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.

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: The present technology may be directed a system for determining an angle and distance between a positioning node and secondary device using a plurality of acoustic transmitters to transmit acoustic ranging signals that are modulated using ranging sequences, respectively. The system includes an acoustic receiver to detect the acoustic ranging signals, and a signal processor to calculate times of arrival and a plurality of aliased angles of arrival of the acoustic ranging signals. An anti-aliasing module may select an angle of arrival from the calculated plurality of aliased angles using the times of arrival of the acoustic ranging signals. A time of flight may be calculated from a comparison of times of arrival for radio signals and the acoustic signals. The time of flight may be used to calculate the distance between the positioning node and secondary device.

Abstract: A mobile device is described for tracking an object and sensing an environment of the object. The mobile device includes a circuit board that is loaded with radio frequency (RF) transmitters and receivers for finding the device position and communicating data about the device, the ambient environment of the device, and/or the position of the device. Sensor on the device may measure data about the device and about the ambient environment of the device. Flexible antennas increases the effective volume for a plurality of antennas for increased range and/or reduced power. An adjustable impedance circuit provides for real-time tuning and impedance matching of the antennas.
