FEATURE: Target Wake Time (TWT)
● Initially introduced in 802.11ah-2016 to help conserve
power for IoT applications.
● OFDMA consumes more power and hence we need
power saving mechanisms with 802.11ax
● Clients can request a specific wake-up time thereby
conserving battery life.
● AP can better manage wake-up time for connected
clients, thereby reducing contention and increasing
airtime efficiency
● With legacy standards, all devices have to wake up at the
same time (DTIM)
● Also supported in 2.4 GHz.
● Up to 67% lower power consumption!
