This study identifies and analyzes the causes for WiBro's failure in the Korean telecommunications market within the context of the technological systems framework and the actor-network theory. The reverse salients of WiBro were identified according to the activities of the actors from three...

With the increasing use of smart devices recently, mobile traffic has been increasing rapidly, which in turn results in greater demand for the frequency. Many countries have attempted to use the vacant frequencies known as TV White Space (TVWS) in an effort to solve the frequency problem. Super...

This paper forecasts 3G mobile subscription in mainland China while incorporating regional disparity. First, using stochastic frontier analysis, this paper tries to measure the relative market potential of 2G mobile service in 31 Chinese provinces. Second, this paper estimates diffusion...

This article investigates whether acquiring telecommunications firms managed their earnings by means of discretionary accruals prior to the announcement of stock-for-stock takeovers in the U.S. telecommunications industry during the period of 1990 to 2006. The results show that acquiring...

This paper proposes a new estimation method of total cost and average cost curves and applies it to the telecommunications industry. The method is more flexible and entails less hassle for data collection than traditional methods. The results show that the long-run average cost (LRAC) curve is...
