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.
