SK Telecom Boasts 5G Trial


SK Telecom Boasts 5G Trial

South Korea’s SK Telecom has successfully completed a field trial of 28GHz-based 5G services, describing it as a “key milestone” in the commercialization of 5G. The service provider has been working with Samsung Electronics since October 2015 and this field trial will help it to pilot 5G network by the end of the current year.



The operator has been working on millimetre wave 5G systems and the partners have looked at issues such as service coverage, transmission speed, latency, and radio wave strength.

Technologies applied to the test include transmitter, receivers and antennas designed to effectively transmit radio signals in the 28GHz band, and 3D beamforming, which is “the key technology that compensates radio propagation path loss in the higher frequency bands”.

The Korean telecom service provider plans to discuss efforts as part of the 5G Open Trial Specification Alliance which includes other telcos such as NTT DoCoMo, KT and Verizon.

SK Telecom had earlier announced plans to have some kind of 5G service in operation for the Winter Olympics that will take place in Pyeongchang in 2018. Other service providers such NTT DoCoMo, AT&T, TeliaSonera, MTS and Verizon have announced 5G projects. However, 5G standards are expected to be develop only by 2020.
