  • Patent number: 11523316
    Abstract: Distribution of traffic to cells in a communication network can be controlled. A distribution management component (DMC) can determine overall device traffic throughput for cells of a sector that satisfy a defined traffic throughput criterion relating to a harmonic mean of the device traffic throughput for the cells to desirably enhance or maximize the harmonic mean of the overall device traffic throughput. Based on the overall device traffic throughput for the cells, the DMC can determine whether to adjust a characteristic associated with a cell of the cells to facilitate adjusting distribution of device traffic among the cells of the sector to achieve desirable load balancing of traffic by the sector and in the network. Load balancing can be achieved by controlling respective parameters with regard to communication devices that are in idle mode or connected mode to facilitate directing communication devices and associated traffic to desired cells.

  • Patent number: 10541471
    Abstract: Aspects of the subject disclosure may include, for example, an antenna assembly that includes a dielectric antenna having an integrated dielectric feedline and a dielectric antenna element. The integrated dielectric feedline communicates inbound guided waves and outbound guided waves that are bound to the integrated dielectric feedline. The dielectric antenna element transmits outbound free space wireless signals in response to the outbound guided waves and generates the inbound guided waves from received inbound free space wireless signals. An actuated gimbal mount controls an orientation of the dielectric antenna element based on control signals. Other embodiments are disclosed.

  • Patent number: 10523388
    Abstract: Aspects of the subject disclosure may include, for example, a transceiver that converts first modulated channel signals in a first spectral segment to the first modulated channel signals in a second spectral segment based on signal processing of the first modulated channel signals and without modifying the signaling protocol of the first modulated channel signals. The transceiver transmits, via a fiber optic cable, a transmission signal including a first reference signal with the first modulated channel signals in the second spectral segment to a network element of a plurality of network elements of the distributed antenna system for wireless distribution of the first modulated channel signals to mobile communication devices in the first spectral segment. The first reference signal enables the distributed antenna system to reduce a phase error during processing of the first modulated channel signals from the second spectral segment to the first spectral segment.
