Why do wireless networks not use CSMA/CD to detect and avoid network collisions?
What will be an ideal response?
Modern wired networks use switches running in full-duplex mode, so they don't have to worry about collisions. In this environment, CSMA/CD is disabled when using full-duplex. Wireless networks don't have this luxury for two reasons. First, radio is a half-duplex transmission method, since a wireless device cannot listen and send at the same time. Secondly, there are times where wireless clients may not know about the existence of another client due to signal strength. Wireless networks, for those reasons, use CSMA/CA to avoid collisions.
