    Abstract: The present disclosure is directed to determining a first radio as a downlink for transmitting data frames from a first wireless endpoint device to second wireless endpoint devices, determining a second radio as an uplink for transmitting data frames from the second wireless endpoint devices to the first wireless endpoint device, enabling transmissions of data frames from the second wireless endpoint devices to the first wireless endpoint device on the uplink, detecting a first data frame with a latency requirement to be transmitted from the first wireless endpoint device to a targeted second wireless endpoint device, replacing any data frame not associated with a latency requirement in an aggregated MAC protocol data unit with the first data frame, and transmitting the first data frame to the targeted second wireless endpoint device on the downlink.

    Abstract: Method, system, and/or computer readable medium for roaming on a Wi-Fi network having a plurality of access points including: determining that a new AP actor provides a station (STA) actor enhanced characteristics as compared to an existing AP actor, wherein the enhanced characteristics include one or more of a stronger connection, lower congestion, and/or increased bandwidth; transferring required state from the existing AP actor to the new AP actor; and transferring at least some of data wherein the at least some data includes one or more of medium access control service data units (MSDUs), aggregated-MSDUs (A-MSDUs), medium access control protocol data units (MPDUs), and/or aggregated-MPDUs from the existing AP actors to the new AP actor.

    Abstract: Method, system, and/or computer readable medium for establishing an upper upper medium access controller (upper UMAC); establishing a connection, between the upper UMAC and a station (STA) actor, over a plurality of access point actors (AP actors), wherein each of the AP actors includes a lower upper medium access controller (UMAC), a lower medium access controller (LMAC), and a physical layer (PHY); transmitting one or more proto-medium access controller protocol data units (proto-MPDUs) from the upper UMAC to the plurality of AP actors; attaching PHY and MAC metadata to the one or more proto-MPDUs; and forming, at each of the plurality of AP actors, a PHY protocol data unit (PPDU), wherein each PPDU is formed from a corresponding one of the one or more proto-MPDUs.

    Abstract: An access point determines the highest signal strength at which it can detect transmissions from other access points or overlapping-basic-service-set (OBSS) client devices associated with the other access points. The access point sets an OBSS packet-detect threshold to the lesser of a minimum cell-size threshold or the highest signal strength and sets a receiver start-of-packet (RxSOP) threshold to the OBSS packet-detect threshold minus an offset. The access point avoids decoding incoming packets when respective signal strengths of the incoming packets do not satisfy the RxSOP threshold. The access point also avoids initiating transmission when incoming packets from the other access points or from the OBSS client devices have signal strengths that satisfy the OBSS packet-detect threshold.

    Abstract: In one embodiment, an apparatus includes a plurality of antennas, a receiver in communication with said plurality of antennas for receiving one or more packets in a block based modulation environment, a switch interposed between a portion of the antennas and the receiver for switching between the antennas, and a processor for calculating angle of arrival for use in identifying a location of a mobile device transmitting the one or more packets.

    Abstract: An access point in a wireless network communicates wirelessly with one or more client devices over a channel that includes a plurality of subchannels. Each subchannel corresponds to a distinct frequency chunk with a respective plurality of subcarriers. Radar is detected on a first subchannel. In response, a selection is made between (i) redefining the channel and (ii) puncturing the first subchannel while continuing to use all other subchannels. Puncturing the first subchannel includes muting subcarriers on the first subchannel. Redefining the channel includes removing multiple subchannels from the channel. The selection is based at least in part on one or more factors that provide indications as to whether puncturing would be efficient and/or effective. The access point continues to communicate wirelessly with the one or more client devices in accordance with the selection.
