A base station antenna sector includes: a first reflector comprising a first flat panel and a plurality of first radiating elements mounted thereon; a second reflector comprising a second flat panel and plurality of second radiating elements mounted thereon; a radome surrounding the first and second reflectors; wherein the second reflector is pivotally movable relative to the first reflector.

Embodiments described herein relate to a host unit for a distributed antenna system. The host unit includes a first radio access network (RAN) interface module to communicate with a RAN node. The host unit also includes a distribution module configured to distribute transport signals between one or more downstream RJ45 connectors and the first RAN interface module. One or more non-permanent connectors are included to couple the distribution module to a second RAN interface module and one or more upstream RJ45 jacks. The one or more upstream RJ45 jacks are configured to pass Ethernet signals therethrough. The distribution module is configured to couple a downlink portion of the first transport signals and either a downlink portion of the second transport signals or a downlink Ethernet signal from one of the upstream RJ45 jacks to a first twisted pair cable connected to one of one or more downstream RJ45 jacks.

The present application relates to a base station antenna, where the base station antenna includes a radome and a reflector assembly housed within the radome having an open upper end portion that is closed by an upper end cap, the base station antenna further has a ventilation system that includes a flow channel disposed in the upper end cap or disposed between the upper end cap and the upper end portion of the radome, and the flow channel is configured for venting from the inside of the radome through the flow channel to an external environment. The base station antenna can achieve improved heat dissipation performance.

This invention relates to a DAS comprising a digital donor interface circuit, an RF donor interface circuit, a first DAS propagation path, a second DAS propagation path, and a radio unit and configured to obtain a first propagation time delay for the first DAS propagation path and a second propagation time delay for the second DAS propagation path, obtain at least one of a time delay of the RF donor interface circuit and the digital donor interface circuit, determine a first downlink time delay value, and transmit the first downlink time delay value to a delay adjustment circuit in a downlink path of the DAS.

The present disclosure describes a sector frame antenna mount assembly. The assembly includes a plurality of horizontal members, each horizontal member having a length, a plurality of vertical members mounted on the horizontal members, each vertical member configured to have at least one antenna mounted thereon, and at least one offset adapter configured to mount a selected one of plurality of vertical members to a selected on of the plurality of horizontal members. The selected vertical member is repositioned via the at least one offset adapter from a first mounting location to a second mounting location along the length of the selected horizontal member or past an end of the selected horizontal member, thereby addressing issues with respect to passive intermodulation or other spacing issues within the assembly. Offset adapters and other related antenna mount assemblies are also described herein.

A cellular base station antenna assembly includes: a telecommunications antenna with plurality of first communication ports mounted on a rear surface thereof; a remote radio unit mounted to the antenna having a plurality of second communication ports on a lower surface thereof; and an adapter configured to connect the remote radio unit to the antenna, the adapter including a housing, a first clustered connector that includes a plurality of individual first connectors, the first clustered connector being mounted on a lower portion of the housing, the adapter further including a plurality of second connectors mounted on an upper surface of the housing, each of the first connectors being connected with a respective second connector. Each of the second connectors is mated with a respective second communication port, and each of the first connectors is mated with a respective first communication port. The assembly further includes a disengagement mechanism connected to the assembly and configured to raise the remote radio unit relative to the adapter to disengage the second connectors from the second communication ports.

Techniques are provided for diminishing latency in a DAS fronthaul network configured to convey time-domain transport data, e.g., time-domain digital transport data or time-domain digital data. Other techniques are provided for obtaining higher DAS fronthaul efficiency.

An antenna-radio module for a cellular base station includes: an antenna having a cylindrical outer surface and a lower surface, wherein a plurality of antenna communications ports are present in the lower surface; and a plurality of radio sectors, each of the radio sectors having an outer surface and an upper surface, wherein at least one radio communications port is present on the upper surface. The plurality of radio sectors are arranged to form an annulus. Each of the radio communications ports is mated in a blind-mate configuration to a respective one of the antenna communications ports. The module further includes an elongate member inserted through the annulus, the radio sectors and the antenna being mounted to the elongate member.

Techniques are provided for diminishing power loss in electrical conductors used to provide electrical power to a radio configured to use time domain duplexing (TDD). Because the TDD radio typically transmits data during a downlink subframe, the TDD radio generally consumes more power, and thus draws more current through the electrical conductors, then during an uplink subframe when the TDD radio is configured to receive. Thus, during the downlink subframe, a DC voltage, output by a DC-DC voltage converter to the electrical conductors, is increased to lessen current drawn by the radio through the electrical conductors. As a result, power loss in the electrical conductors is reduced.

Systems and methods for ML based ACB are provided herein. In an example, a system includes BBU(s), RU(s) communicatively coupled to the BBU(s), and antenna(s) communicatively coupled to the RU(s). Each respective RU of the RU(s) is communicatively coupled to a respective subset of the antenna(s). The BBU(s), the RU(s), and the antenna(s) are configured to implement a base station for wirelessly communicating with UEs in a cell. The system includes a machine learning computing system configured to: receive time data, traffic data, and location data; and determine predicted barring parameter(s) for the base station based on the time data, the traffic data, and the location data. The system is configured to: adjust barring factor(s) and/or barring time(s) in an information message based on the predicted barring parameter(s) for the base station; and send the information message with the adjusted barring factor(s) and/or barring time(s) to UEs in the cell.
