Publication number: 20130163685Abstract: A system and method for communicating information through a powerline medium including at least three conductors, where the transmitter transmits at least two signals onto the powerline medium and the receiver receives one or more signals from the powerline medium. The transmitter adjusts the power transmitted into the powerline medium in order to set the adjusted transmit power to a predetermined level, e.g., a level that ensures power radiated from the powerline medium does not exceed a regulatory limit. The process of adjusting the transmit power may take into account a functional relationship between the transmitted power and properties of the channel.Type: ApplicationFiled: June 14, 2012Publication date: June 27, 2013Applicant: QUALCOMM ATHEROS,INC.Inventors: Lawrence W.

Publication number: 20130160086Abstract: Functionality for secure client authentication and service authorization in a shared communication network are disclosed. A managing network device of a communication network causes a securely connected client network device to perform an account authorization process with an accounting network device in parallel with a service matching process with the managing network device and one or more service providers of the communication network. The managing network device executes the service matching process and securely matches the client network device with one of the service providers. The accounting network device executes the account authorizing process with the client network device and provides a service voucher to the managing network device authorizing one or more of the service providers to service the client network device. The managing network device transmits the service voucher to the matched service provider to prompt the matched service provider to service the client network device.Type: ApplicationFiled: June 19, 2012Publication date: June 20, 2013Applicant: QUALCOMM ATHEROS, INCInventors: Srinivas KATAR, Lawrence W.

Patent number: 8467369Abstract: In a network, some data are transmitted between stations during time slots in contention free periods. Selecting the time slots includes collecting timing information at some stations in the network. The timing information indicates the times of existing time slots used by stations whose transmissions can be reliably received by the station collecting the timing information. The timing information is distributed to other stations in the network. A new time slot for transmission between a first and a second station is selected based at least on timing information indicating the times of existing time slots used by stations whose transmissions can be reliably received by at least one of the first and second station.Type: GrantFiled: June 4, 2008Date of Patent: June 18, 2013Assignee: Qualcomm Atheros, Inc.Inventors: Lawrence W.

Publication number: 20130038424Abstract: An electric vehicle can be configured to execute an association procedure with one or more charging stations in a charging facility to securely connect to and receive electric power from one of the charging stations. The electric vehicle can broadcast one or more service matching messages to the charging stations and, in response, can receive attenuation information from one or more of the charging stations. The electric vehicle can analyze the attenuation information received from the charging stations to identify with which charging station the electric vehicle should associate (e.g., to determine which charging station should provide electric power to the electric vehicle). The electric vehicle can then associate with (and receive electric power from) the identified charging station.Type: ApplicationFiled: August 1, 2012Publication date: February 14, 2013Applicant: Qualcomm Atheros, Inc.Inventors: Srinivas Katar, Lawrence W.

Publication number: 20130024706Abstract: Power save proxy functionality can be implemented to enable power save devices to switch to a power save mode and still receive communications from legacy communication devices. A first communication device determines that a second communication device is in a power save mode. The first communication device designates itself as a power save proxy for the second communication device that is in the power save mode. In response to detecting packets that are transmitted from a legacy communication device to the second communication device, the first communication device transmits a control message to the second communication device to request the second communication device to exit the power save mode, transmits a hold control message to the legacy communication device to request the legacy communication device to temporarily stop transmitting packets to the second communication device, or stores the packets intended for the second communication device.Type: ApplicationFiled: December 22, 2011Publication date: January 24, 2013Applicant: Qualcomm Atheros, Inc.Inventors: Srinivas Katar, Lawrence W.

Patent number: 8295301Abstract: Communication systems that use different physical layer (PHY) protocols can coexist on a communication medium (e.g., a powerline medium) by using an Inter-PHY Protocol (IPP). The different protocols may use different signal modulation schemes but still may have some features in common. The IPP includes a resource sharing mechanism that regulates access to the communication medium by devices functioning as communication devices (for example, devices communicating over a power line). A subset of devices that communicate among each other form a logical network that shares the medium with other logical networks that use either the same PHY protocol or a different PHY protocol.Type: GrantFiled: June 16, 2009Date of Patent: October 23, 2012Assignee: Qualcomm Atheros, Inc.Inventors: Lawrence W.
