Earlier this month, Korea Telecom (KT), South Koreas largest broadband provider, began demonstrating early iterations of its 2.3GHz wireless Internet service technology. Expanded tests of the service, including trials with partners from the United States, are due next month.
KTs demonstration included wireless modems attached to mobile devices such as notebooks and PDAs. KTs 2.3GHz technology includes smart antennas and TDD/TDMA, a device for activating frequencies. The devices successfully maintained connection to 2.3GHz wireless LANs service while moving from one location to another. The test showed maximum data transmission speeds of about 1M bps, acceptable performance for most individual and corporate Internet users when compared with broadband Internet service or wireless LAN service. This portends well for future commercialization of these technologies, experts say.
