DSME has now established the fourth generation of cellular wireless standards (4G) in the shipyard with technology belonging to SK Telecom, and by this means DSME adopted its Long Term Evolution (LTE) wireless communication technology. In the project, DSME first rebuilt the shipyard’s communication infrastructure and Okpo shipyard’s 3G radio wave reception was enhanced, so that the mobile user could access the network even in sealed areas such as the engine room of the vessel. The company also installed more base stations to improve calling during a sea trial. Secondly, DSME developed new applications which can be used on smart phones or tablet PCs.
