Bluetooth And Infared 

With new electrical devices being produced every day, the problem of connecting things is becoming more and more complex in nature.  The system that comprises computers and other electronics makes use of varieties of wires, cables, etc. 

These parts will communicate through light beams, lasers, radio signals, and infrared.  The problem however, is the devices and technology is often the connection between each component.  Therefore, most
electronic systems aren't used to their full extent due to the problems and imperfections.

To help simplify things, a solution was created - the solution of Bluetooth.  Bluetooth is wireless and automatic, offering users a variety of features that have simplified the art of connection.  Bluetooth has revolutionized the standard methods of connecting things to enabling almost anything to be connected to a single system.

Aside from Bluetooth, there are other ways of connecting wireless devices.  One example of such is the IR or infrared.  Infrared allows low frequency light waves to transmit signals to another component. This technology is easy to create and the cost of putting the IR device into a system is rather low.

Infrared technology is a one to one process.  Due to the limitation, you may only send signals from one device to another, similar to a television set and remote control.  You can only transmit signals between the two although not with a seperate system.

Aside from the fact that these two natures of infrared are obstacles to acquiring results, these same qualities have worked in advantage to the
connection.  Infrared devices need to be lined up directly, meaning too little interference can occur between the transmitters and receivers.

The technology behind Bluetooth works by transmitting signals through low frequency radio signals.  The path of communication is working on 2.45 GHz, which is the same frequency band used in ISM devices.
