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.
