Abstract: A wrapper layer over a target interface receives requests from client devices over a different interface, converts the requests into a format that is compatible with the target interface, and transmits each converted request over the target interface for processing by a service. The wrapper layer also processes a request by a client device to subscribe to a certain type of update made via the target interface by verifying that the client device is authorized to access a resource associated with that type of update and creating a subscription that identifies the client device and the type of update. When the wrapper layer subsequently receives a request corresponding to that type of update, the wrapper layer matches attributes of the request to the subscription by the client device and transmits a message notifying the client device of the request.

Abstract: Described herein are techniques for integrating external sensors to an edge device, such as for ingesting data into a data intake and query system. The edge device has an internal message broker for communicating with internal (e.g., preconfigured, recognized) sensors, and an external message broker for communicating with external (e.g., customer-configured, otherwise unrecognized) sensors. The external message broker provides access to customer configuration of external sensors, but is logically quarantined from the internal message broker to prevent unwanted customer access to internal configurations. The internal and external message brokers interface only via a bridging service that transforms external sensor data into data based on customer-configurable transformations. The transformed data can be handled by the edge device and/or downstream components (e.g., a data intake and query system) in the same manner as internal sensor data.

Abstract: A radome cover design for a beamforming antenna is disclosed. In one aspect, a radome of a polymeric material having two thicknesses with a central thickness optimized for signal transmission at a frequency of interest is provided. Further, the radome is designed to be positioned at a fixed distance from an antenna array so as to provide protection for the antenna array yet still allow for optimal transmission of signals being steered at angles. Such radomes reduce significant signal loss and beam distortion while also being able to be manufactured at commercially reasonable costs.

Abstract: Supporting distributed massive multiple-input multiple-output (DM-MIMO) in a distributed communications system (DCS) is disclosed. The DCS includes multiple remote units each configured to communicate downlink and uplink radio frequency (RF) communications signals with a number of user equipment (UEs) at different UE locations in the DCS. Each remote unit includes multiple antennas, multiple RF chains, and an RF switch circuit configured to dynamically couple the RF chains to a subset of antennas in accordance to the UE locations such that the subset of antennas can be activated to concurrently radiate the downlink RF communications signals and absorb the uplink RF communications signals. By dynamically activating the subset of antennas in accordance to the UE locations, it is possible to optimize signal strength and channel quality for each UE in the DCS, thus making it possible to improve wireless data capacity of the DCS with negligible additional hardware cost.

Abstract: A communication circuit in a wireless communications system (WCS) is provided. The WCS employs self-interference cancellation (SIC) circuitry to suppress an interference signal(s) associated with an uplink communications signal(s) in a target uplink band(s). A communication circuit is employed to provide more accurate temporal and phase estimates about interference signal(s) in the target uplink band(s). The communication circuit utilizes an anchor downlink signal, which can be any of the downlink communications signals communicated in the WCS, to help determine an optimal phase shift for uplink communications signal(s) in the target uplink band(s). Accordingly, the SIC circuitry can suppress the interference signal(s) in the target uplink band(s) based on the optimal phase shift.

Abstract: Embodiments of the disclosure relate to supporting cooperative transmission in massive multiple-input multiple-output (MIMO) systems, such as a wireless distribution system (WDS). A WDS includes a plurality of remote units each defining a home coverage cell. A selected remote unit can coordinate with a neighboring remote unit(s) to help mitigate inter-cell interference for a selected client device(s) located in an overlapping coverage area between the home coverage cell of the selected remote unit and a neighboring coverage cell(s) defined by the neighboring remote unit(s). The selected remote unit receives channel-data information from the selected client device(s) and forms a first radio frequency (RF) beam based on the channel-data information to distribute a downlink signal(s) to the selected client device.

Abstract: Embodiments of the disclosure relate to a multi-source same-cell wireless distribution system (WDS) with dynamic source adaptation. In this regard, the WDS includes multiple remote units each configured to distribute a downlink communications signal having identical cell identification in a respective coverage area. The WDS includes a signal distribution circuit communicatively coupled to multiple signal sources. The signal distribution circuit can dynamically determine a selected coverage cell among multiple coverage cells having a client device load higher than a predefined load threshold. Accordingly, the signal distribution circuit can redistribute the defined source capacity of a selected signal source among the multiple signal sources exclusively to the selected coverage cell. By dynamically distributing more capacity to the selected coverage cell with higher client device load, it is possible to increase data throughput, thus helping to provide improved user experience in the selected coverage cell.

Abstract: Components, systems, and methods for reducing location-dependent destructive interference in distributed antenna systems operating in multiple-input, multiple-output (MIMO) configuration are disclosed. Interference is defined as issues with received MIMO communications signals that can cause a MIMO algorithm to not be able to solve a channel matrix for MIMO communications signals received by MIMO receivers in client devices. These issues may be caused by lack of separation (i.e., phase, amplitude) in the received MIMO communications signals. Thus, to provide amplitude separation of received MIMO communications signals, multiple MIMO transmitters are each configured to employ multiple transmitter antennas, which are each configured to transmit in different polarization states. In certain embodiments, one of the MIMO communications signals is amplitude adjusted in one of the polarization states to provide amplitude separation between received MIMO communications signals.
