The IEEE (Institute of Electrical and Electronics Engineers) have
defined a number of standards for LANs (Local Area Networks). The IEEE 802
standard describes the lower two layers in the OSI (Open Systems
Interconnection)
OSI 7-layer model IEEE 802 standard 7. Application layer 6. Presentation layer 5. Session layer 4. Transport layer 3. Network layer 2. Data Link layer 802.2 LLC (Logical Link Control) sublayer 802.1 Management 802 Overview and Architecture 802.11 MAC (Medium Access Control) sublayer 1. Physical layer 802.11 PHY (Physical) layer 802.11 PLCP (Physical Layer Convergence Protocol) sublayer 802.11 PMD (Physical Medium Dependent) sublayer
