This draws out a comparison Between the 2 most common Personal Area Networking ( PAN ) solutions commonly used. They are 1. BlueTooth and 2. InfraRed
* Both BlueTooth and InfraRed are used to communicate within short distances ( i.e. PAN ).
* BlueTooth used in mobile devices have a range of about 10 metres and can communicate with another BlueTooth capable device within a circle of 10 metre radius.
* InfraRed needs a direct line of contact. It means that 2 InfraRed Enabled devices can communicate with each other only if they are in a same line. The speed of data transfer decreases with increasing distance.
* With a InfraRed Device and proper Software to support, one can control other devices like a TV set or a DVD player. This cannot be achieved using a BlueTooth enabled device unless there is a BlueTooth adapter available with the other device.
Both these systems are energy efficient and uses very less power. But due to the reason that a BlueTooth device deosn't require line-of-sight contact, BlueTooth is getting more popular.
