With navigation systems already supporting WiBro, Hyundai and Kia recently announced a deal with KT that will see WiBro connectivity for navigation and other services:

The new "WiBro" feature provided by KT's WiBro service will allow drivers to have high-speed access to a variety of services, including traffic updates, route assistance, weather forecasts and entertainment activities.

"Amid the industry's convergence moves, putting information technology to consumer electronics-related products has become an essential for the technology of future cars. Such technological collaboration mainly focuses on passenger safety and building solid customer relations," according to the company spokesman.

KT also unveiled a new WiBro network for Hyundai Heavy Industries last month at their shipyard in Ulsan:

The service allows workers on the 59.4-million square-meter site to exchange voice, video and data with mobile devices. KT expected its service to enhance productivity of the world's top shipbuilder by allowing real-time tasking not only at the office but also at the shipyard field. This was the first time for a shipyard to adopt WiBro technology.
