Abstract

This study will brief the readers about the physical layer for a infrared communication system for portable devices, it will discuss the infrared physical layer from few perspectives, e.g: power consumption, link distance, radiation pattern etc. Few vital mathematics equations will be outline briefly along the discussion. It then follows by the infrared emitter and detector analysis. Lastly, it will discuss some relevent method to increase the link distance for more effective system. Infrared light, commonly referred to as “IR”, is a common, easy-to-use, low power and low-cost media to transmit information. Among the few “wireless” communication choices, IR has the significant advantage of compatibility with hundreds of millions of electronic devices with IR ports (i.e., laptop PCs, PDAs). The vast majority of IR-capable devices are compatible with a set of standards established by the Infrared Data Association, or IrDA®. These standards include guidelines for implementing the IR Physical Layer (IrDA Serial Infrared Physical Layer specification), ensuring that IR communication can be established through free space between two dissimilar devices.
