What is Personal Area Network (PAN)?A personal area network (PAN) is the interconnection of information technology
devices within the range of an individual person, networks often cover an area of 30 feet.
It could be wired or wireless
What is Infrared?It allows the devices to communicate via short-range wireless signals.
