Perhaps it's only fitting that South Korea should be grabbing all the headlines out of the 5G Global Summit, a special event for the 2014 ITU Pleniopotentiary Conference (PP-14) aimed at sharing information about 5G technology and facilitating international cooperation. After all, the event is staged in the southern port city of Busan, South Korea.
South Korean giants SK Telecom and Samsung Electronics signed a Memorandum of Understanding to start joint research on 5G network technology and service development.
Given the South Korean mobile communications market is one of the world's most competitive and innovative, it's not surprising to hear that Samsung and SK Telecom have taken the lead on another important enabler of high quality mobile video, MPEG Media Transport (MMT) technology.
Ericsson-LG and South Korean operator SK Telecom agreed to cooperate on research and development efforts involving software-defined networking (SDN), network functions virtualization (NFV) and the cloud, all of which will likely play crucial roles in future 5G networks.
According to analyst firm ABI Research, carriers across the world are moving apace toward LTE-Advanced technology. The firm estimated there are currently roughly 60 LTE-Advanced trials, commitments and commercial deployments worldwide, of which 22 commitments were from Western Europe, 16 from Asia-Pacific, and five from North America.
The South Korean mobile communications market is one of the world's most competitive and innovative. That keeps the pressure on SK Telecom, South Korea's largest mobile service provider, to find way to keep implementing cutting-edge technologies. Editor Tammy Parker recently conducted an email Q&A with Alex Jinsung Choi, executive vice president and head of SK Telecom's ICT R&D division, regarding the operator's roadmaps for LTE-Advanced and 5G. The following is an edited and condensed version of that Q&A.
Nokia aims to get engineers out of the driver's seat by putting spectrum analyzers into base stations, eliminating the need for costly, labor-intensive and time-consuming drive testing to identify and solve radio-frequency interference.
In discussing Cloud RAN and Centralized RAN (C-RAN) distributed base station architectures, the related topic of shifting services away from the network core often pops up.
SK Telecom said it will build out more 1.8 GHz base stations this year to provide 20 MHz of additional LTE bandwidth across South Korea and announced it is moving closer to rolling out a 10 MHz segment of the 2.1 GHz band that will enable it to provide 40 MHz of carrier-aggregated bandwidth.
Sprint along with Nokia Solutions and Networks demonstrated that a single sector of a TD-LTE network can deliver data throughput of 2.6 Gbps.
