Overview

It supplies these units to mobile network operators, with SK Telecom as its primary domestic customer and NTT DoCoMo among its key customers in Japan. Listed on KOSDAQ, Korea's tech-focused small-cap board, the company operates entirely within this single product line and has been supplying both fiber-optic and radio-frequency repeaters for fifth-generation mobile networks.
