Abstract: A radio access network (RAN) of a neutral host network (NHN) provides communications in a plurality of small cells, and is a shared resource with shared access by a plurality of mobile network operators (MNOs) via a multi-operator core network (MOCN). A base station maintains a neighbor list of small cell frequencies of neighboring small cells of a small cell, and broadcasts, to a user equipment (UE), a system information message which includes the neighbor list. The base station additionally maintains a plurality of operator-specific neighbor lists of one or more macro-cell frequencies of one or more neighboring macro-cells, where each such list is associated with a respective one of a plurality of macro-cellular networks of the MNOs. The base station transmits, to the UE, a message including a selected one of the operator-specific neighbor lists associated with an identified one of the mobile network operators of the UE.

Abstract: Systems, methods, and computer-readable media for an integrated Wi-Fi Access Point and cellular network Radio Unit (RU) include a communication system interfacing with a wired network for communicating Wi-Fi traffic and cellular network traffic, the communication system integrating a Wi-Fi Access Point (AP) with a cellular network Radio Unit (RU). The Wi-Fi traffic and cellular network traffic can be processed in the communication system. The communication system can interface with at least one programmable Radio Frequency (RF) front end configured for wireless communication over one or more frequency bands for Wi-Fi traffic and one or more frequency bands for cellular network traffic (e.g., 5G, LTE, Wi-Fi).

Abstract: An access point for a private network onboards a wireless device obtaining a connection request from the wireless device and detecting a standardized identifier that indicates the wireless device is unprovisioned for access to the private network. The access point disables an authentication protocol for granting access to the wireless device on the private network and limits access of the private network by the wireless device to accessing a provisioning server. The access point provides a connection response to the wireless device that indicates limited access to the private network.

Abstract: The present disclosure is directed to mapping indoor user movement using a combination of Wi-Fi and 60 GHz sensing. The methods include detecting, via a Wi-Fi access point, a wireless device associated with a first user, wherein the Wi-Fi access point is configured to determine location information and a device signature associated with the wireless device; transmitting the location information of the wireless device to a 11ay sensor; detecting the first user, via the 11ay sensor, based on the location information of the wireless device; creating a user signature associated with the first user, wherein the user signature is based on one or more physical characteristics of the first user detected by the 11ay sensor; and using the device signature associated with the wireless device and the user signature associated with the first user to subsequently identify the first user.

Abstract: In one embodiment, a device in a network determines behavioral profiles of a plurality of nodes in the network. The behavioral profile for a particular node indicates whether the node is an occasional transmitter or a periodic transmitter. The device identifies similarly behaving nodes based on their behavioral profiles. The device assigns groups of the nodes to uplink transmission windows based on their behavioral profiles. The similarly behaving nodes that are periodic transmitters are assigned to the same uplink transmission windows and similarly behaving nodes that are occasional transmitters are assigned to different uplink transmission windows. The device controls the plurality of nodes to use their assigned uplink transmission windows via target wake time values sent to the plurality of nodes.

Abstract: In one embodiment, a process determines how often client devices roam from a given access point (AP) to each particular neighbor AP of a plurality of neighbor APs of the given AP, and correspondingly determines a roaming distance from the given AP to each particular neighbor AP, the roaming distance being shorter for neighbor APs roamed to more often, and longer for neighbor APs roamed to less often, within a given interval. Successful but temporary roams to the plurality of neighbor APs may also be detected and removed from consideration in the roaming distance to that particular neighbor AP. The process then generates a proximity list of one or more of the neighboring APs having the shortest roaming distances, and feeds the proximity list to the given AP to cause the given AP to provide the proximity list to client devices for optimized client roaming.
