Abstract: A first network device wirelessly transmits announcement messages in quick succession over multiple channels that represent normal operating channels of other network devices. The other network devices receive one of the announcement messages over their respective operating channels, and then send a message to one or more servers indicating that one of the announcement messages has been received. Various parameters and information related to the received announcement message, such as RSSI, SNR, and the contents of the announcement message, are included in the message sent to the one or more servers by each of the other network devices. The one or more servers then incorporate information in the messages sent from the other network devices into a network connectivity graph or table.
