NEC Corporation has completed a Proof of Concept (PoC) trial with South Korea’s KT Corporation for a 5G wireless backhaul solution that utilizes E-Band spectrum (70GHz-80GHz), reveals a press release from the company. The trial was held at Phoenix Park Ski World in PyeongChang, South Korea, using KT’s commercial mobile network infrastructure.
KT Corporation (KT), a South Korean communications carrier targets to launch 5G trial services in 2018. In 2018, KT will deploy radio transmission using E-Band spectrum to establish mobile backhaul networks for 5G services, especially in mountainous areas where it is difficult to lay optical fiber.
In this trial, the iPASOLINK EX, NEC’s ultra-compact microwave communications system that operates with E-Band spectrum, was used to interconnect KT’s LTE base stations with high-speed and high-capacity wireless links. iPASOLINK EX supports ultra-multilevel modulation (256QAM) technology and hence, it supports the high capacity transmission of up to 3.2Gbps. Moreover, it supports narrow band transmission (channel width of 250MHz and 500MHz), enabling the telecom operators to efficiently utilize the frequency bands assigned to them.
“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,” he said.
