Patent number: 8189551Abstract: Devices, networks and methods relating to routing gateway traffic in a mesh network for wireless access. A mesh network has multiple nodes in at least one gateway node through which all incoming and outgoing data traffic pass through. The nodes provide wireless access to wireless and user devices, each of which is associated with a node in the mesh network. Each gateway node contains a record detailing which nodes are providing wireless access to which wireless end user device and which nodes are associated with which end user devices. This record of each end user device's location is periodically updated as the gateway node periodically receives data from the nodes which detail the device is being serviced by which node. Any incoming data traffic destined for an end user device is encapsulated and routed to the proper node servicing that end user device.Type: GrantFiled: May 12, 2009Date of Patent: May 29, 2012Assignee: BelAir Networks Inc.Inventors: Stephen G.

Patent number: 8009562Abstract: Networks, devices and methods related to wireless networking. A wireless network using nodes that perform both distribution and backhaul functions is provided. These nodes constitute the key elements of a wireless network that would be deployed and controlled by a wireless network operator. Each node contains a distribution wireless module which is wirelessly coupled to the wireless end user device using a point to multipoint scheme. Also integrated into each node is at least one backhaul wireless module with a directional wireless antenna. Each backhaul wireless module communicates by way of a point to point wireless link with the backhaul module of one other node. The nodes in the wireless network are interconnected to form a mesh backhaul network. Because of the nature of a mesh network, data traffic can be routed around obstacles that may prevent line of site links. Furthermore, the mesh network allows dynamic routing of data traffic to avoid congestion points or downed links in the network.Type: GrantFiled: February 19, 2010Date of Patent: August 30, 2011Assignee: BelAir Networks Inc.Inventors: Stephen G.

Patent number: 7821958Abstract: A system and method is provided for estimating the T1 timing error and clock recovery errors by processing timing information from the associated pseudowire packet stream(s) from which the T1 is derived. The timing errors are presented as MTIE measurements which are used to present alarms for a Network Operation Control centre and are used to accurately alarm error conditions where the regenerated or derived T1 signal does not meet MTIE or clock accuracy errors. This alarm is intended to detect conditions of excessive packet jitter, wander or phase transients which may exist in the data network over which the pseudowire stream is transported. In another aspect, the errors are used to control the regeneration of the T1 clock information.Type: GrantFiled: December 21, 2007Date of Patent: October 26, 2010Assignee: BelAir Networks Inc.Inventors: Roland A.

Patent number: 7660559Abstract: Methods and devices related to wireless networking. A wireless device has multiple directional antennas and multiple backhaul radio modules which provide point to point wireless links with other wireless devices. Each radio module can use any one of the available directional antennas to link to one other routing device. Antennas are automatically selected for each wireless device by merely setting one device in a “hunt” mode and setting another device in a “listen” mode. Devices in a hunt mode cycle through the available antennas by sequentially transmitting transmit messages to devices in the listen mode using each of the available antennas in turn. Devices in the listen mode also cycle through their available antennas by sequentially “listening” for transmit messages. A listen mode device, receives transmit messages on each of its available antennas, and, after gathering the relevant data, determines which of its antennas is best suited for communicating with the hunt mode device.Type: GrantFiled: December 11, 2006Date of Patent: February 9, 2010Assignee: Belair Networks Inc.Inventors: Bernard Herscovich, Stephen G.
