Wmm power save mode arris11/15/2022 ![]() ![]() To take advantage of WMM-Power Save functionality, both the Wi-Fi client and the access point need to be Wi-Fi CERTIFIED™ for WMM-Power Save. Furthermore, Wi-Fi CERTIFIED™ for WMM-Power Save devices will be able to operate in any Wi-Fi network and coexist with 802.11 legacy power-save mechanisms. WMM-Power Save certification indicates interoperability across vendors. Certification started in December 2005 and is open to any Wi-Fi device certified for WMM. The Wi-Fi Alliance has announced a new certification program for WMM-Power Save driven by the market demand for converged Wi-Fi mobile devices that support voice applications. With WMM-Power Save, the same amount of data can be transmitted in a shorter time and using fewer frames, while allowing the Wi-Fi device to remain longer in a low-power, "dozing" state. WMM-Power Save uses mechanisms included in the Institute of Electrical and Electronics Engineers (IEEE) 802.11e amendment and is an enhancement of IEEE 802.11 legacy power save, which was designed for data applications. ![]() WMM-Power Save has been optimized for mobile devices running latency-sensitive applications such as voice, audio, or video, but can benefit any Wi-Fi device. It is an addition to WMM, the technology that enables Quality of Service (QoS) functionality in Wi-Fi networks by prioritizing traffic from different applications. WMM (Wi-Fi Multimedia) Power Save extends the battery life of Wi-Fi devices by increasing the efficiency and flexibility of data transmission. Wi-Fi mobile devices require advanced power-save mechanisms to offer a rich user experience for voice, audio, and video applications. ![]() Wi-Fi CERTIFIED™ for WMM®-Power Save: Support for Advanced Power Save for Mobile and Portable Devices in Wi-Fi® Networks (2005) ![]()
