  • Patent number: 10368360
    Abstract: A WAP including: a non-volatile memory, an event detection circuit and a rule initiation circuit. The non-volatile memory stores network event rules each of which tags a station to monitor and actions to initiate for a targeted device if the tagged station undergoes a network event. The event detection circuit monitors each wireless station for a transition in communication status corresponding to a network event, and identifies the wireless station and the network event. The rule initiation circuit determines whether the identified station and network event corresponds with one of the network event rules for the identified station in the non-volatile memory, and in the event of a match, initiates the action prescribed for the corresponding targeted device.

  • Patent number: 10342052
    Abstract: A WAP including: a non-volatile memory, a proximity circuit, a connectivity circuit, and a prediction circuit. The non-volatile memory accumulates historical records of each station's proximity to the WAP including transitions in proximity over time along with corresponding connectivity options before and after each transition. The proximity circuit detects a transition in proximity to the WAP of an identified station. The connectivity circuit determines current connectivity options for communicating with the station. The prediction circuit correlates the accumulated historical records for the identified station which match the identified station's current proximity to the WAP with remaining historical records for the identified station to determine which of the remaining records exhibits the highest probability of predicting the identified station's subsequent proximity.

  • Patent number: 10298299
    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.
