Samsung Electronics plans to offer a commercialized PTA solution handset using not only EV-DO technology but also EDGE, UMTS, and WiFi standards.
Push-To-All Technology - Telecom R&D Center
Samsung Electronics' Telecommunications R&D Center is Korea's largest single site R&D center. Since the completion of construction in December of 2001, the approximately 5,000 researchers who work at the site have a host of accomplishments under their belts, including the successful development and launch of the world's first satellite digital multimedia broadcasting (DMB) phone, demonstration of the world's first WiBro (Wireless Broadband), and development of a data broadcasting middleware for 2-way TVs.
