==CS ''versus'' CA==
If [[Carrier sense multiple access]] (CSMA) ''"...is a probabilistic Media Access Control (MAC) protocol in which a node verifies the absence of other traffic before transmitting on a shared transmission medium"'', then what does /CA add? This CSMA/CA article currently states that ''"...carrier sensing is used, but nodes attempt to avoid collisions by transmitting only when the channel is sensed to be "idle"..."'' - but surely this is true of CSMA/CD too?

== Reason for using CSMA/CA over CSMA/CD ==
The article says that CSMA/CA is used in radio networks because CSMA/CD cannot solve the hidden terminal problem. While this is correct, the more important reason is imho that in radio networks, nodes are typically not able to transmit and receive at the same time (cf. also section "CSMA/CA does not use RTS/CTS"). Thus, it is typically not possible to implement CSMA/CD in a wireless network. This should imho be mentioned in the article.[[Special:Contributions/93.135.120.181|93.135.120.181]] ([[User talk:93.135.120.181|talk]]) 13:52, 6 October 2013 (UTC)
