摘要

The internet has been the mantra in last decade and digital convergence is the latest talk on the tech streets. Features that once clearly discerned a mobile phone from a PDA or a PDA from a laptop are being replaced with multi-functional overlapping features and there is a growing need for wireless access and interoperability. Infrared communications has been addressing these needs for quite some time. The technology has matured through standardization efforts of IrDA (Infrared Data Association) and is widely used in PDAs, mobile phones, laptops, printers and digital cameras to name a few. This paper explores some new application scenarios for an IrDA transceiver. The first part of the paper describes a reference architecture for using infrared wireless communication for MP3 file exchange and the various possible user models. The second part of the paper discusses various configurations for implementing an ambient light detection scheme using IrDA transceivers, to turn off the backlighting of a LCD panel of a PDA or mobile phone in the presence of ambient light. The third part of the paper discusses various techniques of enabling extended link distance operation of IrDA transceivers for toy and remote control applications.
