Thera pocket PC with integrated CDMA 2000 1X wireless voice and data

摘要

Toshiba started to ship a pocket PC with an integrated CDMA cellular phone in May 2002. This is the world's first device with CDMA 2000 1x communication capability, and enables the user to receive a call while listening to stereo music using earphones and surfing the Web. It has physical dimensions of 127.5×77.5×19.5 mm, and weighs 199 g. We studied three major areas in developing this pocket PC: (1) reduction of interference noise from the main control circuit board, (2) development of a compact wireless module, and (3) operability for data and voice communication.
