At a high-security inspection of the Evergreen Group's Seventh Container Terminal on May 7, Chunghwa Telecom's CTO & SEVP, Chih-Hsiung Huang, acknowledged that limitations in domestic 5G Open Radio Access Network (O-RAN) technology have made it unsuitable for the expansive port environment. As a result, the 5G private network deployed at the terminal continues to rely on base stations provided by Nokia and Ericsson.
