Migration to 3G wireless broadband internet and real options: The case of an operator in India

The paper focuses on third generation wireless technologies and on alternative technologies for wireless local area networks. The authors present the evolutionary migration path from second to third generation systems. Technological, economic and behavioral factors related to decision-making towards the migration are proposed. As an example, the paper studies the case of the national incumbent operator of India. It analyzes qualitatively the migration problem from the perspective of the operator, the equipment manufacturer and the users. For the quantitative analysis, real options are used to value the investment decisions. The analysis suggests that the initial (sunk) investment cost, the average revenue per user, the growth of the subscriber base and the volatility of the markets are the key factors in the investment process.     

The 3G transition: Changes in the US wireless industry

The transition of the wireless industry from second generation (2G) to third generation (3G) is more than a simple technology upgrade. The industry's service profile will move far beyond telephony and services will converge with the computing and content sectors. This will bring many more players into this already huge industry. Thus the transition to 3G needs to be regarded as a major economic transformation as it requires a major reconfiguration of the existing value networks. Standards have traditionally been essential in the success of wireless services and will play an increasingly critical role in the future.Due to the on-going transition, wireless standardization has changed considerably—reflecting changes in the configuration of the value network. While the number of major air-interface standards has been reduced to just two, the overall number of standards bodies has increased by almost an order of magnitude while the number and scope of interfaces being standardized has grown at a breathtaking pace. This growth reflects the need to support the industry's new coordination requirements at critical interfaces in the value network. At the same time, the importance of the traditional standards development organizations (SDOs) has diminished as more nimble industry consortia have taken over the main responsibilities for standardization. The major standardization battlegrounds have shifted up the protocol stack to the service enabler level. In addition, the manufacture of handsets and other mobile communication devices is transitioning to a more horizontal industry structure. These changes, along with changes in the way value is extracted from new services and their influence on the reconfiguration of the industry are discussed.     

Investment decisions in troubled times: A Bayesian approach applied to Brazilian firms

This study analyses the investment decision of 497 Brazilian firms during a period of unstable macroeconomic conditions. The role of financial constraints is considered in a Bayesian econometric model. We estimate three different models, and the results indicate the presence of financial restrictions, especially for capital-intensive firms. The recursive predictive density criterion indicates that the most preferred model is the one in which firm-specific effects are correlated with cash-flow. Financial restrictions are more important for capital-intensive firms, probably due to their lower profitability indexes, higher fixed costs and higher degree of property diversification.     

Knowledge management in technology-focused firms in emerging economies: Caveats on capabilities,networks, and real options

In mature economies, technology-focused industries and the management of knowledge are widely viewed as critical to success. Increasingly, in emerging economies technology-focused industries and the management of knowledge are also viewed as important. To date, however, little is known about such activities in emerging economies. Particularly, it is not understood how knowledge management can impact efforts for corporate renewal in such environments. The literatures of the resource-based view of the firm, social capital/network theory, and real options theory are vital to providing insights for technology-focused industries and the management of knowledge in mature economies. In this paper we focus on the caveats when applying such theoretical foundations to emerging economies. To illustrate these issues we will draw on the largest emergent economy in the world, China.

Exploring the potential of wireless technologies to accelerate universal Internet access in Ghana

Ghana was one of the first countries in sub-Saharan Africa to be connected to the Internet, yet has very low Internet usage (5.3 users per 100 inhabitants). A qualitative study including in-depth interviews with ISPs explored Internet diffusion in Ghana. Findings suggest that due to Ghana's inefficient and outdated fixed-line infrastructure, universal Internet access goals might not be achievable through fixed-line technologies. Rather, wireless technologies may be more efficient. However, high access costs continue to be a barrier. Policy options to encourage widespread deployment of wireless broadband and cost reduction are presented as suggestions for further research. These include using universal service funds to expand the national backbone with an open access high capacity wireless backbone to reach unserved and underserved areas, reducing license and regulatory fees for the wireless industry to encourage coverage and capacity expansion, and mandatory infrastructure sharing to reduce cost.     

Third generation new entrants in the European mobile telecommunications industry

This paper focuses on new entrants within the European mobile telecommunications industry. More particularly, the paper identifies those new entrants that emerged from the third-generation (3G) licensing process across Europe before examining how they have fared. Four operators seeking to become new entrants across a range of countries are identified, although only one of them—Hutchison Whampoa trading as ‘3’—is considered to be fully active as a 3G new entrant. It is argued that the success of Hutchison Whampoa to date has been patchy, and that a supportive parent company has significantly contributed to its ability to remain active.
