stack
The IEEE 802 standards "only" explain physical layer (PHY) and MAC sublayer in
the OSI Model.
Several IEEE 802 standards that are often mentioned in publications are
listed below:
IEEE
802.11a : Wireless LAN Medium Access Control (MAC) and Physical
Layer (PHY) Specifications � High-speed Physical Layer in the 5
GHz band. The implementation of this standard is also known as
Wireless A.
IEEE
802.11b : Wireless LAN Medium Access Control (MAC) and Physical
Layer (PHY) specifications � Higher-speed Physical Layer (PHY)
extension in the 2.4 GHz band. The implementation of this standard
is popularly known as Wi-Fi or
Wireless B.
IEEE
802.11g : Wireless LAN Medium Access
Control (MAC) and Physical Layer (PHY) specifications � Further
Higher-Speed Physical Layer Extension in the 2.4 GHz Band. The
implementation of this standard is also known as Wireless G.
IEEE
802.15.1 : Wireless Medium Access Control (MAC) and Physical Layer
(PHY) Specifications for Wireless Personal Area Networks (WPANs).
This standard is based on Bluetooth
specification.
IEEE
802.15.3 : Wireless Medium Access Control
(MAC) and Physical Layer (PHY) Specifications for High Rate
Wireless Personal Area Networks (HR-WPANs).
IEEE
802.15.4 : Wireless Medium Access Control
(MAC) and Physical Layer (PHY) Specifications for Low Rate
Wireless Personal Area Networks (LR-WPANs). This standard
refers to ZigBee specification.
IEEE 802.16 : Air Interface for Fixed Broadband Wireless Access
Systems. The implementation of
this standard is known as WiMAX.
