first smartphone Samsung with 5G support (). Galaxy S10

SK Telecom expects 1 million subscribers to be connected to the 5G network by the end of 2019. In total, the company has 27 million customers by the beginning of April 2019.

As noted by the Reuters news agency, South Korean cellular companies spent billions on marketing campaigns dedicated to the launch of 5G networks. For example, SK Telecom attracted music stars and an Olympic champion to advertise.

Another South Korean operator - KT Corp - is set to offer better tariff plans for 5G users. They will include unlimited internet and the ability to buy 5G devices in installments for four years.

Telecom giants in South Korea planned to launch 5G networks in March 2019, but there was a delay due to the need for additional equipment testing. In addition, SK Telecom was unable to agree with the government on the cost of servicing the new network, which also led to a delay.

SK Telecom reported that the company's base stations are capable of providing subscribers with transmission speeds up to 2.4 Gbps. Such fast Internet access will open up new opportunities not only for ordinary users, but also for companies, significantly accelerating the development of the Internet of Things and self-driving cars.^[2]
