WLAN power saving
Example: The frequency of scanning is having major impact to terminals stand-by times, so it's important to avoid performing unnecessary scans.
Main tools to improve WLAN power efficiency is on the network side.
- Office WLAN network should support Unscheduled Automatic Power Save Delivery (U-APSD) support. U-APSD is a power save scheme optimized for real-time applications transferring full-duplex data over WLAN.
- Should use the proxy ARP to help to limit the bandwidth lost to multicast and broadcast traffic.
Important thing is to avoid frequent scanning, use correct DSCP (DiffServ Code Points) settings. WLAN is also very fast link so applications should try to send/receive large amounts data to reduce per byte overhead
