    摘要： A wireless transceiver having radios which radios that support wireless communications with associated stations on a corresponding wireless local area network (WLAN). The wireless transceiver also includes: a utilization monitoring circuit, an association targeting circuit, and a power backoff circuit. The utilization monitoring circuit monitors communications between each of the radios and its associated stations. The association targeting circuit identifies, from the monitored communications of the utilization monitoring circuit, an underutilized one of the radios as a target radio for re-associating stations currently associated with at least one other radio and initiates the re-association with the target radio of the stations currently associated with the at least one other radio. The power backoff circuit reduces power to the at least one other radio.

    摘要： Methods and systems may include processes by which the reliability and robustness of a wireless network may be improved. In some implementations, a method may include selecting at least two resource units to be used for communications to a single client device; and transmitting data in duplicate via each of the at least two resource units to the client device such that the client device is able to combine the data from each of the at least two resource units into a single instance of the data. In some implementations, a method may include obtaining notification of one or more ranges of frequencies corresponding to a set of resource units to be avoided in a spectrum of available frequencies, and allocating resource units to a set of client devices that covers the available frequencies while excluding the set of resource units to be avoided.

    摘要： A method to operate a wireless access point (WAP) that includes identifying multiple stations from uplink statistics of a plurality of uplinks and determining an optimal spatial state of an antenna array for reception of the plurality of uplinks. Channel state information (CSI) is evaluated for each antenna in the antenna array. Determining the optimal spatial state of the antenna array includes using the CSI for each antenna to extrapolate the optimal spatial state of the antenna array for the plurality of uplinks. The method further includes changing a spatial state of the antenna array to the optimal spatial state.

    摘要： Example implementations are directed to methods and systems employing a solicited sounding protocol that includes receiving, by a second access point, a sounding trigger broadcast by a first access point. The methods and systems also include receiving, by the second access point, a dedicated training signal from a first station in response to the sounding trigger broadcast by the first access point, and generating, by the second access point, channel characteristics of a channel based on the first dedicated training signal, the channel including a forward channel between the second access point and the first station.
