Economic Issues arising from sharing the Network of IMT-2000
Third-generation mobile telecommunication systems(IMT-2000) will be an essential element of the future telecommunication infrastructures. the characteristics of IMT-2000 such as lumpy investment and vast initial investment would require to set up appropriate plans and strategy for IMT-2000, which consider the national competitive advantages and benefits of end-users. The aim of this study is to investigate the validity of sharing network of IMT-2000. Specifically, this study discusses the validity of introduction of sharing the network and suggests a reasonable way of share the network overcoming the problems generated by sharing the network. Spectrum allocated for IMT-2000 is a finite resource and therefore the number of IMT-2000 license holders will be limited and market will be closed oligopoly. In Korea, three licenses are currently planned in view of the spectrum available. Therefore, sharing the network between service providers would be resonable in the view of promoting competition in the market and reducing investment to build out a network.
