This disclosure describes systems, methods, and devices related to enhanced channel efficiency. A device may enable utilization of a secondary channel within a Wi-Fi network when a primary channel is engaged. The device may monitor a status of the primary channel while it is busy. The device may assess a presence of energy in the primary channel using Clear Channel Assessment (CCA) during a receiving mode. The device may provide the status of the primary channel via a block acknowledgment during frame exchanges on the secondary channel when the primary channel is determined to be idle. The device may instruct a switch back to the primary channel through a broadcast frame or a unicast frame.
