Which standard defines the specifications for wireless personal area networks (WPAN)?

802.11
802.15
802.16
802.22

The correct answer is: 802.15

The standard that defines the specifications for wireless personal area networks (WPAN) is indeed 802.15. This standard is specifically designed for short-range communication between devices, typically covering distances of up to about 10 meters. It encompasses various protocols like Bluetooth and Zigbee, which are commonly used in personal area network applications for connecting devices such as smartphones, computers, and wearable technology. The other standards mentioned serve different purposes: 802.11 pertains to wireless local area networks (WLAN) commonly known as Wi-Fi, allowing for broader coverage and higher data rates; 802.16 refers to wireless metropolitan area networks (WMAN), which aim to provide wireless broadband access in a larger geographical area; and 802.22 is designed for wireless regional area networks (WRAN), extending connectivity to a rural setting by utilizing unused radio frequencies in the TV broadcast spectrum. Each of these standards addresses different networking needs, but 802.15 specifically targets the requirements and communication patterns typical in personal area networks.
