Patent number: 9007975Abstract: An access point including a beacon module that determines a beacon interval and that defines a first portion and a second portion of the beacon interval during which the access point operates in a normal mode and a power save mode, respectively. On receiving a communication from a client station during the first portion, a control module does not transition the access point from the normal mode to the power save mode at an end of the first portion. If the communication is not received during the first portion, the control module transitions the access point from the normal mode to the power save mode at the end of the first portion and from the power save mode to the normal mode at an end of the second portion. A duration of the second portion is less than a scan time of the client station.Type: GrantFiled: October 31, 2013Date of Patent: April 14, 2015Assignee: Marvell World Trade Ltd.Inventors: Milind Kopikare, Raja Banerjea, Paul A.

Patent number: 8954502Abstract: A first message is received that includes a value indicative of a first timeout interval associated with configuring a second device to operate as a peer-to-peer (P2P) group owner or a P2P client in a P2P wireless network. A second timeout interval is determined based at least on the first timeout interval, and it is determined whether the second timeout interval expired. It is determined whether a second message is received from the second device prior to the second timeout interval expiring, and it is determined that a P2P connection with the second device failed based on a determination that the second message was not received from the second device prior to the second timeout interval expiring.Type: GrantFiled: August 6, 2010Date of Patent: February 10, 2015Assignee: Marvell International Ltd.Inventors: Milind Kopikare, Sarang Shrikrishna Wagholikar, Raja Banerjea

Patent number: 8923847Abstract: A network interface including a radio frequency system with a component configured for communication with an access point. First, second and third client modules communicate with the access point according to respective wireless communication standards. The first, second and third client modules share the component, such that during respective periods the first, second and third client modules communicate with the access point via the component. The first client module transmits a request signal to the second client module while the second client module is in an idle state and the third client module is in an active state. The request signal requests access to the component. The third client module, in response to the request signal, aborts transmitting of first data to the access point and transmits an acknowledgement signal. The first client module transmits to or receives from the access point second data based on the acknowledgement signal.Type: GrantFiled: December 10, 2013Date of Patent: December 30, 2014Assignee: Marvell World Trade Ltd.Inventors: Raja Banerjea, Sandesh Goel, Milind Kopikare

Patent number: 8891492Abstract: Techniques for establishing a dynamic ad-hoc wireless network are disclosed. A node transitions between wake and sleep modes during periods defined as beacon intervals. Before a network connection is established and while it is awake, the node transmits network connection request and also listens for network activity. If a beacon or response message is not detected while the node is listening, the node enters sleep mode and thereby conserves power. The node optionally changes the duration of its detection period and/or the time at which it listens for network activity relative to the start of each beacon interval. Information elements are optionally included with transmitted beacons or response messages.Type: GrantFiled: July 30, 2012Date of Patent: November 18, 2014Assignee: Marvell International Ltd.Inventors: Rahul Kopikare, Milind Kopikare, Kapil Chhabra

Patent number: 8886833Abstract: A network interface comprises a random or pseudo-random number generator. The network interface determines that a first communication device is group owner of a peer-to-peer (P2P) group, and randomly or pseudo-randomly generates a media access control (MAC) address for the first communication device using the random or pseudo-random number generator. The network interface utilizes the randomly or pseudo-randomly generated MAC address for the first communication device in group owner communications with one or more second communication devices in the P2P group.Type: GrantFiled: June 24, 2010Date of Patent: November 11, 2014Assignee: Marvell International Ltd.Inventors: Milind Kopikare, Paul A.

Publication number: 20140258550Abstract: A device previously configured as a registrar and that has established an independent ad-hoc network is automatically discovered by another device also previously configured as a registrar. To form an ad-hoc wireless network between these two devices, each device periodically enters a scanning mode to scan for and intercept beacons transmitted by the other device. Upon such interception, one of the devices becomes an enrollee in accordance with a predefined condition and in response to a user selected option. Subsequently, the enrollee modifies its beacons to include an attribute, such as the MAC address, associated with the other device. After intercepting the modified beacon, the remaining registrar prompts it user to decide whether to allow the enrollee to join the registrar's network. If the user responds affirmatively, a handshake is performed between the two devices and a subsequent attempt is made by the enrollee to join the registrar's network.Type: ApplicationFiled: May 19, 2014Publication date: September 11, 2014Applicant: Marvell International Ltd.Inventors: Kapil Chhabra, Rahul Kopikare, Milind Kopikare

Patent number: 8798562Abstract: A system and method are disclosed for controlling transmit power amplification in a wireless transmitting device. A processor receives data to determine whether a communication channel from a transmitting device to a receiving device is strong enough to support a target data transmit rate of the devices with a power amplifier either on or off. The processor controls a switching device between a data transmitter circuit and the transmitter's antenna based on the quality of the communication channel. In a first state, the switching device connects the data transmitter circuit to the power amplifier to increase the strength of the signal communicated to the antenna. In a second state, the switching device bypasses the power amplifier. The power amplifier is turned off when the switch is in the second state, thereby decreasing the power consumed by the transmitting device as it transmits data at the target data transmit rate.Type: GrantFiled: June 6, 2013Date of Patent: August 5, 2014Assignee: Marvell International Ltd.Inventors: Milind Kopikare, Partho Mishra
