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.

Abstract: The present technology is directed to providing a 3-D visualization of a Wi-Fi signal propagation pattern based on telemetry data. The present technology can receive telemetry data for a Wi-Fi access point located at a location of a building plan in a Wi-Fi visualization system, store the telemetry data with a timestamp, determine a change in a Wi-Fi coverage for the Wi-Fi access point based on the telemetry data, and present a visualization illustrating the change in the Wi-Fi coverage for the Wi-Fi access point. The present technology can further present an animation of the change in the Wi-Fi coverage for the Wi-Fi access point based on the stored telemetry data.

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.

Abstract: A system and a method to dynamically reprovision network devices may include a first network device configured to reprovision a second network device in accordance with a specific location of the second network device in a predefined area. The first network device may be configured to sense the second device at the specific location in the predefined area, identify reprovisioning parameters associated with the specific location, and provide the reprovisioning parameters to the second network device. In turn, the second network device may be configured to perform one or more roles associated with the specific location in the predefined area based at least in part upon information in the reprovisioning parameters.

Abstract: The present technology is directed to visualizing a Wi-Fi access point (AP) signal propagation pattern through multiple floors. The present technology can execute a Wi-Fi signal propagation model corresponding to a first AP on a first floor of a building plan and a second AP on a second floor of the building plan. The Wi-Fi signal propagation model calculates a Wi-Fi signal propagation pattern for a plurality of APs including the first AP and the second AP. The present technology can further present a visualization of the Wi-Fi signal propagation pattern for the plurality of APs, wherein the Wi-Fi signal propagation pattern for the first AP on the first floor of the building plan projects onto the second floor of the building plan.
