Lecture description
Wi-Fi 6 has made Wi-Fi more attractive for IoT. Features such as OFDMA enhance the spectrum utilization in Wi-Fi networks in favor of low-data-rate IoT clients, while Target Wake Time offers a new power save mechanism for battery-operated devices.
With TWT clients can enjoy long idle times, while maintaining connection to the Access Point. Yet, when attempting to utilize TWT in commercial Wi-Fi stacks, interoperability issues occur at different networking protocol layers. Without addressing such issues, Wi-Fi extended power saving with TWT is not able to reach its full potential.
We will focus on certain features of wireless and TCP/IP networking protocol stacks that can enable TWT and extended sleep, allowing Wi-Fi IoT devices to enjoy robust and resilient connectivity at the highest possible energy efficiency.
