  • Patent number: 12451983
    Abstract: Architectures and techniques are presented that can provide point-to-point analysis to generate an improved signal strength prediction (SSP) based on, e.g., earth surface image data processing and analysis to draw conclusions of line of sight (LOS) along the propagation path between a BTS or another AP transmitter and CPE receiver. For example, USGS image data and/or elevation data of locations are identified to correspond to signal propagation between the transmitter and receiver can be analyzed for LOS signal quality at a fixed location, in addition to the statistical model prediction of the RF signal quality. As a result, foliage or terrain that obstructs the LOS can be identified and utilized to improve SSP by eliminating the additional pathloss due to LOS obstructions. Such can provide a significant improvement to SSP results that are conventionally predicted by statistical models rather than a point-to-point analysis.

  • Publication number: 20220386136
    Abstract: Facilitating analysis and resource planning for advanced heterogeneous networks (e.g., 5G, 6G, and beyond) is provided herein. A system is provided that includes a processor and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. The operations can include determining that a resource is to be added to existing resources at a grid level of a heterogeneous network. Further, the operations can include selecting candidate locations for placement of the resource based on a coverage-driven objective and a capacity-driven objective defined for the heterogeneous network. The coverage-driven objective can be associated with a demand for services within the grid level of the heterogeneous network. The capacity-driven objective can be associated with demand growth within the grid level of the heterogeneous network. The resource can be a fifth generation millimeter wave node or a cloud radio access network node.

  • Patent number: 10798537
    Abstract: A speed tier based pricing scheme is utilized to increase average revenue per user (ARPU) for fixed wireless applications. To offer a speed tier based pricing scheme, a radio environment at a location of Customer Premise Equipment (CPE) and/or data associated with cell sites serving the location can be analyzed to estimate a maximum data rate that can be delivered to the user CPE with a high confidence. Based on the estimated data rate, one or more speed tiers that can be offered to the customer for subscription. Further, based on an analysis of observed network usage and/or traffic demand per customer location with reference to the speed-tier classes subscribed to by existing customers, the network can efficiently plan for on-boarding new customers and/or network expansion.
