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.

Abstract: Systems and methods for pairing-less device connectivity are disclosed. For example, a group of primary devices are authorized to establish a non-bonded connection with a given secondary device. When the secondary device is in proximity of at least one of the group of primary devices, that primary device may receive a wireless beacon from the secondary device. The system may identify the primary device as an authorized device, perform user presence confirmation processes, and send a command to the primary device to establish the non-bonded connection. Encryption using a network layer or a presentation layer and an application layer of a computer network, instead of a link layer, is utilized for secure data transmission over the non-bonded connection.
