To be exact, IEEE 802.11 releases use CSMA/CA (Collision Avoidance) instead of CSMA/CD (Collision Detection) which is used in wired networks. OFDM, on the other hand, is just an advanced digital modulation scheme which divides the data stream … WebSep 11, 2024 · It is used in wireless and wired technology. CSMA/CA is a protocol that operates in the data link layer of the OSI model. The access method used by IEEE 802.11 Wi-fi in CSMA/CA. Let us have a look on Algorithm and flowchart of CSMA/CA for more detail understanding the concept: Algorithm. The algorithm of CSMA/CA is as follows:
