How data link layer works in wireless network?

In a wireless network, the data link layer manages the communication between devices over the radio frequency medium. It is responsible for framing data packets, addressing, and error detection and correction. This layer utilizes protocols like IEEE 802.11 (Wi-Fi) to handle medium access control (MAC), which ensures that multiple devices can share the same frequency without data collisions. Additionally, the data link layer establishes a reliable link by managing signal quality and retransmissions when necessary.
