7. WiBro Coverage Expansion PlanⅠ. SKT WiBro Business Progress Status

WiBro Coverage Expansion is to disperse HSDPA Traffic and to sustain marketing competiveness so that Seoul and Metropolitan areas will be invested largely and

additional Hot Zone will build up at local area including provincial seats

1. Network Evolution (4G)II. WiBro Technology Trends

LTE, UMB, 802.16m, etc. are expected to be suggested as the candidate technology of 4G which will be standardized on 2010, and there is going to be the limitation of securing

compatibility with current system because all of their technologies are based on OFDM
