 Policy of WiBro acceleration (in Korea)
        Global market status
          85 operators (from 50 countries ) consider WiBro service
          In Malisya, Japan, USA, Saudiaravia
          To enhance the infra of inferior internet environment
          To complement the sufficient internet service
        Recession of Korean WiBro
          limited coverage – capital area
          Demand decrease – well-setup comm. Environment
          Scalable economy difficult – market reduction, product
             monopoly
          Passive investment – uncertain sales, inroad into self-
             market
        Alternative policy for market growth
          Demand increase - Mobile VOIP, public demand creation
          Competence drive – MVNO
          Network open – roaming
          Convergence service utility – telematics
