    Abstract: Systems and methods are described for detecting interference at an access node. A rate at which packets are unsuccessful received at a wireless device may be monitored, wherein the wireless device is in communication with a cell of an access node. The access node may retransmit one or more unsuccessfully received packets to the wireless device. A retransmission metric for retransmission attempts to the wireless device from the access node may be monitored. And it may be determined that communication between the cell of the access node and the wireless device is experiencing interference from a neighboring cell when the monitored rate and monitored retransmission metric meet the interference criteria.

    Abstract: This disclosure relates to systems, methods, and apparatus for limiting or throttling an activity of an accessory device communicatively coupled to a computing device. The activity of the accessory device is limited or throttled in order to reduce electromagnetic interference and improve signal quality of a wireless communication in which the computing device is participating. In some embodiments, a decision to throttle can be based on battery charge level of the computing device. For example, in some embodiments, the accessory device is an accessory battery charger configured to provide power to the computing device when a power outlet is not immediately available. If the signal quality of a phone call from the computing device is diminished or the user is in an area of low signal coverage, the accessory battery charger can be limited or throttled in order to prevent interference between the accessory battery charger and computing device.

  • Patent number: 9484979
    Abstract: A wireless transceiver decodes a receive signal to extract data contained in the receive signal. A processing block contained in the wireless transceiver then initiates a power-ON of the transmit radio portions of the transceiver prior to initiating a power-OFF of the receive radio portions. The technique enables the transceiver to meet timing requirements when operating in environments that require an acknowledgement to be sent in response to receipt of data.

  • Patent number: 9467247
    Abstract: A signal is detected and an unwanted jamming signal is removed from the detected signal. Respective first, second and third correlations between a received signal and signals at first, second and third frequencies are determined over a plurality of taps. The second frequency is higher than the first frequency and lower than the third frequency, and is equally spaced from the first and third frequencies. The second frequency is adapted to a frequency of the received signal such that peaks in the first and third correlations after corresponding adaptation of the first and third frequencies have substantially equal magnitudes. A difference is determined between non-peak magnitudes of the first and third correlations; and at least one of the correlations is compensated for the effects of the jamming signal, based on said difference.

    Abstract: A user may access a website via a mobile channel using a mobile device. As the user is logged into the website, the user may call or otherwise contact a representative via another communications channel with the mobile device or another user device, such as a phone or a user computing device or another mobile device. An emulator engine may determine the type of mobile device that the user is using to access the website via the mobile channel. An emulator for the mobile device that has been determined may be retrieved from an emulator library and provided to the representative computing device. The representative may view the same user interface on the representative computing device that the user sees on the mobile device.

  • Patent number: 9379841
    Abstract: Technologies related to mobile device prevention of contactless card attacks are generally described. In some examples, a mobile computing device may monitor for electromagnetic signals at frequencies used for short range communications with contactless cards. Detection of such electromagnetic signals by the mobile computing device may indicate an attack attempt on a proximal contactless card. In response to detection of such electromagnetic signals, the mobile computing device may automatically generate a disruption signal effective to disrupt communications between contactless card readers and any proximal contactless cards, to thereby foil the attack before sensitive contactless card data is stolen.

  • Patent number: 9351307
    Abstract: Reported CSI may not reflect non-cancelable CRS interference received from an interfering cell, such as when the CSI is computed when CRS interference is not received. To address the issue, a user equipment (UE) may determine an interference cancelation/suppression efficiency (CSE) associated with canceling/suppressing interference from interfering cells. In addition, based on the determined CSE, a UE may compute CSI such that the CSI reflects the true cancelation efficiency of the UE with respect to interfering cell signals. When computing the CSI based on the determined CSE, the UE may report that the CSI is worse than it is to reflect the UE's true cancelation efficiency with respect to the interfering cell signals.
