A personal area network (PAN) provides networking needs around an individual.
An example of a PAN is where a smartphone, smartwatch, tablet, and laptop all connect and share data without the need to connect to an access point or other non-Microsoft network services. PAN networks typically use Bluetooth® to communicate because it provides a low-power, short-range data-sharing capability. The network standards associated with a PAN are Bluetooth and IEEE 802.15.
