"Large-scale MIMO is a pretty good case of using space resources, [promising to increase the] capacity of base stations 10 times," he said. "China's research on large-scale MIMO is leading the world."

He also said that more than 70 per cent of mobile data traffic is generated indoors. He proposed "distributing different frequencies" for cellular coverage, such as using "low frequencies for outdoor coverage and high frequencies for indoors."

Korea calls on 5G

Korea formally launched its 5G Forum in July 2012 and held its first summit the following May. It includes the local giantsKorea's cellular service providers, LG, Samsung, and the ETRI and KAIST research institutesas 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 towards 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 28GHz 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 virtualisation.
