Abstract :
Personal communication and computing devices have become omnipresent: cellular phones, PDAs, MP3 players, still and video cameras. Characteristics shared by all these devices include a shrinking size and expanded performance and functionality. All can be carried by a person on a single belt. However, a suitcase is required for all the chargers, as well as the cables to connect to PCs and all the cradles, earplugs etc. The proliferation of such devices has also resulted in a proliferation of standards: TDMA, CDMA, GSM, GPRS, to name a few in cellular communication, Wi-Fi and Bluetooth. The same can be said of audio, image and video standards.
