Enterprise WLAN Planning and Design

Which of the following statements about PoE power supplies is false?

Choose two
  • A Wi-Fi 6 APs must use 802.3bt power supply.
  • B PoE++ technology complies with IEEE 802.3bt, which provides a maximum of 81.6 W power to PDs.
  • C PoE technology complies with IEEE 802.3af, which provides a maximum of 12.95 W power to PDs.
  • D PoE+ technology complies with IEEE 802.3at, which provides a maximum of 25.5 W power to PDs.
Explanation

Wi-Fi 6 does not inherently require IEEE 802.3bt; the PoE standard required depends on the specific AP and its feature set. IEEE 802.3bt Type 4 provides up to approximately 71 W at the powered device, rather than 81.6 W. IEEE 802.3af and IEEE 802.3at provide up to 12.95 W and 25.5 W, respectively, at the powered device.
