What is the DTIM Interval?
The DTIM Interval determines the number of AP beacons between each Delivery Traffic Indication Message (DTIM). This informs clients of the next window for listening to broadcast and multicast messages. When the AP has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Clients for that AP hear beacons and awaken to receive the broadcast and multicast messages.
