Patent number: 11743775Abstract: Systems and methods herein can analyze a bandwidth restriction in a communication stream of an Access Point (AP). Then, based on the bandwidth restriction, the AP can determine a lower amount of wireless bandwidth to provide to station wireless communicating to the AP. The AP can then modify a bandwidth allocation assigned to the station based on the lower amount of wireless bandwidth.Type: GrantFiled: April 4, 2022Date of Patent: August 29, 2023Assignee: Cisco Technology, IncInventors: Vishal Satyendra Desai, Benjamin Jacob Cizdziel, Pooya Monajemi, Young Il Choi, Santosh Babaji Kulkarni

Patent number: 11716632Abstract: Coordinated Frequency Division Multiplexing (FDM) Transmission Opportunity (TXOP) sharing may be provided by determining that at least two Access Points (APs) of a wireless network support coordinated FDM TXOP sharing. In response to the determination that the at least two APs support coordinated FDM TXOP sharing, at least one of: a first bias is applied to a channel assignment algorithm to promote an assignment of overlapping channels of the at least two APs, and a second bias is applied to the channel assignment algorithm to promote an assignment of adjacent channels of the at least two APs. Next, channels are assigned to the at least two APs based on an output of the channel assignment algorithm.Type: GrantFiled: June 2, 2021Date of Patent: August 1, 2023Assignee: Cisco Technology, Inc.Inventors: Benjamin Jacob Cizdziel, Pooya Monajemi, Santosh Babaji Kulkarni, Vishal Satyendra Desai

Publication number: 20230217258Abstract: Dynamic configuration of Overlapping Basic Set Service Preamble Detect (OBSS/PD) parameters for an Access Point (AP) may be provided. First, a plurality of stations within a Spatial Reuse (SR) range of the AP may be determined. Next, Signal to Interference plus Noise Ratio (SINR) calculations associated with the plurality of stations may be performed to determine an SINR impact on the plurality of stations if the AP performs an SR transmission given OBSS/PD parameters currently configured for the AP. Then, based on the SINR calculations, the OBSS/PD parameters for the AP may be dynamically adjusted.Type: ApplicationFiled: March 15, 2023Publication date: July 6, 2023Applicant: Cisco Technology, Inc.Inventors: Pooya MONAJEMI, Benjamin Jacob CIZDZIEL, Vishal Satyendra DESAI

Patent number: 11671945Abstract: In dense Wireless Local Area Network (WLAN) deployments, Access Points (APs) in other Extended Service Sets (ESSs) can be hidden (a first AP does not receive signals from a third AP). However, these APs in other ESSs can still interfere with communications between the third AP and the devices communicating with the first AP. To improve service to that device in that situation, the first AP needs information about the third AP in the first AP's decision making processes. In these situations, a second AP, in contact with the third AP, can share information about the third AP with the first AP so that the first AP can avoid colliding with the third AP.Type: GrantFiled: November 30, 2021Date of Patent: June 6, 2023Assignee: Cisco Technology, Inc.Inventors: Pooya Monajemi, Vishal Satyendra Desai, Benjamin Jacob Cizdziel, Santosh Babaji Kulkarni, Young Il Choi

Patent number: 11647524Abstract: Bypassing radar in wide Dynamic Frequency Selection (DFS) channels utilizing puncturing may be provided. A first client device may be classified as eligible for puncturing and a second client device may be classified as not eligible for puncturing. Next, it may be determined that a subchannel in a bandwidth range should not be used. Then, in response to determining that the subchannel in the bandwidth range should not be used, the first client device may be steered to a first subset of the bandwidth range and the second client device may be steered to a second subset of the bandwidth range. The second subset of the bandwidth range may be smaller than the first subset of the bandwidth range.Type: GrantFiled: November 8, 2021Date of Patent: May 9, 2023Assignee: CISCO TECHNOLOGY, INCInventors: Benjamin Jacob Cizdziel, Brian D.

Patent number: 11510210Abstract: Management of radio resources of a wireless network according to a Flexible Radio Assignment (FRA) mode may be provided. For each Access Point (AP) of the wireless network: a type of AP may be identified including determining whether each AP has Multi-Link (ML) capability, and when the FRA mode is for performance, a bias may be applied to each ML capable AP to reduce a likelihood of a radio of each ML capable AP being identified as a redundant radio.
