Abstract: A hollow-core optical fiber may include a hollow core extending along a central longitudinal axis of the fiber; a substrate; a plurality of first cladding elements spaced apart from each other and positioned between the hollow core and the substrate, each of the first cladding elements extending in a direction parallel to the central longitudinal axis of the fiber, each of the first cladding elements including a first capillary; and a plurality of second cladding elements spaced apart from each other and positioned between the hollow core and the substrate, each of the second cladding elements extending in a direction parallel to the central longitudinal axis of the fiber, each of the second cladding elements including a second capillary. Each of the first cladding elements directly contacts the inner surface of the substrate, and none of the second cladding elements directly contacts the inner surface of the substrate.

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: Embodiments of the disclosure relate to a massive multiple-input multiple-output (M-MIMO) wireless distribution system (WDS) and related methods for optimizing the M-MIMO WDS. In one aspect, the M-MIMO WDS includes a plurality of remote units each deployed at a location and includes one or more antennas to serve a remote coverage area. At least one remote unit can have a different number of the antennas from at least one other remote unit in the M-MIMO WDS. In another aspect, a selected system configuration including the location and number of the antennas associated with each of the remote units can be determined using an iterative algorithm that maximizes a selected system performance indicator of the M-MIMO WDS. As such, it may be possible to optimize the selected system performance indicator at reduced complexity and costs, thus helping to enhance user experiences in the M-MIMO WDS.
