Patent number: 7664955Abstract: A method for establishing shared information is described. The method includes estimating characteristics of a communication channel between two nodes based on signals transmitted between the nodes. The method also includes transmitting a signal from the first node to the second node, the signal being modulated with a first data sequence according to a first estimated characteristic, and transmitting a signal from the second node to the first node, the signal being modulated with a second data sequence according to a second estimated characteristic. Shared information is formed at each of the first and second nodes based on at least a portion of the first data sequence and at least a portion of the second data sequence.Type: GrantFiled: July 10, 2006Date of Patent: February 16, 2010Assignee: Atheros Communications, Inc.Inventors: Richard E. Newman, Lawrence W. Yonge, III

Patent number: 7660327Abstract: A method of operating in a network in which a plurality of stations communicate over a shared medium (e.g., using a carrier sense multiple access (CSMA) service). The stations contend for access to the shared medium using a contention procedure that relies on a priority level, wherein transmissions with a lower priority level have a reduced chance of gaining access to the shared medium during a contention process. Selected stations are given the capability of temporarily promoting the priority level of transmissions they are attempting to make. The priority level is increased during an interval to reduce the chance that other stations gain access to the shared medium during that interval, and the priority level is restored to its normal level following the interval.Type: GrantFiled: February 3, 2004Date of Patent: February 9, 2010Assignee: Atheros Communications, Inc.Inventors: Srinivas Katar, Lawrence W. Yonge, III

Patent number: 7636370Abstract: Methods of operating in a network in which a plurality of stations communicate over a shared medium and contend for access during a priority resolution period. At least some of the stations use a first CSMA network protocol having certain characteristics (e.g., some transmissions have a format that includes a start of frame delimiter (SOF), a payload, and an end of frame delimiter (EOF), wherein the SOF and EOF each contain sufficient information to permit a station receiving only one of the SOF and EOF to determine the start of a priority resolution period). And at least some stations use a second network protocol capable of coexisting with the first protocol, so that stations may communicate using either the first or second protocol. The second protocol may have various characteristics configured to achieve coexistence with the first protocol (e.g., transmissions that have a format that includes an SOF but not an EOF).Type: GrantFiled: March 3, 2005Date of Patent: December 22, 2009Assignee: Intellon CorporationInventors: Lawrence W. Yonge, III, Srinivas Katar

Publication number: 20090116461Abstract: 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: ApplicationFiled: June 4, 2008Publication date: May 7, 2009Applicant: Intellon CorporationInventors: Lawrence W.

Publication number: 20090034552Abstract: Systems and methods for dynamic allocation of network bandwidth. In some examples, a guaranteed interval period, including a guaranteed interval start time and guaranteed interval end time, can be identified based upon policy. Network stations can then identify first interval start times and first interval end times different than the guaranteed start times and guaranteed end time provided by policy. An access network can thereby provide a first interval start time and a first interval end time to stations within the access network. An in-home network can determine an in-home interval period based upon the first interval start time and first interval end time.Type: ApplicationFiled: June 4, 2008Publication date: February 5, 2009Applicant: Intellon CorporationInventors: Lawrence W.
