Understanding DTIM Period

The delivery traffic indication message (DTIM) is an element included in some beacon frames. It indicates the client stations that are currently in low-power mode that have data buffered on the access point awaiting pickup. The DTIM period indicates how often clients serviced by the access point should check for buffered data awaiting pickup on the access point.

You specify the DTIM period in number of beacons. For example, if you set this value to 1, clients check for buffered data on the access point at every beacon. If you set this value to 10, clients check the access point on every tenth beacon. The default is two beacons. You can specify a value from 1 to 255 beacons.
