Local mobile carriers are aggressively expanding their long-term evolution (LTE) networks but this is raising concern among some observers that Korea maybe going a little too fast and could lose money and isolate itself technology-wise. SK Telecom, KT and LG Uplus have poured trillions of won in building additional radio stations and access points for LTE across the country since 2011.
No country has a higher penetration of the fourth-generation (4G) network than Korea, though the United States and China obviously have a higher number of subscribers. Over 60 percent of smartphone owners in Korea use LTE, which amounts to 16 million people, according to local analysts. Korea is the only country embracing LTE technology at this rate. The U.S. and China still widely use 2G and 3G connections. In Europe, the LTE market is just blossoming, and developing nations are still in the process of transitioning.
