  • Patent number: 10033596
    Abstract: A wireless mesh network is provided with equipment and methods for monitoring and enforcement of license terms. The network includes a plurality of wireless network nodes, a wireless access point, and a network manager in communication with the access point and with the network nodes via the access point. At least one of the network nodes and the access point includes license information embedded in the device hardware, and the network manager provides services to the wireless network subject to license terms determined based on the license information embedded within the network node or access point. Additionally, the network manager is in communication with a user application external to the network, and relays communication between the user application and the wireless network. The network manager modulates communications relayed between the user application and the wireless network subject to the license information embedded within the network node or access point.

  • Publication number: 20180160321
    Abstract: The stability of a channel in a wireless network is evaluated at a node. Upon transmitting a packet from the node on a network channel, a first counter associated with the channel is incremented. Upon receiving an acknowledgment packet responsive to the transmitted packet, a second counter associated with the channel is incremented. A stability metric for the channel is computed based on values stored in the first and second counters. Additionally, interference on a channel of the network is measured at a node. Upon determining that no packet is received during a predetermined time-period on the channel, a received signal strength (RSS) is measured on the channel at an end of the predetermined time-period. Alternatively, upon determining that a packet is received during the predetermined time-period on the channel, the RSS is measured on the channel following completion of the transmission of the packet on the channel.

  • Publication number: 20170055236
    Abstract: A mesh network system includes a plurality of network nodes, a network manager, and at least one access point. The network nodes communicate wirelessly with each other and the at least one access point of the mesh network system. The network manager manages operation of a wireless mesh network including the nodes and the at least one access point. The at least one access point communicates wirelessly with the network nodes, and provides a gateway between the wireless mesh network and the network manager. The at least one network access point is operative to synchronize its operation timing to an external clock, such as a UPS or UTC clock. Furthermore, in wireless mesh networks including multiple access points, the access points can synchronize their operation timing to each other, and can provide timing information to other access points and nodes in the network.

  • Publication number: 20160345317
    Abstract: A wireless mesh network system includes network nodes that operate in blink and canopy modes of operation. In operation, a network manager joins nodes operating in the canopy node to the network and allocates network bandwidth to the canopy nodes. The allocated bandwidth includes a first bandwidth allocated for transmitting and receiving data packets between canopy nodes that are joined to the network, and a second bandwidth allocation for receiving network joining messages from nodes that are not joined to the network. The second bandwidth allocation is also used for receiving data messages from nodes operating in the blink mode. Thus, in response to receiving a message that was transmitted from a blink node to a canopy node using the second bandwidth allocation, the network manager identifies the message as a data message and provides the data from the message to a host application.
