Technological development of handphones

the handphone technologhy have moved away from a hard-wired networked world to an increasingly wireless networked. With the emergence of Smart Handphones, people on the go prefer to use hand held devices to work on a 24 x 7 basis cutting across geographical and time barriers. The remarkable technological breakthroughs that have taken place in the wireless networking domain have led to the emergence of thriving mobile communities that deliver content-rich applications for the high-end mobile devices that are now readily available.
nowadays the haphones companies have genrated a team of specialist to drive the Mobile Application Development Practice. some organisation of handphones also offer custom mobile application development for a host of smart phones and its various OS(s) including Blackberry, iPhone, Symbian, Windows Mobile, Android and J2ME mobile platforms.

now wit the development of the camera phones. The camera phone, like many complex systems, is the result of converging and enabling technologies. There are dozens of relevant patents dating back as far as the 1960s Compared to digital camera of the 90s, a consumer-viable camera in a mobile phone would require far less power and a higher level of camera electronics integration to permit the miniaturization. The CMOS active pixel image sensor "camera-on-a-chip" developed by Dr. Eric Fossum and his teamin the early 1990s achieved the first step of realizing the modern camera phone as described in a March 1995 Business Week article.[While the first camera phones, as successfully marketed by J-Phone in Japan, used CCD sensors and not CMOS sensors, more than 90% of camera phones sold today use CMOS image sensor technology.
