KT, South Korea's No.2 mobile operator, said on Wednesday that it had rolled out a nationwide high-speed WiMax service to help meet surging data demand from smartphones, tablets and other mobile devices.
The move comes as KT, which is also the country' top fixed-line carrier, seeks to further sharpen its competitive edge to counter threats from bigger rival SK Telecom, which will join KT in offering Apple Inc.'s iPhone.
KT said it plans to offer a series of smartphones, tablet PCs and laptops compatible with the high-speed WiBro network, which covers 85 percent of the country's population, including Samsung Electronics' Galaxy Tab WiBro, which runs Google Inc.'s Android 2.2 operating system.
WiBro, short for Wireless Broadband, is a South Korean version of Mobile WiMax, a 4G mobile broadband technology that competes with LTE.
Historically, network infrastructure is the most expensive component in a mobile operator's overall CAPEX, which holds true in China, the biggest and fastest growing 4G market in the world.
