SYSTEMS AND METHODS FOR MACHINE LEARNING BASED DYNAMIC SELECTION OF DUAL CONNECTIVITY OR CARRIER AGGREGATION
Systems and methods for machine learning based dynamic selection of dual connectivity or carrier aggregation are provided. 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 user equipment. The system further includes a machine learning computing system configured to receive time data and traffic data, and determine a predicted mode of operation for a UE based on the time data and the traffic data. Component(s) of the system are configured to receive a request from the UE, and dynamically select a dual connectivity mode or a carrier aggregation mode for operation of the UE based on the predicted mode of operation for the UE.
The present disclosure relates to a telecommunication optical fiber distribution architecture including fiber indexing branches and enhanced signal path routing flexibility. In certain examples, a flexibility terminal can be used to define a branching location for originating multiple branches each defined by terminals that are daisy chained together. The flexibility terminal can include demateable connection locations for allowing feeder signals to be selectively connected to signal lines of the branches. The signal lines of the branches can include indexed signal lines that are passed through indexing terminals in an indexed configuration and are indexed toward drop lines of the indexing terminals, non-indexed signal lines that are passed through indexing terminals in a non-indexed configuration, and point-to-point terminals for accessing the non-indexed signal lines.
A fiber optic splice organizer includes a mounting bracket, and at least one tray of a first type attached to the mounting bracket. The first type of tray has a first length and an interior volume for storing fiber optic splices. At least one tray of a second type is attached to the mounting bracket. The second type of tray has a second length and an interior volume for storing a different quantity of fiber optic splices than the first type of tray. A modular extension is attachable to the first or second types of trays to increase their respective lengths.
Twin-beam base station antennas are provided. A twin-beam base station antenna includes a plurality of vertical columns of radiating elements that are configured to transmit radio frequency signals in a frequency band. The radiating elements have bent metal radiator arms including tip portions that face respective center axes of the radiating elements.

The present disclosure relates to a connector assembly and a base station antenna comprising such connector assembly. The connector assembly comprises a connector (1), where the connector has a port (11). The connector assembly further comprises a guide ring (2), where the guide ring is installed in front of the port of the connector and is radially and elastically supported. The guide ring has an inner surface (21) that tapers towards the port of the connector on part of the axial length, and is used to guide the port of the matching connector in the port of the connector. The connector assembly allows increased deviation when matching connectors are mated.

CROSS-DIPOLE RADIATING ELEMENTS HAVING FREQUENCY SELECTIVE SURFACES AND BASE STATION ANTENNAS HAVING SUCH RADIATING ELEMENTS
Antennas include a first radiating element that is configured to operate in a first operating frequency band, and a second radiating element that is configured to operate in a second operating frequency band that encompasses higher frequencies than the first operating frequency band. The first radiating element includes a first dipole radiator having first and second dipole arms and a second dipole radiator having third and fourth dipole arms. The first dipole arm includes a first metal region that substantially surrounds a first non-metal interior region, and the first non-metal interior region is configured so that currents induced on a first portion of the first metal region by RF energy emitted by the second radiating element substantially cancel currents induced on a second portion of the first metal region by the RF energy emitted by the second radiating element.
