South Korea's KT on Tuesday became the third carrier in the country to launch LTE-based 4G. Its Olleh 4G LTE service is starting up first with four phones, including the Pantech Vega and Samsung's Galaxy S II LTE, Galaxy S II HD LTE, and Galaxy Note LTE. A unique trick of the new network is an adapative system known as Warp: KT can tie as many as 144 cell sites into one virtual station and dynamically put bandwidth where it's needed, potentially avoiding bottlenecks.
