Abstract: A system and method enhances Wi-Fi protocol by transmitting an Internet-of-Things (IoT) notification map designated for an IoT device. The IoT notification map having format of at least part of a beacon frame and be included in an IoT beacon frame that, when transmitted by at least one router, causes the IoT device to perform an operation indicated in the IoT notification map. The at least one router may be part of the router cluster designated for the IoT device. The router cluster may include a subset of a plurality of routers within a geographical area associated with a location of the IoT device.

Abstract: This application is directed to an electronic device that acts as a bridge between a remote system and one or more other electronic devices. For instance, the electronic device may establish a first network connection using one or more network interfaces and a second network connection using the one or more network interfaces. In some instances, the first network connection includes a wireless local area network and the second network connection includes a low-power wide-area network. The electronic device may then receive data from the remote system over the first network connection, where the data represents a command for an additional electronic device. Using the data, the electronic device may transmit a data packet to the additional electronic device over the second network connection. The data packet may represent at least an identifier of the additional electronic device and the command.
