Patent number: 8842651Abstract: An apparatus and method for access point groupings bridging tunneled traffic for a communication network, includes a first step of associating each access point with a location parameter. A next step includes grouping access points in accordance with the location parameter. A next step includes receiving a packet. A next step includes bridging the packet between Layer-2 tunnels of all access points that are part of a grouping.Type: GrantFiled: November 28, 2012Date of Patent: September 23, 2014Assignee: Motorola Solutions, Inc.Inventors: Jeelan Poola, Azif Ak, Somesh Agrawal, Channareddy Ireddy, Sukhdeep Singh Johar, Vijay Yadav, Senthilraj Shanmugavadivel, Sundaresan Sundaram

Patent number: 8837453Abstract: Methods and apparatus are provided for reliably transmitting data. A method comprises identifying a metric for a first frame of a plurality of frames, wherein the metric is indicative of decoding significance for the first frame among the plurality of frames. When the metric corresponds to a relatively high decoding significance, the method further comprises transmitting the first frame in accordance with an enhanced transmission scheme. When the metric corresponds to a relatively low decoding significance, the method further comprises transmitting the first frame in accordance with a default transmission scheme. The reliability of the enhanced transmission scheme is greater than the reliability of the default transmission scheme.Type: GrantFiled: May 28, 2009Date of Patent: September 16, 2014Assignee: Symbol Technologies, Inc.Inventors: Jeelan Poola, Somesh Agrawal, Ian Chakeres, Ravindra Guntur

Patent number: 8391240Abstract: A network is provided that includes a first WLAN infrastructure device (WID) that defines a first subnet, and a wireless client device (WCD) that is initially associated with the first WID. The WCD associates with a “current” WID when the wireless client device roams from the first subnet to a second subnet defined by the current WID. Upon successful association, the current WID unicasts a first IGMP query message (IGMPQM) to the WCD that has a MAC header including a destination MAC address that is set to a MAC address of the WCD.Type: GrantFiled: December 29, 2009Date of Patent: March 5, 2013Assignee: Symbol Technologies, Inc.Inventors: Kunal K.

Patent number: 8027248Abstract: An apparatus, network and techniques for minimizing wireless network downtime associated with a wireless switch failure are disclosed. Access ports are adopted to multiple wireless switches wherein one switch operates to exchange data and control traffic with the access port and remaining switches operate to exchange control traffic with the access port. In the event of a link failure between the wireless switch exchanging data and control traffic with the access port, the access port remains adopted to remaining switches and exchanges data and control traffic with one of the remaining switches.Type: GrantFiled: September 19, 2008Date of Patent: September 27, 2011Assignee: Symbol Technologies, Inc.Inventors: Karthikeyan Balasubramanian, Venkatesh Kannan, Shrijith Velayudhan, Vivek Krishnan, Somesh Agrawal
