Abstract: A system and various methods to implement a Digital Twin with a low power Wi-Fi device is disclosed. The low power Wi-Fi device seeks a Digital Twin at the time of commissioning to serve as its proxy node while it is in sleep mode. Additionally, techniques to address the situation where the Digital Twin becomes unavailable are also disclosed. Finally, techniques to create and update a chain of Digital Twins are also disclosed.

Abstract: Methods and Wi-Fi devices that utilize the target wait time (TWT) feature of the Wi-Fi specification are disclosed. These 5 methods reduce power consumption by selectively listening to only a portion of the beacons that are transmitted by the access point. In one scenario, the Wi-Fi device only listens to one beacon per TWT wake interval. In another embodiment, the Wi-Fi device may have knowledge of the application that is being executed, such as its allowable latency. The Wi-Fi device may use this allowable latency to determine which when to exit low power mode to receive a beacon. Further, mechanisms to ensure that the connection between the Wi-Fi device and the access point are also disclosed.
