Publication number: 20140328416Abstract: A network device can be configured to dynamically adapt its current primary receiver coupling to channel conditions. For each of a plurality of transmitting network devices, the network device can determine a potential primary receiver coupling of the first network device for receiving communications from the transmitting network device based, at least in part, on a performance measurement associated with each of the plurality of communication channels between the network device and the transmitting device. The network device can select its current primary receiver coupling based, at least in part, on the potential primary receiver couplings determined for the plurality of transmitting network devices. In addition, the network device can also determine how to communicate with a receiving network device based, at least in part, on a preferred communication channel between the two network devices and a current primary receiver coupling of the receiving network device.Type: ApplicationFiled: May 6, 2013Publication date: November 6, 2014Applicant: QUALCOMM IncorporatedInventors: Srinivas Katar, Hao Zhu, Lawrence Winston Yonge, III, Manjunath Anandarama Krishnam

Patent number: 8867594Abstract: A non-liner device (NLD) between powerline communication (PLC) devices can introduce significant distortion into the channel being utilized by the PLC devices. This distortion can create errors and corrupt data transmitted by the PLC devices. When trying to mitigate the effects of the distortion introduced by NLDs, PLC devices conform their mitigating actions to effectively satisfy a limit(s) set by a regulation and/or a standard. A PLC device implemented in accordance with this disclosure can mitigate the distortion effects with deference to regulatory/standard limits without knowledge of what types of NLDs and how many NLDs are coupled to the power line. A PLC device can use different techniques to infer the presence of an NLD in a PLC network. A PLC device can infer the presence of the NLD using a passive technique or one or more active techniques.Type: GrantFiled: March 15, 2013Date of Patent: October 21, 2014Assignee: Qualcomm IncorporatedInventors: Faisal Mahmood Shad, Lawrence Winston Yonge, III

Patent number: 8862069Abstract: A method includes determining a signal strength value for a first received signal received from a first station in a first network. The first received signal is received in the first network through a shared communication medium that is shared with a second network. The method includes receiving an indicator of a signal strength value determined for a second received signal from a second station in the second network. Based on the signal strength value for the first received signal and based on the indicator of the signal strength value determined for the second received signal, a detection threshold is selected such that, in response to a third received signal having a signal strength in excess of the detection threshold, the third received signal is processed according to a protocol of the first network and is not processed according to a protocol of the second network.Type: GrantFiled: June 20, 2013Date of Patent: October 14, 2014Assignee: QUALCOMM IncorporatedInventors: Lawrence Winston Yonge, III, Srinivas Katar, Manjunath Anandarama Krishnam
