Mobile service provider SK Telecom and Samsung Electronics announced the successful testing of its 5G system at 28 GHz in the outdoor environment in Korea.
The 5G test will pave way for the commercialization of 5G mobile technology, said SK Telecom in a statement on Thursday.
5G Millimeter Wave technologies applied to the test include transmitter, receiver and antenna technologies designed to transmit radio signals in the 28GHz band, as well as 3D beamforming.
Millimeter wave occupy the frequency spectrums from 30 to 300GHz. They have short wavelengths that range from 1 millimeter to 10 millimeters. Currently in the field of mobile telecommunications, millimeter waves generally refer to 6GHz or higher frequency bands.
Samsung Electronics and SK Telecom, which built the millimeter wave 5G system in August 2015, have been conducting field tests using outdoor 5G base stations and a vehicle equipped with a 5G test handset since October 2015 to measure and analyze 5G service quality in the field.
SK Telecom said that the test results will be an important asset for building an enhanced 5G system, including its 5G pilot networks to be built within the end of this year.
SK Telecom began developing 5G specifications since last year to build 5G trial services, and has already completed its development in March 2016.
“This 5G field trial is one of the key milestones for the world’s first 5G commercialization,” said Cheun Kyung-whoon, head of Communications Research Team, Mobile Communications Business at Samsung Electronics.
