Decreasing energy consumption of devices is an important problem for modern Wi-Fi networks. To address this problem, the very first version of the Wi-Fi standard introduced a basic power saving mechanism. At the same time, the new IEEE 802.11ax and IEEE 802.11ba amendments describe modern power save mechanisms: target wake time (TWT) and wake-up radio ...
