  • Patent number: 12035225
    Abstract: Examples described herein provide multi-band channel scanning. Examples may include transmitting, by a first radio of a first network device operating at a first frequency band below the millimeter-wave (mmWave), a beacon frame indicating a particular scanning channel of a second frequency band within the mmWave, receiving, by a second radio of the first network device operating the second frequency band, a probe request from a second network device via the particular scanning channel, wherein the probe request is in response to the beacon frame received by the second network device, and in response to the probe request, transmitting, by the second radio of the first network device, a probe response in each of one or more sector transmitting directions via the particular scanning channel.

  • Patent number: 11881946
    Abstract: Systems and methods for improving the performance and stability of bonding radios are provided. One method includes receiving a packet from a client device. Next, the method includes determining whether the received packet is an expected next packet and transmitting the received packet to a next destination if the received packet is the expected next packet. In an event the received packet is not the expected next packet, transmitting the received packet to a queue, setting a timer to wait for the expected next packet, and transmitting a message to the sender of the received packet requesting that the expected next packet be sent.

  • Patent number: 11405775
    Abstract: Some examples relate to use of a three-address scheme for forwarding frames in a wireless mesh network (WMN). In an example, a node in a WMN may receive an Ethernet packet from a station outside of the WMN. The Ethernet packet may include a first address scheme comprising a destination address (DA) field, and a source address (SA) of the Ethernet packet. The Ethernet packet may be encapsulated in a second Ethernet packet comprising second address scheme. The second Ethernet packet may be encapsulated in an IEEE 802.11 frame comprising a third address scheme.

  • Patent number: 10932157
    Abstract: Techniques and systems perform link aggregation and fault tolerance across a wireless link connecting two wired networks. In a first example, a wireless networking device includes first radio and a second radio communicatively coupled to a wired network communication interface. The first and second radios have different operational parameters for bandwidth of transmission and other factors. The wireless networking device may include a processing device to cause the wireless networking device to establish a single data communication channel via the first radio; determine throughput of communication has been affected by an impact condition causing communication via the first radio to be impacted negatively and the second radio impacted positively. Based on that determination the single data communication channel may be transitioned to be received via the second radio. Each radio may maintain an active/backup status or perform load balancing to provide transmission of the single data communication channel.

  • Publication number: 20150081420
    Abstract: A computer-implemented method for identifying relationships between online content items uses a computing device including a processor and a memory. The method includes identifying a first content item and identifying a plurality of occurrence results for the first content item. Each occurrence result of the plurality of occurrence results includes an indicator that the first content item was retrieved along with a list of other content items based on an online activity of at least one user device. The method also includes computing a number of co-occurrence events involving the first content item and a second content item from the plurality of occurrence results. Each co-occurrence event includes an indicator that both first content item and second content item were retrieved together in an occurrence result. The method further includes computing a relationship value between first content item and second content item using at least the number of co-occurrence events.
