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).

Integration of a Wi-Fi access point with a cellular radio unit

A device includes a memory and a hardware processor communicatively coupled to the memory. The hardware processor determines that a computing device communicatively coupled to an access point performed an action with respect to the access point and in response to determining that the action causes a deviation from a multi-user uplink policy of the access point, transmits a disciplinary message to the computing device.

Network compliance and admission control

In one embodiment, a first wireless access point (AP) of a first basic service set (BSS) receives, from a second wireless AP of a second BSS, data indicative of an 802.11-based target wake time (TWT) schedule of a client of the second BSS. The first wireless AP identifies, from the receive data, a scheduled communication time of the client of the second BSS in the TWT schedule. The first wireless AP generates an 802.11-based TWT schedule for a client of the first BSS that avoids the scheduled communication time of the client of the second BSS. The first wireless AP sends the generated 802.11-based TWT schedule to the client of the first BSS, wherein the sent TWT schedule causes the client of the first BSS to wake from sleep at a scheduled wake time.

Coordinated target wake time (TWT) service for localized wireless neighborhoods

Bypassing radar in wide Dynamic Frequency Selection (DFS) channels utilizing puncturing may be provided. A first client device may be classified as eligible for puncturing and a second client device may be classified as not eligible for puncturing. Next, it may be determined that a subchannel in a bandwidth range should not be used. Then, in response to determining that the subchannel in the bandwidth range should not be used, the first client device may be steered to a first subset of the bandwidth range and the second client device may be steered to a second subset of the bandwidth range. The second subset of the bandwidth range may be smaller than the first subset of the bandwidth range.

A management entity obtains from a first wireless access point a Basic Service Set (BSS) color collision event detected by the first wireless access point. The first wireless access point uses a first BSS color. A color collision event occurs when the first wireless access point receives from a device in a BSS of a different physical wireless access point a frame or PHY Protocol Data Unit (PPDU) that includes the first BSS color. The management entity obtains from the first wireless access point an indication whether the color collision event has been detected for longer than a predetermined duration. When the color collision event has been detected for longer than the predetermined duration, the management computes a probability of the color collision event. The management entity determines whether the color collision event is malicious or benign, and determines whether to maintain the first BSS color.

Detecting and preventing denial of service attacks due to fraudulent BSS color collision events

In one embodiment, a method includes receiving a plurality of radio frequency chains at a wireless device in a block based modulation environment, recording subcarrier phases and differences between the subcarrier phases, and using the subcarrier phase differences to construct a feature vector for use in angle of arrival calculated positioning of a mobile device.

Angle of arrival location sensing with antenna array

A method for scheduling a random access trigger frame (RA TF) in a wireless LAN includes determining whether a scheduled access (SA) TF is scheduled during a beacon interval (BI) beginning with a next beacon; determining whether one of, a first weighted average of a sum of (i) a number of clients whose respective buffer status reports (BSRs) have been successfully received (N) and (ii) a number of clients whose respective BSRs collided with one another (N) is greater than a first threshold, or a second weighted average of an active number of UL OFDMA enabled HE users sending SU uplink traffic (N) is greater than the first threshold; when either weighted average is greater than the first threshold, allocating a predetermined number of RA RUs along with at least one SA RU in a buffer status report poll (BSRP) TF and scheduling the BSRP TF for transmission.

Random access trigger frame based uplink OFDMA scheduling mechanism

In an example embodiment disclosed herein there is described a multi-radio device which comprises a first radio that first radio comprises a transmitter, and a second radio that second radio comprises a receiver that monitors a channel to obtain data representative of a predefined channel parameter. The second radio is operable to receive a signal from the first radio that indicates when the transmitter of the first radio is transmitting. The receiver of the second radio selectively excludes data representative of a predefined channel parameter based on whether the transmitter of the first radio is transmitting.

Presented herein is a tone plan that can accommodate multiple bandwidth options. This tone plan may be designed around a fundamental tile, such as 20 MHz tile, that is replicated to 40 and 80 MHz (and 160 MHz and beyond). For wider bandwidths, the otherwise-unused guard tones between the 20 MHz tiles are filled by a new resource unit and DC tones. There are DC tones placed to support any client, for all defined and plausible future values of its current operating bandwidth and center frequency (i.e. any 20 MHz, any 40 MHz, any 80 MHz, 160 MHz and 80+80 MHz, 320, 160+80 etc.), as well as plausible future preamble puncturing cases.

Multi-band width tone plan for OFDMA in a wireless network

Presented herein are methodologies for handling multicast traffic that is transmitted to mobile devices in a given basic service set (BSS). The methodology includes detecting membership of clients in an Internet Protocol (IP) multicast group in a basic service set of a wireless network; determining whether the IP multicast group and its associated multicast traffic meet predetermined criteria; when the IP multicast group and its associated multicast traffic meet the predetermined criteria, negotiating with each client in the IP multicast group to have a target wake time (TWT) that includes, at least, a coincident overlap window of sufficient duration to transmit the multicast traffic associated with the IP multicast group; and transmitting the multicast traffic associated with the IP multicast group during the coincident overlap window, wherein the coincident overlap window is different from a delivery traffic indication message (DTIM) service period.

Use of target wake time to reduce delivery traffic indication message multicast
