QUESTION 17 What is true regarding the IEEE 802.11 WLAN standard? a. WLANS operate in the licensed operating frequencies, therefore data collisions do not occur. b. Since 802.11 WLANS implement DSSS and OFDM, there is no need for a collision avoidance mechanism. c. The 802.11 Point Coordination Function (PCF) is an optional feature that enables the WLAN to operate as a centralized access network. d. 802.11 networks only implement centralized access using access points (APs)
