Power Management Approach
{"Image DocumentName": "Power Management Approach", "Image ImageDescription": "Allow idle stations to go to sleep. Station\u2019s power save mode stored in AP. APs buffer packets for sleeping stations. AP announces which stations have frames buffered. Traffic Indication Map (TIM) sent with every Beacon. Power saving stations wake up periodically. Listen for Beacons. Time Synchronization Function (TSF) assures AP and power save stations are synchronized. Stations will wake up to hear a Beacon. Synchronization allows extreme low power operation. TSF timer keeps running when stations are sleeping. 6: Wireless and Mobile Networks.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
