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