Individual specifications in the 802 series are identified by a second number. 5 is the Token Ring specification. Other specifications describe other parts of the 802 protocol stack. 2 specifies a common link layer, the Logical Link Control (LLC), which can be used by any lower-layer LAN technology. 1. 1Q). 2/LLC encapsulation. 11 MAC and two physical layers: a frequency-hopping spread-spectrum (FHSS) physical layer and a direct-sequence spread-spectrum (DSSS) link layer. 11 added additional physical layers.
When robust security network protocols are in use, association is a precursor to authentication. Prior to the completion of authentication, an access point will drop all network protocol traffic from a station. Reassociation When a mobile station moves between basic service areas within a single extended service area, it must evaluate signal strength and perhaps switch the access point with which it is associated. Reassociations are initiated by mobile stations when signal conditions indicate that a different association would be beneficial; they are never initiated directly by the access point.
11 provides nine services. Only three of the services are used for moving data; the remaining six are management operations that allow the network to keep track of the mobile nodes and deliver frames accordingly. The services are described in the following list and summarized in Table 2-1: Distribution This service is used by mobile stations in an infrastructure network every time they send data. Once a frame has been accepted by an access point, it uses the distribution service to deliver the frame to its destination.
