But over the past few months, Hyundai Heavy deployed a high-speed wireless network across the yard, one of the first such installations in an industrial setting anywhere in the world. Data zips around the complex at four megabits per second, about four times as fast as on a cable modem that is common in U.S. homes. Now, the company can use radio sensors to track the movements of parts as they go from fabrication shop to the side of a drydock and onto a ship under construction. Workers on a vessel can also access plans via notebook computers or handheld phones and hold two-way video conversations with ship designers in the office more than a mile away.
