Abstract: Methods and systems for multifactor authentication and authorization are described. A method includes receiving captured image data of a person with a badge needing access to a secure area, detecting at least two faces from the captured image data, identifying a first name based on matching a face associated with a live human face with a control face in a database, identifying a second name based on matching on another face associated with the badge with a control face in a database, performing character recognition on text associated with the another face, comparing the second name with the character recognized text, comparing the second name with the first name when the second name matches the character recognized text, checking access rights, checking for at least another person in a proximity of the secure area, and granting access when the person is sole person accessing the secure area.

Abstract: A network server selects a gateway, from among a plurality of alternative candidate gateways, to use for downlink wireless communication to an end node (EN) based on additional factors in addition to RSSI. Exemplary additional factors include: SNR, gateway loading, message loading, backhaul network loading, device type, application type, application priority, operator preferences, device/application black-lists, white-lists, and red-lists, number of devices, number of transmitting devices in a given time interval, operator rules and priorities. In some embodiments, the network server calculates a composite weighted metric (CWM) for each of the alternative candidate gateways which may be used for downlink, subject to operator policy rules, and selects to use a gateway based on the results, e.g. selects the gateway with the highest CWM.

Abstract: Methods and systems for real-time detection and reporting of trains is described. A system includes two train detection units (TDUs) for each railroad track intersecting a municipality boundary. Each TDU including a proximity sensor to sense a presence of an object on the railroad track, a camera to capture an image of a detected object when the object is within a detection zone, a radar to measure speed when the detected object is classified as a train, and a processor to classify the detected object, generate a timestamp corresponding to when the train entered and exited the detection zone, and determine a train length from the speed and time delta between entrance timestamp and exit timestamp. A train detection controller to receive at least the train length and a TDU identification from one of the two TDUs, and determine estimated time of arrivals for the train at different municipality locations.

Abstract: Various embodiments comprise systems, methods, architectures, mechanisms and apparatus for optimizing the delivery of multicast messages to a set of targeted (receiver) devices via a low power wide area (LPWA) network such as by minimizing a number of gateway devices in a set of gateway devices needed to reach the target devices, by optimizing the use of radio communication resources to minimize costs associated with using metered backhaul network services (e.g., costs associated with using cellular network backhaul services), by maximizing the resiliency, speed, or synchronization of the set of gateway devices, by favoring operator-owned resources, or by achieving other goals consistent with operator policies, preferences and other considerations.

Abstract: Methods and apparatus for managing radio device transmitters, beams, and receivers within a power-limited system. In one embodiment, the methods and apparatus utilize so-called “quasi-licensed” CBRS (Citizens Broadband Radio Service) wireless spectrum in conjunction with a distributed controller architecture that dynamically allocates frequency, base station, and transmit/receive beam resources for delivery of services to a number of installed fixed wireless apparatus (FWA) at user or subscriber premises. The FWA include radio path controller logic that obtains signal data via its antennae and radio head, and transmits the data to a network centralized controller that determines the resource allocation and timing (e.g., via a slotted TDD medium) for service delivery to each FWA. As such, the base stations do not determine the allocations as in the prior art, and multiple power-limited base stations can transmit signals to a single FWA to achieve greater coverage area and/or receive aggregated power.

Abstract: A user device includes and maintains a geolocation list (GLL) including sets of information corresponding to Citizens Broadband radio Services Devices (CBSDs). The GLL stored in the user device contains entries corresponding to the areas most recently visited by the UE, each entry including location information of a CBSD. User devices typically frequent a limited set of the same areas repetitively. Thus this maintained relatively small list provides the UE with a highly relevant set of information which can be quickly accessed without additional wireless signaling and the additional power loss associated with a typical search. When the UE desires to find and connect to a CBSD, the UE first searches its GLL for a CBSD providing coverage in its currently located area. However, if GLL search does not identify a CBSD, then the UE sends a request to a geolocation server for active CBSDs.

Abstract: Apparatus and methods for registering and authenticating a client device with a wireless-enabled network. In one embodiment, the apparatus and methods provide an alternate wireless connectivity link to register an installed high-power fixed wireless apparatus (FWA) or Customer Premises Equipment (CPE) with a managed wireless network infrastructure, such as one utilizing “quasi-licensed” CBRS (Citizens Broadband Radio Service) wireless spectrum or another shared access approach. In one variant, the alternate wireless link comprises a mobile cellular channel established via an application program executing on a mobile device. In another variant, an Internet of Thing Network (IoT) is used for the alternate link. In one implementation, spectrum grants are communicated back the FWA/CPE via the alternate link to enable subsequent CBRS-band high-power operation.

Abstract: An end point (EP) device may communicate with multiple gateways via wireless signals, e.g. wireless broadcast signals. An EP device is controlled, under the direction of a control server, e.g., an application server, to communicate via a single gateway. The control server associates the EP device with a single target gateway and/or uses EP transmission power control training iterations to reduce the EP transmission power level until the EP device is only able to successfully communicate its wireless signals to a single gateway.
