The wide deployment of wireless networks and mobile technologies, along with the
significant increase in the number of mobile device users, have CREATED a very strong
demand on various wireless-based, mobile-based software application systems and
enabling technologies. This not only provides many new business opportunities and
challenges to wireless and networking service providers, mobile technology ven-
dors, and software industry and solution integrators, butalso changes and enhances
people’s lives in many areas, including communications, information sharing and
exchange, commerce, home environment, education, and entertainment. Business
organizations and government agencies face new pressure fortechnology updatesto
upgrade their networking infrastructures with wireless connectivity to enhance
enterprise-oriented systems and solutions.
