Wireless PAN technologies utilize both radio frequencies and infrared light, depending on the application.
The IEEE 802.15 standards working group focuses on the development of standards for wireless PANs and coordinates with other standards, such as 802.11 wireless LANs.
The 802.15 standards working group contains the following elements:
802.15.1— This working group, Task Group 1, defines a wireless PAN standard based on Bluetooth v1.1 specifications, which uses frequency hopping spread spectrum (FHSS) and operates at up to 1 Mbps. The 802.15 group published 802.11.1 in June of 2002, and it is meant to serve as a resource for developers of Bluetooth devices.
802.15.2— The group responsible for this standard, ...
