Patent number: 8451752Abstract: A mobile device communicates with a first mesh access point (AP) via a first radio frequency (RF) interface of the mobile device over a first wireless connection, where the first mesh AP is one of mesh APs of a first mesh cell of the wireless mesh network. It is detected that signal quality of the first wireless connection drops below a predetermined threshold as the mobile device moves from the first mesh cell towards a second mesh cell. In response to the detection, it is established via a second RF interface of the mobile device a second wireless connection with a second mesh AP of a second mesh cell of the wireless mesh network, while concurrently maintaining the first wireless connection with the first mesh AP via the first RF interface.Type: GrantFiled: June 22, 2010Date of Patent: May 28, 2013Assignee: Arrowspan, Inc.Inventor: Wenchen Lu

Patent number: 8121053Abstract: Techniques for providing multi-radio wireless mesh network solutions are described herein. According to one embodiment, routing information of neighboring mesh APs is monitored via a dedicated monitoring antenna of a current mesh access point (AP). The current mesh AP is one of mesh APs of a wireless mesh network, each having an uplink antenna, a downlink antenna, a local link antenna, and a monitoring antenna. Traffic of an uplink antenna of the wireless mesh AP is dynamically reconfigured and rerouted from a first routing path coupled to a first uplink mesh AP to a second routing path coupled to a second uplink mesh AP, if the second routing path has a better routing condition than the first routing path based on the monitored routing information associated with the first uplink mesh AP and the second uplink mesh AP. Other methods and apparatuses are also described.Type: GrantFiled: May 21, 2009Date of Patent: February 21, 2012Assignee: ArrowSpan, Inc.Inventor: Wenchen Lu

Patent number: 7912063Abstract: Techniques for secure communications among wireless mesh network access points are described herein. According to one embodiment, a wireless mesh network includes multiple wireless mesh access points communicatively coupled to each other via multiple mesh links and multiple end-user clients, each being associated with one of the wireless mesh access points. In response to a packet received at a first mesh access point of the wireless mesh access points from a local end-user client of the first mesh access point destined to another end-user client associated with a second mesh access point of the wireless mesh access points, the packet is routed via a tunneling protocol from the first mesh access point to the second mesh access point. Other methods and apparatuses are also described.Type: GrantFiled: May 21, 2008Date of Patent: March 22, 2011Assignee: ArrowSpan, Inc.Inventor: Wenchen Lu

Patent number: 7773542Abstract: A dual radio wireless mesh access point is described herein. According to one embodiment, a wireless mesh access point includes an uplink wireless interface, a downlink wireless interface, a local wireless interface, and a routing unit coupled to the uplink, downlink, and the local wireless interfaces. The routing unit is configured to route data packets to other wireless mesh access points (APs), including communicating with an uplink AP via the uplink wireless interface and communicating with a downlink AP via the downlink wireless interface. The uplink and downlink wireless interfaces utilize different communication channels having different communication frequencies. The routing unit communicates with one or more local clients via the local wireless interface. Other methods and apparatuses are also described.Type: GrantFiled: May 21, 2008Date of Patent: August 10, 2010Assignee: ArrowSpan, Inc.Inventor: Wenchen Lu
