Patent number: 12231987Abstract: This technology allows for determining the location of client devices via radio scanning for triggered orthogonal frequency-division multiple access (“OFDMA”) uplinks. Access points (“APs”) are configured for OFDMA transmissions. A first AP transmits a trigger frame on particular channel to stations in the wireless network. Neighboring APs scan channels for trigger frames (“TF”). Upon detection of a TF, neighboring APs associate a station identifier with a frequency allocation, or resource unit, in the TF. The neighboring APs receive an OFDMA uplink from the stations, determine a received signal strength indicator (“RSSI”) value for each frequency allocation in the OFDMA uplink, and transmit the RSSI values with the associated station identifier to the first AP. The first AP determines the location of each station by mapping a distance value to the RSSI values.Type: GrantFiled: December 20, 2021Date of Patent: February 18, 2025Assignee: Cisco Technology, Inc.Inventors: Matthew Aaron Silverman, John Matthew Swartz, Ardalan Alizadeh, Jerome Henry

Publication number: 20240380640Abstract: The present disclosure is directed to simultaneous channel sounding on multiple MLO channels followed by determining phase and amplitude corrections based on channel impulse responses obtained on each MLO channel. The corrections are then used in subsequent extrapolation of channel sounding on one channel to another. In one aspect, a method includes transmitting, on each radio interface of a first multi-link device, a corresponding sounding probe to a second multi-link device; determining, by each radio interface of the first multi-link device, a corresponding channel impulse response based on the corresponding sound probe to yield a plurality of channel impulse responses; determining an offset between the plurality of channel impulse responses; and using the offset during a subsequent extrapolation of a sounding probe on one radio interface to a second radio interface of the first multi-link device.Type: ApplicationFiled: July 21, 2023Publication date: November 14, 2024Inventors: Matthew Aaron Silverman, Malcolm Muir Smith, Brian Donald Hart, Indermeet Singh Gandhi, John Matthew Swartz

Publication number: 20240056226Abstract: A network of access points (AP) in a high-density environment may be provided. A number of packet transmission retries for one or more of the AP may be determined by setting a number, m, of retries for transmitting a data packet, where m is the upper limit of the number of retries. Data packets are then transmitted m times. Upon transmitting the data packet m times, a success probability SP(u,m) for transmission of the data packet, where u is the number of users, may be calculated. The transmission of the data packet may be repeated m?x times where x is an integer. Upon calculating the success probability for m?x times, a success probability SP(u,m?x) for transmission of the data packet may be calculated. If SP (u,m?x) is larger than SP(u,m) then x may be decreased by one and actions (b)-(f) may be repeated. If SP (u,m?x) is not larger than SP(u,m) then m?x may be set as the maximum number of retries for the data packet.Type: ApplicationFiled: August 9, 2022Publication date: February 15, 2024Applicant: Cisco Technology, Inc.Inventors: Ardalan ALIZADEH, Sivadeep Reddy KALAVAKURU, Matthew Aaron SILVERMAN, John Matthew SWARTZ
