Research on Secondary Spectrum Trading Mechanisms Based on Technical and Market Changes

Due to the increase of spectrum demand, the value of spectrum resource has been increased and efficiency of spectrum usage has been important issues in the wireless industry. Therefore recently, there have been many efforts on changing spectrum management framework based on the market mechanism. This research analyzes three different mechanisms as an alternative of secondary trading framework; a brokerage mechanism, auctions and a direct trading. As a consequence, this research suggests an optimal framework for the secondary use trading based on the in-depth simulations which consider different attributes by technical characteristics and market changes and investigate economic values and competition environments.
