802.15 standards
Many of the protocols and network models described in this chapter are based upon or have a foundation in the IEEE 802.15 working groups. The original 802.15 group was formed to focus on wearable devices and coined the phrase personal area network. The group's work has expanded significantly and now focuses on higher data rate protocols, meter to kilometer ranges, and specialty communications. Over one million devices are shipped each day using some form of 802.15.x protocol. The following is a list of the various protocols, standards, and specifications that the IEEE maintains and governs:
- 802.15: WPAN definitions
- 802.15.1: Original foundation of the Bluetooth PAN
- 802.15.2: Coexistence specifications for WPAN and WLAN for Bluetooth
- 802.15.3: High data rate (55 Mbps+) on WPAN for multimedia
- 802.15.3a: High-speed PHY (physical layer) enhancements
- 802.15.3b: High-speed MAC enhancements
- 802...
