Patent number: 11470579Abstract: Embodiments herein describe using a dual assess point (AP) to establish two access points that both are established by two individual radios (e.g., two 5 GHz radios). Generally, APs experience highly degraded performance when two co-located radios operate within the same band. In one embodiment, AP devices can deploy same band radios using a macro-micro cell approach. Thus, the AP may intelligently hand off client devices between the micro and macro cell in a way that optimizes the system for overall throughput and low packet latency while creating minimal oscillation of clients between cells. The embodiments in this disclosure disclose techniques that direct clients in a manner that optimizes these factors.Type: GrantFiled: October 9, 2020Date of Patent: October 11, 2022Assignee: Cisco Technology, Inc.Inventors: Vishal Satyendra Desai, John Blosco, Allen Huotari

Patent number: 10340975Abstract: Receiving filter design that reduces out-of-channel interference for APs is disclosed. An AP includes a first radio and a second radio disposed in a body of the AP. The first radio transmits first signals in a frequency band while the second radio receives second signals in the same frequency band. The AP includes an interference mitigation controller that determines a receiving filter for the second radio to mitigate interference between the first radio and the second radio based on the second signals received by the second radio when the first radio transmits the first signals in the frequency band. The interference mitigation controller applies the receiving filter to signals received by the second radio during a time period that the first radio is transmitting signals in the frequency band while the second radio is receiving signals in the frequency band.Type: GrantFiled: December 15, 2016Date of Patent: July 2, 2019Assignee: Cisco Technology, Inc.Inventors: Matthew A.

Patent number: 9332557Abstract: In a wireless local area network, each of multiple access points, in a high density deployment, are configured to suppress co-channel interference. A first access point having a plurality of antennas beamforms a transmission to a wireless client device within a null-space or with the weakest singular eigenmodes of a wireless channel between the first access point and at least one co-channel second access point. Techniques are presented herein for situations in which any given access point has two or more co-channel access points. In addition, an access point may perform receive side suppression with respect to a transmission (made by a co-channel access point to one of its associated wireless client devices) that is received from that co-channel access point.Type: GrantFiled: January 20, 2015Date of Patent: May 3, 2016Assignee: Cisco Technology, Inc.Inventors: Paul J.

Patent number: 8971443Abstract: Techniques are presented to reduce the number of antennas used for a transmission for a given antenna configuration and data rate. At a wireless communication device having a plurality of antennas and capable of sending a transmission via one or more of the plurality of antennas, a determination is made of a data rate and antenna configuration to be used for a transmission. A comparison is made between a total transmit power for a minimum number of antennas for the data rate to be used for the transmission and a total transmit power associated with the antenna configuration for the transmission. When the total transmit power for a minimum number of antennas for the data rate is greater than the total transmit power associated with the antenna configuration for the transmission, the transmission is sent with the minimum number of antennas.Type: GrantFiled: February 28, 2013Date of Patent: March 3, 2015Assignee: Cisco Technology, Inc.Inventors: John Blosco, James Friedmann, Greg Corsetto
