  • Publication number: 20250023777
    Abstract: Devices, systems, methods, and processes for managing network devices through generated predictions and associated confidence levels are described herein. Networks within a floorplan can be operated at full capacity all day in an inefficient way when not adjusted due to traffic patterns and seasonality changes. Data related to the topology of the network, along with historical data can be utilized to generate predictions of various network needs. For example, the overall network throughput capacity needs may be predicted for a series of points in the future. An associated confidence level can be generated as well including one or more confidence intervals. These can be utilized to select a future need for the network and generate a corresponding sustainable network configuration for the network devices and/or their transceivers that can provide sufficient network needs while minimizing the overall power used. This can be automated over time once trust has been established.

  • Patent number: 12177943
    Abstract: In one embodiment, a gateway to a Layer-3 network forms a first Layer-2 tunnel between the gateway and a first wireless access point (AP) that communicates wirelessly with a first mobile node of a mobile system (MS) via a first wireless connection. The gateway generates a mapping that associates an onboard device of the MS with the first AP and an identifier for the MS, based on traffic conveyed via the first Layer-2 tunnel and associated with the onboard device, the traffic comprising a header that indicates the identifier for the MS. The gateway receives, from a second AP, an indication that the MS is roaming from the first wireless connection to a second wireless connection, the indication including the identifier for the MS. The gateway updates the mapping to associate the onboard device of the MS with a second AP, based on the indication that the MS is roaming.

  • Publication number: 20240345200
    Abstract: A method includes determining a 2D DEM for a physical environment, determining a viewshed for an access point in the physical environment using the DEM, and identifying, at the end terminal, at least one obstacle that is visible from the access point. For each point in space within the physical environment that is on a same side of the at least one obstacle as the access point: a respective first RSSI is determined, the respective first RSSI being associated with a direct LOS ray from the access point to a point in the space. A respective second RSSI for each of the at least one obstacle is determined to yield at least one second RSSI. A respective RF power based on the respective first RSSI and the at least one second RSSI is also determined, the respective RF power being used for generating a 3D heatmap for the physical environment.

  • Patent number: 12041461
    Abstract: The present technology is directed to visualizing a Wi-Fi signal propagation in 3-D at various heights and locations. The present technology can calculate a radio frequency (RF) propagation pattern for a Wi-Fi access point (AP) based on a RF propagation model for the Wi-Fi AP and overlay the RF propagation pattern for the Wi-Fi AP over a visualization of the building plan to present a 3-D visualization of the RF propagation pattern of the 3-D space. In particular, the present technology can project a plurality of ray-paths in various directions in a 3-D space originated from the Wi-Fi AP and determine whether the ray-paths interface with objects defined in the building plan. The present technology can segment the respective ray-path into contiguous segments of substantially uniform mediums for each ray-path that interface with the objects and determine a RF signal strength at points along the contiguous segments of the ray-paths.
