KT Tests 5G Backhaul in E-Band with NEC

KT completed a 5G wireless backhaul proof of concept (PoC) in conjunction with NEC.

The test, which was conducted at Phoenix Park Ski World in PyeongChang, South Korea, used KT's commercial mobile network infrastructure. NEC supplied its ultra-compact, iPASOLINK EX microwave communications system operating in E-Band spectrum (70-80GHz).  The microwave radios were used to interconnect KT's LTE base stations.

NEC's iPASOLINK EX supports ultra-multilevel modulation (256QAM) technology for high capacity transmission of up to 3.2Gbps. It also supports narrow band transmission (channel width of 250MHz and 500MHz).

KT aims to launch 5G trial services in 2018. This PoC is based on a collaboration agreement in the field of 5G networks signed between KT and NEC in August 2015. The carrier is considering microwave backhaul using E-Band spectrum for 5G services in mountainous areas, where it is difficult to lay optical fibers.

“We are honored to have contributed to KT's 5G-related trial," said Hideyuki Muto, Deputy General Manager, Mobile Wireless Solution Division, NEC Corporation. “NEC's iPASOLINK EX can operate in harsh environments, and is easy to install at various outdoor locations without large scale installation works because it is compact and light weight. This joint PoC took advantage of these features in order to implement a high-capacity mobile backhaul network in snowy, mountainous areas very quickly. Going forward, NEC will strengthen its partnership with KT to contribute to the launch of their 5G trial services in 2018."

KT Conducts First eMTC Field Trial with Nokia

KT and Nokia announced the industry's first eMTC field trial, marking an important milestone for the Internet of Things, allowing for coexistence with the existing LTE network as well as providing extended coverage.

eMTC, which is also referred to as LTE-M with 1.4MHz bandwidth, is a feature that will be fully standardized with 3GPP Release 13, the first evolution step of LTE-Advanced to LTE-Advanced Pro. eMTC will provide data rates of up to 1Mbps and up to four times better coverage, while reducing device complexity by up to 80%, in comparison to conventional LTE. This allows for cost-effective connectivity of more data-rich sensors, such as environmental monitoring or building surveillance, on existing LTE networks located in rural areas and buildings.

The test was conducted on KT's LTE network using Nokia's Flexi Multiradio 10 Base Station. eMTC utilized only 1.4MHz of the full 20 MHz LTE system, leaving the remaining spectrum free for normal LTE traffic.

Chang Seok Seo, Senior Vice President and Head of Network Strategy Unit, KT, said: "This trial, a world-first, offers a solid platform to promote the widespread application of services powered by IoT technology by addressing limitations that are hampering its spread and reach. Together with Nokia, we will play a pivotal role in pioneering the emergence of IoT as the first-choice technology in Korea and beyond."

Andrew Cope, Head of Korea, Nokia, said: "This project underlines our position as a driving force behind the creation of a programmable world, where close to 50bn devices* will be connected in 2025. With this trial, we have successfully demonstrated the capabilities of LTE as a veritable backbone for a growing range of IoT use cases."

Carriers Verify International VoLTE Roaming

NTT DOCOMO, KT and Verizon Wireless have successfully verified the feasibility of international voice-over-LTE (VoLTE) roaming between different regions of the world.

The carriers have completed a series of tests using S8 Home Routed (S8HR) architecture, a technology based on the existing LTE data roaming platform, which allows speedy commercialization of VoLTE for high-definition voice and video roaming services with full end-to-end carrier-grade voice and video quality.

DOCOMO said it is now prepared to offer its customers the same VoLTE experiences they have in Japan when traveling to other countries.

In the trials, DOCOMO and KT achieved the world's first high-definition voice and video call with full end-to-end quality of service. Also, DOCOMO and Verizon achieved the world's first transoceanic high-definition VoLTE roaming calls. DOCOMO has existing commercial 3G and 4G roaming relations with Verizon Wireless and KT.

The calls were made on an IP eXchange (IPX) and network equipment to replicate commercial networks. With only two months of preparation, which also proved the technology's feasibility of speedy commercialization, the quality of VoLTE roaming calls using S8HR architecture over both short and long distances was proven to be better than that of existing 3G voice roaming services.

DOCOMO will continue to collaborate with these and other companies in the GSMA to drive the industry's ongoing discussion of international VoLTE roaming architecture, and to develop related operational guidelines aiming at the accelerated global deployment as part of the GSMA's Network 2020 Programme. DOCOMO will continue to carry out related R&D as it prepares to commercialize international VoLTE roaming services by the end of 2015.
