The diffusion patterns of 3G cellular technologies indicate that the reality is not matching the optimistic estimates of various consulting firms regarding the size of the network. What factors influence the diffusion of rapidly developing network goods? This paper draws upon innovation diffusion literature and the early experiences of 3G mobile technologies to examine the influence of supply-s...

The paper describes the results of the EU FP7 EDGI project concerning how to extend gLite VOswith public and institutional BOINC desktop grids. Beyond simply showing the integration architecture components and services, the main emphasis is on how this integrated architecture can efficiently support parameter study applications, based on the so-calledmetajob concept created by the EDGI project....

With the widespread application of 3G terminals, the security issue of it becomes a paramount issue. This paper proposes a novel 3G terminals security model (3GTSM) to provide efficient support for security. A brief review of the security architecture of 3G communication system is given first, and then the security model, which proposes integration of biometric engine and selectable security mo...

This article tries to give some guidelines to optimize the 3G-2G and 3G-3G handovers, from the extracted experience of a real network in development. The purpose of the adjustment of the 3G-2G handover parameters is to offer the users with dual terminals a quality, equal or better than those ones with only 2G terminals, where in general, the 3G coverage is minor that the 2G one. On the other ha...

Third Generation (3G) mobile devices and services will transform wireless communications into on-line, real-time connectivity. 3G wireless technology will allow an individual to have immediate access to location-specific services that offer information on demand. 3G wireless systems such as 3G-1X, 1xEV-DO and 1xEV-DV provide support for a variety of high-speed data applications. The success of ...

This article develops a map to analyze the dynamic forces that influence the structure and development of 3G (third generation) wireless communications value networks. The analysis builds on the Strategic Value Assessment Model (Fine, et al. [Fine, Charles H., Vardan, Roger, Pethick, Robert, El Hout, Jamal. Rapid-Response Capability in value chain Design. MIT Sloan Manage Rev 2002, 43(Winter): ...
