Options are :

  • The client and the AP may use different transmission rates, but the AP determines the data rate used for each client station BSS.
  • The client and the AP can use a different transmission rates, but the customer determines the data rate that it uses and the data rate used by the AP when communicating with the customer.
  • During the connection the client and the AP agree to use thesame transmission speed, but either station may request a change, at any time after the association.
  • Customer and each AP to select the optimal data rate used independently of each other, based on their own measurements of the RF link.
  • None

Answer :Customer and each AP to select the optimal data rate used independently of each other, based on their own measurements of the RF link.
