IEEE 802.15.4, which is the standard for low-rate wireless personal area networks (LR-WPANs), uses Carrier Sense Multiple Access with Collision Avoidance (CSMA-CA) for channel access. This method helps in reducing the chances of collisions on the network by first sensing the channel before transmitting data.
