A personal area network (PAN) connects devices within an individual's immediate vicinity, such as computers and phones. There are two types of PANs: wired and wireless. Wired PANs connect devices physically using cables, while wireless PANs connect devices through infrared, Bluetooth, or home radio frequency without cables. Wireless PANs are established automatically once devices are within range of each other. PANs provide quick and easy data transfer but have limited range and compatibility between devices. They are used in applications like healthcare, transportation hubs, education, the military, homes, and offices.
