  • Patent number: 9693204
    Abstract: The present disclosure discloses a system and a method for conveying information using broadcast frames. Specifically, a network device detects a first wireless signal comprising a beacon frame transmitted by an access point in a network. The network device then identifies a radio Frequency (RF) channel indicated in the beacon frame. Responsive to identifying the RF channel in the beacon frame, the network device selects the RF channel to convey information to one or more network elements using a broadcast frame. Moreover, the network device transmits the broadcast frame to the one or more network elements. Note that, the broadcast frame includes information corresponding to a detected second wireless signal.

  • Publication number: 20110191827
    Abstract: Detecting rogue access points (APs) or rogue router APs on the wireless network. An authorized access point (AAP) on a network collects wired MAC addresses of wired devices in its subnet, and also collects BSSIDs of wireless devices operating in its vicinity. A rogue is detected by correlating the OUI portion of MAC addresses and BSSIDs after filtering out authorized OUIs.

  • Publication number: 20110030055
    Abstract: Detecting spoofing in a digital network. Packets of information in a digital network using a shared medium contain a unique identifier for the device originating the packet. An individual device may be transmitting, or receiving, but not both. If a device receives a packet containing its unique identifier as the origin address, that packet must have been transmitted by another device, and a spoofing alert is raised.
