SK Telecom and Nokia Networks have achieved a peak mobile speed of an impressive 19.1Gbps during trials of 5G technology candidates.
The companies used quadruple amplitude modulation 8x8 multiple-input-multiple-output (MIMO) transmission technologies and 400 MHz of bandwidth to achieve the blazing-fast speed.
During the proof-of-concept trial SK Telecom and Nokia Networks evaluated radio channel performance over cmWave frequencies.
“With the world’s first demonstration of the cmWave technology, we have reached a significant milestone towards realizing 5G,” SK Telecom CTO Alex Jinsung Choi said in a statement.
“The 19.1Gbps transmission speed we achieved almost meets one of the key capabilities of 5G defined by the ITU-R. SK Telecom will continue to work closely with Nokia Networks to maintain this momentum towards creating a new era of communications.”
Nokia Networks executive vice president for mobile broadband Mar Rouanne added that the vendor is aiming to be “recognized as the enabler of 5G in Korea and across the globe, a goal that is the driving force behind all our R&D efforts in this area.”
SK Telecom and Nokia networks have been closely collaborating on 5G and other mobile broadband developments this year, including by establishing a joint 5G R&D center in South Korea to serve as a testbed for technologies including cloud-based virtualized base stations.
