Line 12:
DCF includes a positive acknowledge scheme, which means that if a frame is successfully received by the destination it is addressed to, the destination needs to send an ACK frame to notify the source of the successful reception.
 
DCF does not solve the [[Hidden node problem|hidden terminalnode]] and/or exposed terminal problem completely, it only alleviates the problem through the use of RTS and CTS, and recommends the use of a larger carrier sensing range.
 
DCF is defined in the IEEE 802.11 standard and is the de facto default setting for Wi-Fi hardware.
