Abstract: Distributed communications systems (DCSs) supporting virtualization of remote units as citizens band radio service (CBRS) devices (CBSDs) are disclosed. In examples discussed herein, the DCS includes a routing circuit that is coupled to a number of remote units configured to communicate a downlink communications signal(s) and an uplink communications signal(s) in one or more CBRS channels. In this regard, a CBRS control circuit is provided to present each of the remote units as a uniquely identifiable virtual CBSD to a spectrum access system (SAS) and facilitate communications between the SAS and the remote units. As such, the SAS may be able spoofed to treat the uniquely identifiable virtual CBSD as real CBSDs to uniquely identify each of the remote units for CBRS channel assignment and/or transmission power control. As a result, it may be possible to support CBRS in the DCS in compliance with the Federal Communications Commission (FCC) requirements.

Abstract: Systems and methods for splitting cells in a network of Internet of Things (IOT) may evaluate a network metric such as receives signal strength indicator (RSSI) for end devices to determine a general network activity level. When the network metric falls below a predetermined threshold, the cell splitting controller may cause the cell to split in such a manner as to offload some portion of the end devices on an adjacent gateway and/or change frequencies to reduce the likelihood of collision. By splitting cells in this fashion, the density of end devices served by a single gateway is reduced, fewer collisions occur statistically, and the user experience may be improved.

Abstract: Wireless communications systems supporting carrier aggregation and selective distributed routing of secondary cell component carriers based on transmission power demand or signal quality are disclosed. The wireless communications system includes a signal router circuit communicatively coupled to a signal source. The signal router circuit is configured to distribute a primary cell component carrier, including control information, to each of multiple remote units to be distributed to any mobile device in a respective coverage area of any remote unit to avoid the need to support handovers. In addition, the signal router circuit is configured to selectively distribute one or more secondary cell component carriers to any subset of the remote units based on at least one of transmission power demand or signal quality associated with the remote units.

Abstract: Systems and assemblies for providing both cellular and passive optical local area network (POLAN) data signals along a single, shared fiber optic backbone within an in-building network architecture are provided herein. Systems include a headend unit that combines data signals from a cellular network and optical line terminal (OLT) onto the fiber optic backbone, which is then connected to a series of daisy-chained fiber optic assembly units. An example fiber optic assembly unit includes an asymmetric coupler that splits an input fiber optic signal from the fiber optic backbone into an output fiber optic signal and a throughput fiber optic signal that is fed back onto the continuing fiber optic backbone. The output fiber optic signal is filtered into dense wavelength-division multiplexing (DWDM) channels for providing data signals to a wireless or cellular network and further split into multiple passive optical network (PON) outputs for a local area network (LAN).

Abstract: Embodiments of the disclosure relate to a remote unit supporting radio frequency (RF) spectrum-based coverage area optimization in a wireless distribution system (WDS). A remote unit in a WDS includes a plurality of sector RF paths configured to support sectored coverage areas around the remote unit. Each of the sector RF paths includes an antenna configured to communicate an RF communications signal(s) in an RF spectrum(s). A processing circuit determines a selected downlink sector communications signal(s) to be distributed at a selected power from a selected sector RF path(s) in a selected RF spectrum(s) and provides the selected downlink sector communications signal(s) to the selected sector RF path(s). In this manner, the processing circuit can independently configure a sector RF path(s) to distribute a downlink RF communications signal(s) in an RF spectrum(s) at a desired power(s), thus enabling directional capacity optimization and/or RF interference mitigation around the remote unit.

Abstract: Embodiments of the disclosure relate to optimizing power efficiency of a power amplifier circuit to reduce power consumption in a remote unit in a wireless distribution system (WDS). A power amplifier circuit is provided in the remote unit to amplify a received input signal associated with a signal channel(s) to generate an output signal at an aggregated peak power.

Accordingly, the control circuit configures the power amplifier circuit according to the determined maximum output power. By configuring the maximum output power based on the signal channel(s) in the input signal, it may be possible to optimize the power efficiency of the power amplifier circuit, thus helping to reduce the power consumption of the remote unit.
