Patent number: 9538417Abstract: Quality of service for mesh networks is described. In embodiment(s), communication data can be prioritized as priority data and/or non-priority data for communication from a source node to a destination node in a mesh network. A first route in the mesh network can be determined to communicate the priority data from the source node to the destination node based on a minimum number of intermediate nodes via which the priority data is communicated. Additionally, a second route in the mesh network can be determined to communicate the non-priority data from the source node to the destination node based on a highest bit rate to communicate the non-priority data. A time duration to communicate the priority via the first route is less than a time duration to communicate the non-priority data via the second route.Type: GrantFiled: September 30, 2013Date of Patent: January 3, 2017Assignee: Marvell International Ltd.Inventors: Ronak Anjan Chokshi, Ashish Kumar Shukla, Rajesh Shreeram Bhagwat

Patent number: 9532311Abstract: In response to determining that a Bluetooth inquiry phase or the Bluetooth paging phase will begin, a power save indicator signal is sent from a first communication device to a second communication device prior to a start of the Bluetooth inquiry phase or the Bluetooth paging phase. A gap between a first Bluetooth communication slot and a second Bluetooth communication slot is determined, and a time period within the gap is determined, where an end of the time period occurs at a defined amount of time prior to a start of the second Bluetooth communication slot. During the time period, one or more power save poll messages are sent from the first communication device to the second communication device, each first power save poll message prompting the second communication device to transmit a respective first WLAN packet to the first communication device.Type: GrantFiled: August 24, 2015Date of Patent: December 27, 2016Assignee: Marvell International Ltd.Inventors: Kapil Chhabra, Zhenyu Zhang, Milind Kopikare, Deepak Jain, Robert Mack, Gladys Yuen Yan Wong, Li-Fu Jeng, Ronak Anjan Chokshi
