  C. The DCF and EDCA coordination functions require backoff algorithms
  D. WLAN devices cannot detect collisions and must receive positive frame acknowledgment.
  E. WLANs rely on the CSMA/CD protocol and must wait a collision detection period after each frame is transmitted.
  C. The DCF and EDCA coordination functions require backoff algorithms
  D. WLAN devices cannot detect collisions and must receive positive frame acknowledgment.
