Software on mobile devices has become increasingly complicated as end users demand a PC-converged user experience on the mobile Internet. This has complicated the software configuration and boot procedures, resulting in a longer boot time. This is damaging to the mobile user experience. Many legacy techniques to enable the fast boot time differentiation in mobile handsets are not applicable to the...
The mobile industry is witnessing a turning point in terms of the increased penetration of PC Internet players such as Apple and Google. The business models of Apple and Google in the mobile industry are very different, however, they are shaking up the legacy mobile software industry by representing a departure from the legacy closed business models. The AppStore represents a great success in the...
Open source software (OSS) has become mainstream in software development, utilizing a global information infrastructure. The term OSS was coined in 1998 during discussion of the public release of Netscape browser software source code. Since then, OSS has continued to increase in visibility in the software industry. Corporate members are showing increasing commitment to OSS projects. OSS is a complicated...
Open source software (OSS) is becoming increasingly visible in the software industry. The entire social and commercial fabric supporting the creation of software is changing. OSS is a global distributed community-oriented model of software development with OSS-oriented licenses. This characteristic of OSS has created a wide range of diversity and heterogeneity in OSS. In order to achieve management,...
Open source software (OSS) is becoming increasingly visible throughout the software industry. The entire social and commercial fabric supporting the creation of software is changing. OSS is a global distributed community-oriented model of software development with an OSS-oriented license. This characteristic of OSS has created a wide range of diversity and heterogeneity in OSS. With less shared common...
The mobile Internet has come to permeate into everyday life. It is expected to accommodate a larger part of the digital economy in the near future. Mobile digital ecosystems have more complicated dynamisms due to the mobile-specific dependencies among their stake-holders. The author presents a framework for mobile digital ecosystems with an entity model, a dynamics model, and an acceptance model....
The ratio of 3G users among wireless subscribers reached 95 %, and the ratio of fiat-rate users reached approximately 50 % in Japan, in 2009. This creates an ideal mobile broadband environment for rich media services. Constraints and diversity as well as the speed of changes, represent the challenges in the development of mobile services. There are several different stage views of the mobile service...
The ratio of flat-rate users among the Japanese mobile Internet users reached 50 % in 2009. This will eliminate one of the major obstacles to the mobile service development. The author presents three chasms and describes how the business models and ecosystem will evolve at each chasm. The author proposes a spiral model of the ecosystem transition. The author also discusses the importance of stage-awareness...
Linux is gaining wide acceptance in the mobile industry as the basis for a mobile middleware platform. It accelerates the increasing visibility of open source software components in mobile middleware platforms. Despite multiple challenges in mobile embedded software engineering, it is crucial to promote open source-aware development in mobile software engineering. The author analyzes three dimensions...
The mobile application development is drastically changing its technical landscape. The author discusses the two major aspects: mobile middle platforms and application stores. Emerging players including Apple and Google pose a challenge toward the existing bundled application model. The author discusses the current technology landscape for middleware and third-party software development ecosystem...
Open source has impacted software industry since its birth. The magnitude of its impact is increasing day by day in a global scale. It is critical for any software vendor to take an appropriate position in the open-source-involved software engineering. The software engineering metrics needs a social dimension to cope with open-source-involved context. After more than a decade of open source activities,...
The mobile Internet emerges and penetrates into every day life. The difference between the mobile Internet and the PC Internet is interesting. It is also important to capture the business model differences if any exists. The author focuses location-based game applications to highlight the mobile specific service development issues. The author proposes a framework model to position location-utilized...
The mobile Internet evolves drastically in the last decade in Japan. The rapid evolution provides pains and challenges for operators, content providers, and client software technology providers. The CPU and memory size evolve in a scale of thousand times. Display resolution evolves in a slightly modest manner. Restrictions, the speed of change, and the diversity of capabilities continues to provide...
Mobile Internet becomes a first-class citizen of Internet in many advanced countries. As increased penetration leverages mobile application business opportunities, it is important to identify methodologies to serve mobile-specific demands. Regularity is one of the important measures to retain and enclose easy-come, easy-go mobile users. It is known that a user with multiple visits in one day with...
The mobile Internet is moving fast-forward into the mobile broadband era. This change is having a definite impact on mobile data service business models. The author presents several observations of the emerging mobile data services in Japan. The mobile business models are two key factors: transaction-oriented or community-oriented. The author highlights the service growth in community services with...
Emerging 3G services offering flat rates have brought notable impacts on the mobile content providers in Japan. Mobile business 2.0 based on the high speed Internet is discussed. A business model shift caused by 3G and flat rate penetration is analyzed and its implications are presented.
Software development is quickly becoming globally distributed. Cross-country-border software development that spans across country borders is a mandatory part of software production today. In order to facilitate global coordination, the transfer of technology is a key. We analyze a successful technology transfer from one time dimension and three factor dimensions. From the lessons learned, we propose...
This paper proposes the application of MIMO to RoF ubiquitous antenna system. As a result of locating remote antennas ubiquitously, it is experimentally found that the effect of MIMO is maintained and throughput performance is improved.
