IEEE 802.15 is the working group 15 of the IEEE 802 which specializes in Wireless PAN standards. It includes four task groups (numbered from 1 to 4):
- Task group 1 (WPAN/Bluetooth) deals with Bluetooth, having produced the 802.15.1 standard, published on June 14, 2002. It includes a medium access control and physical layer specification adapted from Bluetooth 1.1.
- Task group 2 (Coexistence) deals with coexistence of Wireless LAN (802.11) and Wireless PAN.
- Task group 3 is in fact two groups: 3 (WPAN High Rate) and 3a (WPAN Alternate Higher Rate), both dealing with high-rate WPAN standards (20 Mbit/s or higher).
- Task group 4 (WPAN Low Rate) deals with low rate but very long battery life (months or even years). The first edition of the 802.15.4 standard was released in May 2003. In March 2004, after forming Task Group 4b, task group 4 put itself in hibernation. The new Task group 4b aims at clarifying and enhancing specific parts of the Task Group 4 standard. The ZigBee set of high level communication protocols is based upon the specification produced by this taskgroup.

Electronics Topics
The field of electronics is the study and use of systems that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the fields of electronic engineering, and the hardware design side of computer engineering. The study of new semiconductor devices and their technology is sometimes considered as a branch of physics.
