        **What power saving mechanisms are introduced in IEEE 802.11ax?**

        802.11ax introduces Target Wake Time (TWT) and enhanced Power Save Mode (PSM) to reduce energy consumption.

        **How does Target Wake Time (TWT) improve power saving?**

        TWT schedules specific wake times for devices, allowing them to sleep longer and reduce idle listening.

        **What is the difference between individual and broadcast TWT?**

        Individual TWT is negotiated between AP and a single client; broadcast TWT schedules wake times for multiple clients.

        **Does 802.11ax support legacy power save methods?**

        Yes, it supports traditional Power Save Mode (PSM) for backward compatibility.

        **How does TWT reduce contention and improve efficiency?**

        By scheduling transmissions, TWT minimizes simultaneous wake-ups and channel contention among devices.

        **Can TWT be used in uplink and downlink transmissions?**

        Yes, TWT schedules wake times for both uplink and downlink data transmissions.

        **How does 802.11ax support power saving in multi-user scenarios?**

        It uses TWT along with OFDMA and MU-MIMO to efficiently schedule multi-user transmissions and reduce device active time.

        **What role does the AP play in power saving for 802.11ax?**

        The AP coordinates TWT schedules and buffers data during client sleep periods to optimize battery life.

        **How does 802.11ax handle broadcast and multicast traffic in power saving?**

        Broadcast and multicast frames are delivered during scheduled Delivery Traffic Indication Map (DTIM) intervals.

        **Can devices wake up on-demand outside scheduled TWT?**

        Yes, devices can request unscheduled service but it may reduce power savings.

        **How does 802.11ax power saving differ from 802.11ac?**

        802.11ax adds TWT and more efficient multi-user scheduling compared to the basic PSM in 802.11ac.
