  • Publication number: 20090274315
    Abstract: Techniques to reduce distortion in acoustic signals in mobile computing devices are described. For example, a mobile computing device may comprise a speaker operative to receive a first signal and output a second signal. The mobile computing device may further comprise a first microphone operative to receive the second signal and a second microphone operative to receive a third signal. An echo canceller may be coupled to the first microphone and the second microphone and may be operative to compare the second signal and the third signal and reduce distortion in the third signal based on the comparison. Other embodiments are described and claimed.

  • Publication number: 20090258607
    Abstract: Techniques for enhanced co-existence for co-located radios are described. A mobile computing device may comprise a first radio module operative to communicate wirelessly across a first link using a first set of communications channels, a second radio module operative to communicate wirelessly across a second link using a second set of communications channels, and a coordination module operative to receive information regarding operation of the first and second radio modules, and modify a communications parameter for the first or second radio module based on the received information. Other embodiments are disclosed and claimed.

  • Publication number: 20090247239
    Abstract: Techniques to characterize and reduce acoustic echo are described. For example, a mobile computing device may comprise an audio characterization module to send a first signal to a first component and receive a second signal from a second component. The first signal may be a deterministic audio training sequence and the second signal may be a recovered audio training sequence. The audio characterization module compares the first signal and the second signal to determine an audio echo path. Other embodiments are described and claimed.

  • Publication number: 20090170447
    Abstract: A shared antenna architecture for multiple co-located radio modules is disclosed. For example, an apparatus may include an antenna, a first transceiver to communicate wirelessly across a first link, a second transceiver to communicate wirelessly across a second link, and a shared antenna structure communicatively coupled to the first transceiver, the second transceiver and the antenna. The shared antenna structure may comprise a combiner and at least one switch arranged to allow the first transceiver and the second transceiver to share the antenna for simultaneous operations or mutually-exclusive operations. Other embodiments are disclosed and claimed.

  • Publication number: 20080143616
    Abstract: Various embodiments of an internal antenna and motherboard architecture are described. In one embodiment, a wireless device may include a housing enclosing a first motherboard and a second motherboard. The ground plane of the first motherboard may be coupled to the ground plane of the second motherboard within the housing. The first motherboard and the second motherboard may act as an internal antenna system for the wireless device. Other embodiments are described and claimed.

  • Publication number: 20080102835
    Abstract: Motion-based handoff control techniques are disclosed. For example, an apparatus may include a signal strength determination module, a motion determination module, and a handoff controller. The signal strength determination module generates signal strength information corresponding to the strength of a wireless signal received from a first wireless link. From this information, the motion determination module determines a motion characteristic of the apparatus. Based on the motion characteristic, the handoff controller performs handoff operations for a second wireless link. In this manner, handoff operations may be tailored to the operational characteristics of the apparatus. For instance, certain handoff operations may be halted when the motion characteristic indicates the apparatus having a substantially stationary position. Other embodiments are described and claimed.

  • Publication number: 20080102885
    Abstract: Techniques involving the coordination of wireless activities are disclosed. For example, an apparatus may include two or more transceivers. These transceivers may include a first transceiver to communicate wirelessly across cellular links, and a second transceiver to communicate wirelessly across wireless data networking links. The apparatus may also include controllers, each controlling wireless communications of a corresponding transceiver. Information may be exchanged with each other regarding operation of the transceivers. Through the exchange of such information, activity (e.g., transmission and reception of wireless signals) may be coordinated among the transceivers.

  • Publication number: 20070249315
    Abstract: During a telephony session, a determination is made on a mobile computing device that one or more designated conditions exist by which radio interference generated from the mobile computing device is to be reduced. In response, a power state of a set of one or more components of the mobile computing device is lowered. This reduces radio interference from those components. The set of components are ancillary to the mobile computing device's ability to maintain the telephony session, so that the telephony session is not affected by the reduction of power to the components.
