SK Telecom and Ericsson to Establish 5G Testbed in 2015

SK-Telecom-and-Ericsson-to-Establish-5G-Test-Bed-in-2015SK Telecom and Ericsson plan to establish a 5G Testbed at SK Telecom’s Bundang Building in 2015 to jointly verify various types of 5G radio access technologies – including 5G small cell – in the Korean mobile environment.

The two companies will develop other 5G technologies with the aim to launch a 5G trial service in 2018 during Winter Olympics at Pyeongchang in South Korea.

In this direction, SK Telecom together with Ericsson successfully demonstrated an innovative 5G small cell system that offers much higher data rates than LTE by drastically suppressing inter-cell interference based on a new 5G radio frame architecture.

Conducted in an area heavily affected by inter-cell interference from multiple neighboring small cells, the demonstration showed that the 5G small cell system more than doubled the cell-edge user performance compared to LTE.

At present, LTE small cells are being used by a wide range of mobile operators to enhance mobile data service quality in heavily congested areas. However, the biggest problem with these LTE small cells is that the service quality degrades with the number of small cells, due to inter-cell interference mainly caused by Cell-specific Reference Signals (CRS) collision.

With the 5G small cell system, SK Telecom and Ericsson move one step closer to the 5G network: To build a 5G network that supports hundreds of times higher quality than LTE, it will be inevitable for mobile carriers to install an increased number of small cells, and the ability to reduce inter-cell interference will translate into an important competitive advantage.

“SK Telecom is delighted to announce the successful development of the 5G small cell system that tackles the root cause of inter-cell interference,” said Alex Jinsung Choi, chief technology officer, SK Telecom.

“With the development of the 5G small cell system, an enabling technology for 5G, we move one step closer to realizing the commercialization of 5G,” said Thomas Noren, vice president and head, Radio, Ericsson.

“Building on our achievement, we will keep collaborating with SK Telecom to develop 5G enabling technologies and services to lead the upcoming 5G market,” added Noren.
