KT and NEC have completed a proof-of-concept trial for a 5G wireless backhaul system using E-Band 70-GHz to 80-GHz spectrum.

The trial was conducted at the Phoenix Park Ski World resort in South Korea's PyeongChang using KT's commercial mobile infrastructure.

An NEC microwave communications system that operates with E-Band spectrum was used to interconnect KT's LTE base stations

KT plans to use E-Band radio transmissions for its 5G trial services, scheduled to launch in 2018, to serve as mobile backhaul networks in locations such as mountainous areas where it is difficult to install fiber backhaul. 

The companies said the demonstration proves that the characteristics of E-Band spectrum - including its wider communications channels and higher linearity - make it well-suited for large-capacity wireless transmission.

NEC deputy general manager for mobile wireless solutions Hideyuki Muto said the company plans to strengthen its partnership with KT to contribute to the launch of the operator's 5G trial service.
