摘要： A communication system that includes a cloud server that obtains first sensor data associated with a defined indoor area and second sensor data associated with each of a plurality of optical nodes in defined indoor area. The plurality of optical nodes includes a master communication device, a plurality of optical routing devices, and one or more service communication devices. The cloud server further obtains location coordinates of each of the plurality of optical nodes. The cloud server then causes the master communication device to form a laser beam-based wireless communication network in the defined indoor area. The laser beam-based wireless communication network is one of a Laser Beam Mesh Network (LBMN) or a Laser Beam Cascaded Network (LBCN).

摘要： The disclosure provides for a method for reacquiring a communication link between a first communication device and a second communication device. The method includes using one or more processors of the first communication device to receive historical data related to the first communication device and an environment surrounding the first communication device. The one or more processors are then used to determine one or more trends in the historical data related to fading of the communication link. Based on the one or more trends, the one or more processors are used to determine a starting time and an initial search direction for a search for the communication link. The one or more processors then execute the search at the starting time from the initial search direction.

摘要： Disclosed is a SmartDust system for contactless digital controlled serialized analog processing of analog values received from an object. The SmartDust system includes a hub unit and at least one electronic circuitry capacitive coupled to the hub unit. The hub unit includes an oscillator for generating a frequency, and a first electrode connected to the oscillator to emit the frequency as an alternating electric field. The electronic circuitry stores and performs switching instructions and the digital logic operations. The electronic circuitry receives analog values and generate sampled and processed analog values. The electronic circuitry provides the processed values to external components. The hub unit includes a controller for providing the switching instructions and the digital logic operations to the electronic circuitry, and a modulator for modulating the alternating electric field with the switching instructions and the digital logic operations.

摘要： A Reconfigurable Intelligent Surface (RIS)/Light Fidelity (LiFi) rack communication system includes a rack that includes a computing device, a LiFi device that transmits first light-modulated data, and a RIS system. The RIS system includes a RIS device that directs the first light-modulated data transmitted by the LiFi Device at the computing device, and a RIS control subsystem that is coupled to the at least one RIS device. The RIS control subsystem determines a first signal integrity of the first light-modulated data received by the computing device via the RIS device when the RIS device includes a first configuration, and reconfigures the RIS device with a second configuration such that the first light-modulated data received by the computing device via the RIS device includes a second signal integrity that is greater than the first signal integrity.
