SK Telecom, Samsung Complete 5G Trial at 3.5 GHz

July 3, 2017 — 

SK Telecom and Samsung Electronics have completed an end-to-end trial at 3.5 GHz using Samsung’s 5G virtualized core, virtualized RAN, Distributed Unit (baseband unit and radio unit) and test device that are based on the latest 3GPP 5G NR standards elements.

Results achieved were speeds over 1 Gbps and latency of 1.2 millisecond, which was achieved by reducing the transmission time interval (TTI) down to 0.25 millisecond, or about one quarter of 4G LTE’s transmission time. In addition to the latency improvements, carrier aggregation allowed them to achieve a channel bandwidth of 80 megahertz, while 20 megahertz is the maximum channel bandwidth for LTE, which made consistent gigabit performance possible.

Samsung said virtualization played a significant role in the trial’s success. New applications and functions for services can be deployed with Mobile Edge Computing (MEC), according to the OEM.

SK Telecom and Samsung have been exploring 5G communications in the 28 GHz band, which enables the fast transmission of large volumes of data across wide bandwidths. On the other hand, 3.5 GHz offers a broader, more stable, network coverage area.
