Bluetooth and IrDA, two solutions for wireless communication. Application: IrDA modem implemented in Verilog Hardware Description Language.

The project analyses the two wireless technologies that are entering the market, both individually and together in an attempt to underline their advantages and disadvantages. The first part describes the Bluetooth technology in more general terms. It will explain what Bluetooth is, how it can affect us in various ways, what different applications and products exists. The second part deals with infrared standard technology, also known as IrDA. The use of infrared techniques for data communications has been around for several years, and by 1993 several commercial products were available with this capability. However, each company has tended to have its own infrared standard, and although devices from the same manufacturer could communicate with each other, competing systems tended not to be interoperable. The third part deals with the comparison between the two technologies, pointing out their best uses and features in specific applications. The application is a implementation of an IrDA modem, at the physical layer of the technology. It facilitates the data transfer by modulating the serial signal and preparing it for transfer via an infrared beam. At the other end it demodulates the signal received from the infrared beam and recovers the serial data.
