A dental office provides a WLAN in the waiting area for patients to access the Internet. The WLAN is equipped with a wireless router that connects to the Internet through a cable connection. Which data transmission mode is used by wireless devices?

  • simplex
  • half-duplex
  • full-duplex
  • multi-duplex

Explanation: WLAN standards use carrier sense multiple access with collision avoidance (CSMA/CA). Each wireless device that transmits data includes in the frame the time duration that it needs for the transmission. All other wireless devices receive this information and know how long the medium will be unavailable. Therefore, wireless devices operate in half-duplex mode.
