SK Telecom Builds ‘5G Cluster’ which includes AR, VR, and AI for South Korea

 Overview of ‘5G Cluster:”

SK Telecom today announced its strategy to build ‘5G Cluster’ nationwide to further foster 5G services and benefits.  Since the world’s first “5G” commercialization in April 2019, the number of 5G subscribers in South Korea has surpassed 1 million- far more than in any other country.

SK Telecom’s ‘5G Cluster’ is an advanced 5G environment with cutting-edge ICT including AR, VR, and AI. The Korean telco plans to build ‘5G Cluster’ in business districts, parks, factories, and etc. to provide differentiated 5G service and benefits in both of B2C and B2B sectors.

In the B2C sector, SK Telecom will operate ‘5G League of Legends (LoL) Park’ at Jonggak, Seoul, starting from July 25. At ‘5G LoL Park’, customers can view messages from supporting fans nationwide with Augmented Reality (AR) by facing their smartphones toward a certain location. Customers can also enjoy VR live broadcasting and VR playback during the games.

Starting this August, SK Telecom will provide a service that allows customers to meet a variety of animals, including giant cats and wyverns (a winged two-legged dragon with a barbed tail), using AR in Olympic Park and Yeouido Park, Seoul. For example, if customers hold their smartphones toward ‘The Lone Tree’ in Olympic Park, a giant cat will appear on smartphone screen in AR.

Moreover, the company plans to transform Jamsil Students’ Gymnasium into a 5G Stadium. SKTelecom will further expand 5G experience spaces with immersive media by the end of this year.

In the B2B sector, SK Telecom will apply 5G network and ‘Mobile Edge Computing’ (MEC) solution to SK Hynix to build a ‘5G Smart Factory’. The two companies expect that this will drastically reduce time to detect defective semiconductor products and more efficiently manage production and logistics.

Furthermore, SK Telecom plans to build a total of 12 Mobile Edge Computing (MEC) for 5G networks, to be located at key regions nationwide (South Korea). In particular, the company will provide dedicated 5G edge cloud service for enterprises that are in need of security and ultra-low latency communications, including manufacturing, media, finance, and game industry.

“With ‘5G Cluster’ as our key focus, SK Telecom will provide customers with outstanding service and pleasure that are beyond the imagination,” said Yoo Young-sang, Executive Vice President and Head of MNO Business of SK Telecom. “We will strive to create added values to different industries and regions.”

“We are currently constructing smart factory systems at SK Hynix plants. We expect our 5G services will enable many companies in the manufacturing sector to use the automated logistics system and control manufacturing process in real time,” Yoo said. “By accumulating practical experiences with SK Hynix, we will bring about technological innovation.”

  1. FT: South Koreans complain at poor quality of 5G network.
    Country has 77% of world’s 5G users but service is patchy.

    The world’s first and largest 5G mobile network has come under fire from customers for poor quality, slow connections and lack of applications that use the new technology. South Korea launched 5G in April 2019 and more than 1.6m people had switched to the new service by the end of June, accounting for 77 per cent of the global population of 5G users, according to GSMA, the industry body.

    There are 14 times as many South Koreans using 5G as there are Americans, because of aggressive marketing by telecoms operators and generous subsidies. There are 63,000 5G base stations in South Korea – just 7 per cent of the number of 4G stations.

    But consumers are now complaining that the promise of internet speeds up to 100 times faster than 4G has so far not been met. Users said they often have weak signal and poor connections instead.

    “It seems faster to download a movie than 4G phones but not as fast as I expected,” said one office worker at a telecoms company.

    “And I have experienced some connection problems as well in some areas. I don’t see a big merit of the expensive phone as there are not many specialised contents.” 

    Analysts explained that so far there are not enough base stations for nationwide coverage.

    “The number of base stations falls short of demand,” said Kim Young-woo at SK Securities. “Operators need to expand their facility investment quickly to solve the problem.”

    South Korean operators such as KT Corp, SK Telecom and LG Uplus have spent at least $2.6bn this year alone on 5G technology, according to government estimates, as the country pins high hopes on the new technology to drive growth in the information technology sector. 

    The 5G network was expected to provide a new level of high-speed connectivity that will enable more cutting-edge IT services such as artificial intelligence, autonomous driving and virtual and augmented reality.

    Korean telecom operators are scurrying to improve service quality, by building more base stations and developing new content. They have built about 63,000 5G base stations across the country, which is only 7 per cent of the number of 4G stations, according to government data. 

    LG Uplus, which uses Huawei equipment, has been able to increase its domestic market share since the 5G launch, but it may soon face trouble as the US is pressing its allies to avoid 5G solutions from the Chinese company, analysts said. 

    Competition among smartphone makers to grab a bigger share of the 5G market is expected to intensify in the second half of the year as Samsung plans to unveil a new flagship 5G smartphone in August and a foldable phone later.

    Its Chinese rivals are expected to join the race with more affordable 5G phones. Apple is also expected to introduce its first 5G iPhone next year, which will accelerate the US switch.
