Chapter 4. IEEE 802.11's MAC Sub-layer Protocol—Frames, etc.

While the Physical layer options discussed in Chapter 3 are of fundamental importance (and are very tangible to the end user, because they are directly related to perceivable characteristics such as the performance of the WLAN), the unifying feature that all IEEE 802.11-based WLANs have in common is their MAC sub-layer protocol. In contrast to the PHY protocol(s), the MAC sub-layer protocol is virtually invisible to end users, except when they initially configure their WLAN adapter.

In this chapter, we describe the MAC sub-layer protocol that has been developed for IEEE 802.11-based WLANs. The discussion in this chapter is based on the MAC sub-layer protocol that was specified in the ...
