- Launches tri-band LTE-A service by aggregating three different frequency bands: At its peak speed of 300Mbps, users can download a 1GB movie in just 28 seconds
- Plans to offer a strong coverage by building more than 26,000 2.1GHz base stations within the first quarter of 2015
- With the aim to deliver the highest quality of service, the company will first allow a group of consumers to experience and evaluate the service
SK Telecom (NYSE:SKM) today announced that it launched commercial tri-band LTE-Advanced (LTE-A) service for the first time in the world.
Tri-band LTE-A service offers data speeds of up to 300Mbps by aggregating three component carriers in three different frequency bands: 20MHz bandwidth in 1.8GHz band, 10MHz bandwidth in 800MHz band, and 10MHz bandwidth in 2.1GHz band.
The service is four times faster than LTE and 21 times faster than 3G service. For instance, at its peak speed, Tri-band LTE-A service allows users to download a 1GB movie in only 28 seconds.
Prior to today’s commercialization of tri-band LTE-A Carrier Aggregation (CA), SK Telecom has been offering LTE-A service by aggregating two carriers: It launched 150Mbps LTE-A service by aggregating 10MHz bandwidth in 1.8GHz band and 10MHz bandwidth in 800MHz band in June 2013, and began 225Mbps Wideband LTE-A service by aggregating 20MHz bandwidth in 1.8GHz band and 10MHz bandwidth in 800MHz band in June 2014, both for the first time in the world. The company has developed the world’s first tri-band LTE-A CA technology in January 2014 and successfully demonstrated the 450Mbps tri-band LTE-A by binding three 20MHz bands at the Mobile World Congress 2014, held in Barcelona, Spain in February 2014.
Moreover, with the successful commercialization of tri-band LTE-A CA, SK Telecom not only secures an important edge in LTE-A 4-band CA and 5-band CA, but also moves a step closer to realizing 5G service. The company, under its technology roadmap on 5G, is making aggressive efforts to develop the world’s fastest telecommunication technology.
SK Telecom plans to offer an unmatched tri-band LTE-A service coverage in Korea. In order to provide tri-band LTE-A service, base stations that support three different frequency bands are required. Tri-band LTE-A is offered in areas where coverage of all three component carriers intersect./Tri-band LTE-A is offered in areas where signals from all three frequency bands – i.e. 800MHz, 1.8GHz, 2.1GHz – overlap
Since the company has already secured Wideband LTE-A coverage in main areas of all 84 cities nationwide – meaning that it already has in place 800MHz and 1.8GHz base stations – it can offer tri-band LTE-A service by simply adding 2.1GHz base stations. The company plans to build more than 26,000 2.1GHz base stations within the first quarter of 2015 to provide its customers with the fastest mobile telecommunications service in Seoul/ Seoul Metropolitan Area, central areas of all cities nationwide as well as all subway lines in Korea.
Galaxy Note 4 S-LTE, the first tri-band LTE-A capable device, will first be sold limitedly to a group of consumers who wish to use the service ahead of others and provide feedback on issues including its performance (e.g. speed, transmission stability, etc.) and convenience features. Through this process, SK Telecom aims to further improve its tri-band LTE-A service to better meet its customers’ needs and provide them with greater value through new mobile value-added services optimized for the ultra-fast tri-band LTE-A. SK Telecom subscribers, including this group of early users, will be able to enjoy the new service at the same price as LTE.

SK Telecom and Ericsson Develop Smart Wake-Up Technology [press release]
- Smart Wake-Up Technology decreases interference between base stations and therefore improves data transmission speeds by controlling operation of idle base stations during late night and early morning
- Improves energy-efficiency of networks by reducing energy waste through intelligent cell operation
SK Telecom (NYSE:SKM) today announced that the company, together with Ericsson, the world-renowned telecommunications technology and service provider, are the first to develop Smart Wake-up, a technology that dynamically wakes up small cells when traffic enters the cell, improving operational efficiency and user experience.
Smart Wake-Up is a new technology to control the operation of idle base stations during late night and early morning. Through intelligent operation control, the base station will be turned off when no mobile phone is detected within the cell boundary, but if any device comes into the coverage then the base station will automatically sense it and reactivate itself.
■ Smart Wake-Up
With the support of Smart Wake-Up, decreased number of active base stations will reduce interference between cells and therefore speed up the data transmission between base stations and devices.
