  • Patent number: 11470579
    Abstract: Embodiments herein describe using a dual assess point (AP) to establish two access points that both are established by two individual radios (e.g., two 5 GHz radios). Generally, APs experience highly degraded performance when two co-located radios operate within the same band. In one embodiment, AP devices can deploy same band radios using a macro-micro cell approach. Thus, the AP may intelligently hand off client devices between the micro and macro cell in a way that optimizes the system for overall throughput and low packet latency while creating minimal oscillation of clients between cells. The embodiments in this disclosure disclose techniques that direct clients in a manner that optimizes these factors.

  • Patent number: 10701627
    Abstract: In one embodiment, a method implemented on a computing device includes: selecting a wireless access point (AP) to process from among a deployment of wireless access points (APs), defining a neighborhood based on the AP and neighboring APs, where the neighboring APs are within a one-hop radius of the AP, calculating a client distribution optimal received signal strength indicator (RSSI), where the client distribution optimal RSSI (CD optimal) is a minimum receiver start of packet detection threshold (RX-SOP) setting for maintaining existing client device coverage by the AP, calculating a neighbor relations optimal RSSI threshold (NR optimal), where the NR optimal is a function of at least a transmit power control threshold (TPC) for maintaining visibility between the AP and the neighboring APs, calculating an RX-SOP setting for the AP as a function of CD optimal and NR optimal, and applying the RX-SOP setting to the AP.

  • Patent number: 10340975
    Abstract: Receiving filter design that reduces out-of-channel interference for APs is disclosed. An AP includes a first radio and a second radio disposed in a body of the AP. The first radio transmits first signals in a frequency band while the second radio receives second signals in the same frequency band. The AP includes an interference mitigation controller that determines a receiving filter for the second radio to mitigate interference between the first radio and the second radio based on the second signals received by the second radio when the first radio transmits the first signals in the frequency band. The interference mitigation controller applies the receiving filter to signals received by the second radio during a time period that the first radio is transmitting signals in the frequency band while the second radio is receiving signals in the frequency band.

  • Patent number: 9332557
    Abstract: In a wireless local area network, each of multiple access points, in a high density deployment, are configured to suppress co-channel interference. A first access point having a plurality of antennas beamforms a transmission to a wireless client device within a null-space or with the weakest singular eigenmodes of a wireless channel between the first access point and at least one co-channel second access point. Techniques are presented herein for situations in which any given access point has two or more co-channel access points. In addition, an access point may perform receive side suppression with respect to a transmission (made by a co-channel access point to one of its associated wireless client devices) that is received from that co-channel access point.

  • Patent number: 8971443
    Abstract: Techniques are presented to reduce the number of antennas used for a transmission for a given antenna configuration and data rate. At a wireless communication device having a plurality of antennas and capable of sending a transmission via one or more of the plurality of antennas, a determination is made of a data rate and antenna configuration to be used for a transmission. A comparison is made between a total transmit power for a minimum number of antennas for the data rate to be used for the transmission and a total transmit power associated with the antenna configuration for the transmission. When the total transmit power for a minimum number of antennas for the data rate is greater than the total transmit power associated with the antenna configuration for the transmission, the transmission is sent with the minimum number of antennas.
