It is equipped with all the necessary features for optimal support of real-time and best-effort traffic with seamless mobility. This article overviews the UMB technology, and discusses its competitive advantages, which are fast time to market, flexible deployment options, inherently designed for real-time services and flexible IP-based network architecture. Moreover, the article analyzes key UMB design features, including Orthogonal Frequency Division Multiple Access (OFDMA), advanced antenna techniques, Reverse Link (RL) sector capacity optimization, adaptive interference management mechanisms, efficient RL control design, low-overhead signaling, fast seamless handoffs, multi-carrier support and beacons, enhanced terminal battery life, and flexible IP-based network architecture. UMB is well suited to be at the center of the future that melds broadband applications with faster, more capable mobile multimedia devices. UMB’s competitive advantages provide operators with continuous differentiation today and tomorrow.展开更多

An IT infrastructure that possesses elements unique to a particular organization and difficult to duplicate can produce competitive advantage. To achieve this advantage, not only the inner integration of technology, personnel and business process in a firm is needed, but also a platform for electronic commerce is required. The purpose of this study is to establish the whole concept framework for IT infrastructure, based on competitive advantage, and to propose ideas about the construction of IT infrastructure system.展开更多

Cloud computing services evolved from distributed, grid, and utility computing. Critical companies such as Salesforce,Amazon, Google, and Microsoft play important roles in cloud computing. Dramatic changes in the technology environment have created new challenges for current information technologies. This study discusses four significant challenges for cloud computing services,including the next-generation Internet, data synchronization, cloud security, and competitive advantages.And then it also discusses how managers can learn about the future of cloud computing services.展开更多

The analysis results show that under either the case with no environmental regulation or that with a tariff levied on the dirty product, the clean firm would always get more profit. In addition, the stricter the regulation is, the more profit the clean finn would obtain. This can verify that from the view of product differentiation, a firm could improve its corporate competitiveness with environmental management.展开更多

Based on a typically multiplex marketing channel system of mobile manufacturer, the analytic hierarchy process （~HP） structure model is established. Through the judgment matrix, simple and total hierarchy arrangement, consistent test, this paper gets the weight of each kind of marketing channel of mobile manufacturer, it provides the practical reference value for mobile manufacturers to distribute resources of marketing channels.展开更多
