A wireless personal area network (WPAN) is a PAN carried over a low-powered, short-distance wireless network technology such as IrDA, Wireless USB, Bluetooth or Zigbee. The reach of a WPAN varies from a few centimeters to a few meters.
Personal area networks enable data exchange between small devices and give users the ability to set up an ad hoc network. The connection can be wireless or wired and is limited to a few meters. Depending on the technology used, a line-of-sight connection is also required.
A personal area network can be wireless or wired. A wired PAN is linked to computers by cables. A wireless PAN, or WPAN, uses Bluetooth to transfer data. The reach of a WPAN can range from a few centimeters to a few meters. It can be used to connect to higher-level networks and the Internet.
