3.2.1 AP Based Roles

  • A CTS frame destined to our own MAC-Address is sent without an RTS frame preceding it (CTS-to-Self)
  • Other wireless devices in the network will refrain from accessing the medium for the duration mentioned in the CTS frame and wait to access the medium, while in fact the AP based role is leaving the channel as illustrated by Figure 3-1 below:
