What is the difference between blue-tooth and infrared?

Answer by  tamarawilhite (17883)

Blue-Tooth is a communication technology based on the radio frequency spectrum. It is used primarily in wireless communication devices like phone head sets and wireless keyboards. Infrared sensors use the infrared spectrum. It is only used in directional technologies like remote controls and sensor beams such as in security systems. Blue-tooth, however, can be used omni-directionally.

Blue-tooth is a form of wireless transmission or communication between devices using radio waves in the 2. 4GHz range. Infrared is a form of wireless communication using infrared light over short distances. Blue-tooth can be used through walls, but infrared can not.
