Power Saving Technologies

•Power Efficiency
–Use versatile PMU, Power Management Unit
–Use efficient and power manageable PA, Power Amplifier
–Use efficient and power manageable CPU, Center Process Unit
•Power Management
–Add Power-down (or Sleep) mode in addition to Continuously-active mode
–Per IEEE802.11 Standard, replace Continuously-active mode by Power-saving (or Standby) mode, using PS-Polling approach
–Per IEEE802.11e Standard, replace Continuously-active mode by a more efficient Power-saving (or Standby) mode, using Scheduled or Unscheduled Automatic Power Save Delivery approach
