    摘要: A method including selecting multiple dedicated radios on a transmission channel and programming multiple association identifiers on each dedicated radio is provided. Each of the association identifiers is configured to detect a resource unit assigned to one of multiple stations. The method includes providing multiple packets collected from the dedicated radios to a server and merging the packets from the dedicated radios to identify at least one station. Merging the packets includes identifying a preamble in the packets from the dedicated radios, matching the preamble from different dedicated radios, combining a data portion of the packets from different dedicated radios whose preamble match, selecting a time-stamp from one of the dedicated radios, and associating the time-stamp with the data portion. A system and a non-transitory, computer readable medium storing instructions to perform the above method are also provided.

    摘要: A method for identifying a client device in a network, and a first radio in the network that is coupled with the client device is provided. The method includes determining one or more sequences of roaming events for multiple client devices in the network, evaluating a performance metric for a roaming event and evaluating an interaction between the client device and one or more radios involved in the roaming events for the plurality of client devices. The method also includes selecting a second radio in the network based at least in part on (1) the one or more sequences of roaming events, (2) the performance metric, and (3) the interaction between the client device and the one or more radios, and recommending switching the client device from the first radio to the second radio. A system and a predictive tool to perform the above method are also provided.
