  • Patent number: 11916624
    Abstract: A wireless network includes a networking device and various stations. The networking device determines an available bandwidth of each station of the wireless network. Further, the networking device assigns a bandwidth and at least one spatial stream to each station. The bandwidth assigned to each station is less than or equal to the available bandwidth of the corresponding station. Further, the bandwidth assigned to one station is different from and partially overlaps with the bandwidth assigned to another station. Similarly, the spatial stream assigned to one station is different from the spatial stream assigned to another station. The networking device generates a data packet indicative of the bandwidth and the spatial stream assigned to each station of the wireless network, and transmits the data packet to each station to enable multi-user multiple-input-multiple-output (MU-MIMO) communication between the networking device and the stations.

  • Patent number: 11917656
    Abstract: An access point device operable in a wireless network detects multi-band capability of a wireless client based on a probe request received from the wireless client on the non-preferred communication band. The multi-band capability is detected based on a set of parameters included in the received probe request. When the wireless client is detected to have the multi-band capability, the access point device blocks the attempt of the first wireless client to associate on the non-preferred communication band. The access point device allows the wireless client to associate on one of the non-preferred communication band and a preferred communication band based on a count of probe requests received by the access point device from the wireless client on the non-preferred communication band. Upon association on the non-preferred communication band, the access point device steers the associated wireless client to the preferred communication band.
