    Abstract: Successive interference mitigation in Automated Frequency Coordination (AFC) may be provided. A plurality of messages may be received from a respective plurality of Access Points (APs). Each of the plurality of messages may indicate a respective channel used by a respective one of the plurality of APs associated with the message. An indication may be received that an Interference to Noise (I/N) ratio is above a predetermined threshold in a Fixed Service (FS) channel associated with an FS. At least one of the plurality of APs may be identified as a cause of the I/N ratio being above the predetermined threshold in the FS channel based on a channel used by the identified at least one of the plurality of APs and the FS channel. An action may be taken against the identified at least one of the plurality of APs to lower the I/N ratio.

    Abstract: Real-time radio self-calibration may be provided. The self-calibration may begin by sampling a Transmission (TX) signal. An achievable Error Vector Magnitude (EVM) for one or more frames may be determined based on the TX signal. Link budgets for clients may be determined using a TX power and a supported Modulation and Coding Scheme (MCS). A per packet TX power is adjusted based on the achievable EVM and a TX retry rate. The PA linearity of the radio may also be adjusted based on the achievable EVM and the link budget. The client may be regrouped into a new MCS based on the link budget.

    Abstract: Techniques for coordinating traffic statistics and managing accounting sessions for multi-link operation are provided. A first communications link with a second network device is established by a first network device. A first accounting request to a third network device is transmitted by the first network device, where the first accounting request indicates that the second network device comprises a station multi-link device (STA MLD). A first accounting response is received by the first network device, indicating whether the third network device supports statistic aggregation. Traffic statistics for the first communication link is collected by the first network device, and reported to the third network device in accordance with the first accounting response.

    Abstract: The present disclosure describes a network and a method of operating the network. The method includes determining that a portion of a first channel of a first access point overlaps a portion of a second channel of a second access point and in response to determining that the portion of the first channel overlaps the portion of the second channel, adjusting the first access point so that the first access point refrains from transmitting using frequencies in the portion of the first channel that the second access point uses to transmit pilot tones in the portion of the second channel.

    Abstract: In one embodiment, a system for allocating clients between radios of an access point is disclosed. The system includes a first antenna coupled to a first radio, a second antenna coupled to a second radio, and a monitoring radio coupled to the first antenna and second antenna. The system includes computer-readable instructions that cause the system to receive at the monitoring radio, a first client attribute from each of a plurality of first client devices, and a second client attribute from each of a plurality of second client devices, and provide each aforementioned attribute to an optimization function. The system determines, with the optimization function, that one of the first radio and second radio will optimize performance for at least one device of the plurality of first client devices and second client devices and steer the at least one device accordingly.
