Open System Interconnection Reference Model

The BayStack 660 Wireless LAN products conform to the Open System 
Interconnection (OSI) reference model for data communications. The lower two 
layers of the seven layer model are implemented as illustrated in 

Figure 1-3

 and 

outlined following the illustration.

Figure 1-3.

BayStack 660 Wireless LAN Technology 
and the OSI Reference Model

 

The MAC portion of the Data Link layer interfaces to the higher level software 
through the network drivers. The IEEE 802.11 protocol has a four-part packet 
handshake to assure fair and controlled access to the media. It provides virtual 
collision detection and enhanced error detection and retransmission.
