Evaluation of the opportunity cost of the spectrum: Application to the digital dividend

The transition to digital television transmission (DTT) creates an opportunity for revising the current allocation and use of the spectrum, and for enhancing its efficiency. The fairly large amount of spectrum that will be freed up in the analog TV switch-off is known as the digital dividend. Many EU countries have decided to partially allocate these frequencies, through market mechanisms, to mobile use, but a large fraction of the dividend is supposed to remain in the hands of broadcasters. An efficient management of the spectrum requires that the use of this resource should be supported through appropriate incentive policies. This paper presents a techno-analytical approach to evaluate the opportunity cost of using a spectrum portion within the digital dividends' bandwidths, for example around 800-900 MHz, for both DVB-T and UMTS services, specifically addressing the extraordinary rise in the use of mobile broadband in the European context. The methodology is then applied to Italy to derive a baseline for administered prices reflecting the cost of spectrum use. Results obtained are then compared with existing evidences from other studies and Countries' experiences. (C) 2011 Elsevier Ltd. All rights reserved.
