Detailed explanation-1: -Which of the following specifies a set of media access control (MAC) and physical layer specifications for implementing WLANs? Explanation: IEEE 802.11 is a set of media access control and physical layer specification for implementing WLAN computer communication.
Detailed explanation-2: -IEEE 802.11 is part of the IEEE 802 set of local area network (LAN) technical standards, and specifies the set of media access control (MAC) and physical layer (PHY) protocols for implementing wireless local area network (WLAN) computer communication.
Detailed explanation-3: -The 802.11 protocol operates in two very specific layers of the OSI model; LAYER 1 and LAYER 2.
Detailed explanation-4: -802.11a uses radio frequencies in the 5 GHz band and supports theoretical throughput of up to 54 Mbps. The standard uses the same base protocol as the original 802.11 standard, but uses orthogonal frequency-division multiplexing (OFDM). Also known as IEEE 802.11a-1999.
Detailed explanation-5: -802.11 use either frequency hopping spread spectrum (FHSS) or direct sequence spread spectrum (DSSS). IEEE 802.11a operates in the 5GHz band and provides data rates up to 54Mbps. 802.11a uses an orthogonal frequency division multiplexing (OFDM) encoding scheme.
