NEC, Thursday announced the successful completion of a prove of concept trial with KT Corporation (KT) for a 5G wireless backhaul solution that utilizes E-Band spectrum (70-80GHz). The PoC which was using KT's commercial mobile network infrastructure will be a key milestone for KT to launch 5G trial services in 2018.
KT aims to introduce radio transmission using E-Band spectrum in order to establish mobile backhaul networks for 5G services, especially in mountainous areas, where it is difficult to lay optical fibers. E-band spectrum's characteristics, such as wider communications channels, higher linearity and lower atmospheric attenuation compared with other spectrum bands, make it ideal for large-capacity wireless transmission. In this PoC, 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.
