| In minimum power save mode, station wakes up every DTIM to receive beacon. Broadcast data will not be |
| lost because it is transmitted after DTIM. However, it can not save much more power if DTIM is short |
| for DTIM is determined by AP. |
| In maximum power save mode, station wakes up every listen interval to receive beacon. Broadcast data |
| may be lost because station may be in sleep state at DTIM time. If listen interval is longer, more power |
| is saved but broadcast data is more easy to lose. |
