Developing Services for the Wireless Internet offers state-of-the-art technological knowledge and practical know-how to practitioners – project managers, software architects and designers, process engineers and quality assurance workers. The book supports the developers of services and applications for mobile phones, PDAs and smart phones. This new emerging domain is characterized by a very fast pace of change in the underlying technology, exposing products and applications to a constant risk of obsolescence. The relative youth of this field means that knowledge is comparatively limited. The book identifies an approach to mitigate the above risks by focusing on: The development process, the underlying technology and its effects on connectivity, and software architectures. It provides an essential tool kit for all working in this field.
