Abstract: Presented herein are techniques to shield transmissions from being received and the information contained in them recovered by unwanted devices. Multi-user multiple-input multiple-output (MU-MIMO) techniques are employed, and in particular the spatial dimension aspects of those techniques. Shield nodes are controlled to transmit in a way to obscure the downlink streams transmitted by a wireless access point that are intended for a particular client device to anything outside of the shielded area, and also to obscure uplink streams from one or more client devices to the wireless access point to anything outside of the shielded area but allowing the uplink streams to be well received by the wireless access point.

Abstract: Presented herein are techniques to facilitate infrastructure and policy orchestration in a shared workspace network environment. In one example, a method may include obtaining, by a service broker, a reservation request from a consumer network for a consumer, wherein the reservation request seeks a reservation to reserve, at least in part, at least one workspace device for the consumer for a workspace for a particular day and a particular time period; based on determining that the at least one workspace device is available, providing a response to the consumer network that includes a first indicator for identifying the reservation of the workspace and at least one second indicator identifying the at least one workspace device; and upon receiving a session request from the consumer network that includes the second indicator, establishing a management tunnel to interconnect the consumer network and the at least one workspace device via the service broker.

Abstract: A network of access points (AP) in a high-density environment may be provided. A number of packet transmission retries for one or more of the AP may be determined by setting a number, m, of retries for transmitting a data packet, where m is the upper limit of the number of retries. Data packets are then transmitted m times. Upon transmitting the data packet m times, a success probability SP(u,m) for transmission of the data packet, where u is the number of users, may be calculated. The transmission of the data packet may be repeated m?x times where x is an integer. Upon calculating the success probability for m?x times, a success probability SP(u,m?x) for transmission of the data packet may be calculated. If SP (u,m?x) is larger than SP(u,m) then x may be decreased by one and actions (b)-(f) may be repeated. If SP (u,m?x) is not larger than SP(u,m) then m?x may be set as the maximum number of retries for the data packet.

Abstract: Coordinated Orthogonal Frequency Division Multiple Access (C-OFDMA) in high density networks may be provided. A primary Access Point (AP) and a subordinate AP may be caused to use an omnidirectional antenna pattern during a synchronization period. Next, the primary AP and the subordinate AP may be caused to use an omnidirectional antenna pattern during a time in which the primary AP sends a subordinate Trigger Frame (TF) during a first C-OFDMA period. The primary AP and the subordinate AP may then be caused to use a directional antenna pattern during times in which the primary AP and the subordinate AP Uplink (UL) data during the first C-OFDMA period and Downlink (DL) data during the first C-OFDMA period.

Abstract: Methods are provided in which a network device hosts distinct network access resources that are managed by different entities. The method includes obtaining a request for partitioning one or more network resources of an on-premise network device for connecting one or more endpoints to a first network managed by a first entity. The on-premise network device connects one or more endpoints to a second network managed by a different entity. The method further involves partitioning, based on the request, the one or more network resources and connecting the one or more endpoints to the first network using the one or more network resources. The one or more network resources are managed by the first entity while at least one other network resource of the on-premise network device is managed by the different entity and is associated with connecting the one or more endpoints to the second network.

Abstract: A system and methods by which a reconfigurable intelligent surface device is dynamically configured to control the reflection of transmissions made between an access point and one or more client devices so as to protect the transmissions from being properly received by an unauthorized device. These methods may be used to maintain data confidentiality, particular for remote workers. The positions of the access point and client devices are used to configure the reconfigurable intelligent surface device to reflect the transmissions inward and avoid/minimize leakage outside a physical space.

Abstract: This technology allows for determining the location of client devices via radio scanning for triggered orthogonal frequency-division multiple access (“OFDMA”) uplinks. Access points (“APs”) are configured for OFDMA transmissions. A first AP transmits a trigger frame on particular channel to stations in the wireless network. Neighboring APs scan channels for trigger frames (“TF”). Upon detection of a TF, neighboring APs associate a station identifier with a frequency allocation, or resource unit, in the TF. The neighboring APs receive an OFDMA uplink from the stations, determine a received signal strength indicator (“RSSI”) value for each frequency allocation in the OFDMA uplink, and transmit the RSSI values with the associated station identifier to the first AP. The first AP determines the location of each station by mapping a distance value to the RSSI values.

Abstract: Optimal determination of wireless antenna configurations may be provided. A computing device may direct an antenna array of an Access Point (AP) to generate a wide beamwidth, to locate a cluster of two or more stations. Upon locating the cluster, the AP can narrow the beamwidth, and, with the narrower beamwidth, receive a key performance indicator (KPI) from at least one of the two or more stations in the cluster. The computing device may then generate a statistical model, based on the KPI and an antenna vector of the antenna array. Based on the statistical model, the computing device can determine a second antenna vector to optimize the KPI for one or more of the client stations. The computing device can then modify the antenna state of the AP to generate the determined antenna vector.

Abstract: Optimal determination of wireless network pathway configurations may be provided. A computing device may establish Multi-Access Point (AP) coordination between at least a first AP and a second AP. The first AP can determine an uplink operation is scheduled. When an uplink is scheduled, the first AP can switch its antenna to a narrow beamwidth. The first AP can then receive uplink transmissions from at least a client in the coverage area of the narrow beamwidth. After the uplink transmission, the first AP can then switch the antenna to a larger beamwidth for a next Multi-AP coordination operation.
