Because fourth-generation(4G) mobile communications services are rooted in heterogeneous multibands, a unified managementregime fails toaccommodate spectral heterogeneity. This study examined an adequate regimein the 4G era that maximizes spectrum efficiency. A conjoint analysis was conducted to...

Improved internet connectivity has been a consistent aim of Japanese telecommunications policy in the past decades, however, despite the high availability of high speed and ultra-high speed broadband services, actual use has yet to match network capacity. This study hopes to explore this paradox...

The exponential growth in demand of mobile Internet urges mobile network operators (MNOs) to increase the supply of wireless network capacity at a high pace. From this perspective, operators should not only obtain further network capacity but also make a more efficient use of the existing...

Alternative telecommunications operators have continuously invested in their own infrastructure in recent years. After more than a decade since liberalization, competitive conditions have substantially changed, especially in urban areas. European regulatory authorities have acknowledged this...

Fixed telephony has long been a fundamentally important market for European telecommunications operators. The liberalisation and the introduction of regulation in the end of the 1990s, however, allowed new entrants to compete with incumbents at the retail level. A rapid price decline and a...

Social innovation plays an important role in addressing societal challenges. We map Digital Social Innovation (DSI) in terms of the international research efforts and investments made in Europe over the last decade. DSI aims to promote innovation and social change based on the network effect:...
