Abstract: Approaches are described for accurate spatial diagnostics data and channel state information (CSI) recording due to dynamic bandwidth selection and other network changes in a wireless local area network (WLAN). Data transmissions such as channel soundings of a network, including data communications between networked computing devices on a communication channel of the network, can be obtained. The data communications can be associated with channel state parameters that can describe characteristics of the channel through which data is transmitted. The channel state parameters can be monitored overtime to detect a trigger event on the network. A type of trigger event can be determined based on channel state parameters before and after the event. Optimization parameters (e.g., operation parameters, calibration parameters, etc.) or other such information can be determined based on the type of trigger event.

Abstract: A multiple-input multiple-output (MIMO) wireless transceiver with “N” transmit and receive chains and a bandwidth evaluation circuit, a chain partitioning circuit and a switchable radio frequency ‘RF’ filter bank. The bandwidth evaluation circuit evaluates both the utilization of the WLAN(s) and any remaining communications channels and determines whether to operate the MIMO chains synchronously as a single radio or asynchronously as multiple radios. The chain partitioning circuit either partitions subsets of the MIMO chains for asynchronous operation as distinct radios or combines all MIMO chains for synchronous operation as a single radio. The switchable RF filter bank is responsive to a partitioning of subsets of the chains into distinct radios to add RF filters to a RF portion of the chains to isolate each radio from one another, and responsive to a combining of all MIMO chains into a single radio to remove all RF filters.
