  • Patent number: 10568160
    Abstract: In one embodiment, a method implemented on an access point of a wireless communication system includes: determining an estimate for a relative velocity between a mobile wireless client device and the access point, the mobile wireless client device communicating wirelessly with the access point over a channel; determining a channel coherence time for the channel using said estimated relative velocity; and determining a maximum aggregated frame size based on the determined channel coherence time.
    Type: Grant

  • Patent number: 10524272
    Abstract: In one embodiment, a control device associated with a wireless network of a given location determines a reference quality of location readings between access points and client devices based on using substantially all of an available wireless communication bandwidth. The control device may then determine channel state information (CSI) between the client devices and access points for each orthogonal frequency-division multiple access (OFDMA) resource unit (RU), and selects a subset of RUs for allocation to each respective client device, based on the subset of RUs allocated to each respective client device i) surpassing a determined threshold of certain parameters of the CSI, while also ii) providing a minimum quality of a location reading based on using only the subset of RUs as compared to the reference quality of location readings. The control device may then allocate the selected subset of RUs to each respective client device for location-preserving OFDMA-signaling-based communication.

  • Publication number: 20180302939
    Abstract: In one embodiment, a method implemented on an access point of a wireless communication system includes: determining an estimate for a relative velocity between a mobile wireless client device and the access point, the mobile wireless client device communicating wirelessly with the access point over a channel; determining a channel coherence time for the channel using said estimated relative velocity; and determining a maximum aggregated frame size based on the determined channel coherence time.
