Design And Implementation Of The Software/Hardware For A Type Of 3G Smartphone

Mobile communication system, after more than 20years'development, turned from analog system to digital system, and to 3rd generation wideband digital communication system, with huge improvement upon system capacity, communication quality, communication security and service content; at the same time integration circuit product offered kinds of ICs, small, fast and functional, with technical innovation; mobile phone consumers began to care for the other functions and user experience instead of the only communication. These three major reasons made the old generation of mobile phone out of date. The market is now requesting a new generation of mobile phone which can support multi-band and multi-technology communication systems, with many functions, funny applications, friendly user interface, happy user experience, fashion style and personality.This article takes advanced ICs and electronic components of Qualcomm, TI, Bosch and etc. to set up the smart phone hardware platform. Google Android platform (Gingerbread) is merged in, and many applications of Google & SonyEricsson are merged, designed or implemented.This article starts from analysis of smart phone market and technical trend, and then details the market requirement items. And then, it carries out design and implementation upon electronic platform, software platform and mechanical platform. And finally, to make sure product quality, it tests upon hardware reliability and software reliability.This design and implementation leads to a mid-high end smart phone with high quality, which owns most of popular functions and applications and which offers both 2G and 3G system support. The most prominent features of this thesis are that, it takes advanced IC and Electronic components in Electronic design, to make sure it has the ability to support complex functions; it takes Google's mobile phone platform Android, and designs based on the latest version to offer the best user experience; it tests the reliability of the smart phone to ensure the lifetime quality warranty.
