R&D Achievements
Our first R&D development was a communications repeater based on wireless analog technology standards.
We expanded our R&D portfolio to base station RRU, small cell equipment, and data terminals by using our digital and S/W technology capacities acquired through WiBro system development. Also, we entered into access network equipment and overseas repeater markets in 2014.
