There is a need for a device that is capable of sending unique forms of data in an intelligent manner as to have no limitations regarding its functionality. An infrared kiosk that would allow consumers to download news, pictures, maps, schedules or any other forms of media to their laptop or personal digital assistant (PDA) regardless of environment via the infrared port would meet such requirements. Analysis of field data on the topic of infrared and its universal protocol provided by the Infrared Data Association (IrDA) was understood and applied in the design. Deep knowledge regarding modulating and demodulating of pulse signals has led to a prototype construction of an infrared transceiver with capabilities reaching the maximum transfer rate of serial infrared (115kbps). Main advantages were that widely available and cost effective components were used for this prototype. Finally, this transceiver is very adaptable as it can be implemented in any infrared project using any serial microcontroller.
