Korea formally launched its 5G Forum in July 2012 and held its first summit the following May. It includes the local giants -- Korea's cellular service providers, LG, Samsung, and the ETRI and KAIST research institutes -- as well as representatives from Intel, National Instruments, and Qualcomm.
Youngnam Han, a KAIST professor who chairs the forum's steering committee, said in an email exchange that he hopes the group can help drive toward collaborations to a single 5G standard.
However, there are "many different situations in spectrum from country to country for the required bandwidth for 5G services, so there may be more than one global standard, considering millimeter wave technologies have such promising potential for 5G," he said. Certainly, "IPR issues will play the key role."
KAIST is doing its share of work on 5G, including validating channel efficiency in simulations using beam division multiple access techniques. In addition, it is collaborating with Samsung in work on 28 GHz radios. Like its counterparts in China, it is also working on massive MIMO antenna technologies.
The local carrier SK Telecom also is exploring millimeter wave services, including the use of "hyper dense" small cell base stations and advanced antenna technologies. Like many others looking into 5G, SK sees a role for emerging work in software-defined networks and network function virtualization.
