內(nèi)容概要
To ensure competitive advantage for their companies in wireless product development, developers need to understand how wireless technologies work, what impact they have on applications being developed, and how to use them to optimize products for success in the marketplace. Designed to answer these and other wireless development questions, this unique handbook explores how a host of relevant technologies work together with the new worldwide standards for wireless technologies--General Packet Radio Service (GPRS) and Third Generation (3G). Leading expert Christoffer Andersson clearly explains how GPRS and 3G control the mobile environment, then goes on to describe how the emerging radio technology of Bluetooth fits in with WAP and Java, how wireless applications work with HTTP and TCP/IP on the Internet, and how to create "always-on" wireless applications.
