When searching the Internet for help solving various issues involving networking my devices via Bluetooth and/or Wi-Fi it seems that the terms "ad-hoc network" and "personal area network" (PAN) are sometimes used interchangeably.
Do they actually mean the same thing?
Or is one properly a subset of the other?
Or is PAN standardized and ad-hoc not?
Or is one term preferred by one or more companies, OSes, communities?