Applying the technology, SK Telecom expects to save operating costs of base stations and enhance durability of networking equipment by mitigating power waste of inactive base stations while improving energy-efficiency of networks.
Energy-efficient network has been rising in importance along with environmental pollution and energy consumption and, accordingly, lively discussions concerning the issue are taking place globally, for example, in ‘Green Touch’, the global consortium for improving the energy efficiency of ICT, and 3GPP, a group for telecommunications technology standardization. Also, energy efficient networking, as a core technology for the next generation mobile communications network, is one of the major agenda items in 5G network discussions including 5G Forum and 5GPPP.
In the recent tests of the technology, SK Telecom confirmed that use of Smart Wake-Up increased data throughput by 18% and reduced power consumption of the base station by 21% while still providing seamless service by reactivating the cell if detected access by a terminal.
Park Jin-hyo, Senior Vice President and Head of Network Technology R&D Center at SK Telecom, said, “Once commercialized, SK Telecom expects the Smart Wake-Up technology to substantially enhance efficiency in networking equipment operation by achieving both network quality improvement and energy saving”.
Thomas Norén, Vice President and Head of Radio Product Management at Ericsson, said, “Ericsson is pleased to cooperate with SK Telecom to maximize the customer experience; especially in today’s environment where the number of LTE subscribers and mobile data traffic is soaring fast. Together with SK Telecom, Ericsson will continue its efforts in technology development to improve the efficiency of network operation”.
January 8, 2015: CES 2015: The Power of 5G Erik Ekudden, VP, Technology Strategy, discusses the importance of Ericsson’s innovation in 5G development – leading the way forward to deliver faster, high-performance mobile broadband that meets the growing challenges of the Networked Society in 2020.
July 21, 2014: SK Telecom and Ericsson Achieve World’s First Demonstration of Elastic Cell, a Key Enabler for 5G [press release]
- The Elastic Cell technology will transform the current cell-centric network environment to a user-centric one.
- Demonstrating data transfer rate improved by up to 50 percent at the cell-edge, SK Telecom aims to commercially launch the technology by 2016.
SK Telecom (NYSE:SKM) today announced that the company, together with Ericsson, the world-renowned telecommunications technology and service provider, successfully demonstrated the Elastic Cell technology on July 21. The technology, demonstrated for the first time in the world, is expected to become a key enabler for 5G.
Elastic cell, also known as Flexible Cell, is a new technology that enables multiple cells near the handset to cooperate for every transmission thereby creating a user-centric environment, compared to the current cell-centric one where each handset communicates with only one specific cell.
A serving cell receives information on nearby cells from a handset and selects a group of cells that can improve the network quality in the cell-edge for transmission while temporarily turning off the cells that cause interferences. As a result, Elastic Cell can ensure more seamless data transmission by preventing possible quality degradation that can occur when the handset moves across cell boundaries.
According to SK Telecom and Ericsson, the demonstration confirmed that the technology can improve data transfer rate by up to 50 percent at the cell boundary areas compared to the existing LTE network. With an aim to commercialize Elastic Cell by 2016, SK Telecom will continue to advance the technology.
Once applied, Elastic Cell will enable SK Telecom to provide the most optimized network service to each individual device regardless of its location while bringing the company one step closer to achieving the goal of ‘1Gbps data throughput anywhere’ which is also one of major issues in the minds of ‘METIS (Mobile and wireless communications Enablers for the Twenty-twenty Information Society)’, an EU project for 5G research, and 5G Forum, an industry-academia R&D partnership for 5G in Korea.
Park Jin-hyo, Senior Vice President and Head of Network Technology R&D Center at SK Telecom, said, “SK Telecom, together with Ericsson, succeeded in the world’s first demonstration of Elastic Cell which is expected to become a prerequisite for the next generation network. We will continue to take the lead in developing a variety of technologies necessary to evolve cells.”
Thomas Norén, Vice President and Head of Product Area Radio, Ericsson says: “With this new technology SK Telecom takes an important step toward the next generation of mobile networks. Consumers will benefit from the improved seamless experience wherever they are in the cell and while on the move. SK Telecom has been a leader in technology development of 4G and beyond and we are proud to support the developments.”
Earlier on July 6, the two companies signed a memorandum of understanding at Ericsson’s headquarters in Stockholm, Sweden for joint research on 5G technologies.
