When a user is making a voice or video call on a user device over a wireless local area network (WLAN), the characteristics of a WLAN call can cause high power consumption on the user device, latency, and poor transmission which leads to an unfavorable quality of service. The user device can optimize the WLAN for voice and video calls by detecting timing information of a WLAN call and then optimizing the device’s software and hardware during the WLAN call. The device may use a target wakeup time (TWT) protocol to reduce power consumption. The device may reduce the number of antennas, the channel bandwidth, or the power mode of one or more radios to reduce power consumption. To reduce latency, the device may adjust power save parameters, scanning and roaming operations, and cap the number of retries to send packets. The device may improve transmission reliability by using a medium physical layer (PHY) rate and by enabling request to send/clear to send (RTS/CTS) when communicating with a WLAN access point (AP).
