  • Patent number: 8374618
    Abstract: A system for managing the operation of a plurality of radio modules integrated within the same wireless communication device. A control strategy may be employed to manage both more predictable and more spontaneous wireless communication mediums, wherein a local controller may be employed in a radio module utilizing an unscheduled wireless medium, like WLAN, for determining whether adequate time has been allocated to complete a transaction. If the transaction cannot be completed in the allowed time, it may be delayed until adequate time exists, and the delay may be reported so that the time may be reallocated to other radio modules. The radio module may then enter a power-saving mode until the transaction can be completed.

  • Patent number: 8005465
    Abstract: A system for conveying wireless information between an advertising device (advertiser) and another wireless communication device (receiving device). The advertiser's broadcast signal (advertisement) may inform the receiving device that information is available from the advertiser without the requirement of establishing a formal network connection. This information may be then be conveyed, by request, to the receiving device. Further, the advertising device may, in some instances, continue to broadcast to other receiving devices even though it is already engaged in a formal network connection with a receiving device.

  • Patent number: 7949364
    Abstract: A system for managing the operation of a plurality of radio modems contained within the same WCD. One or more of the plurality of radio modems may be a dual-mode radio modem enabled to communicate using at least two separate radio protocols concurrently. The operation of the one or more dual-mode modems may be managed by resources encompassed in a radio modem interface coupled to, or integrated within, the dual-mode radio modem. These management resources may receive information from the operating system level of the WCD and from the at least two radio modem stacks utilizing the resources of the dual mode radio modem in order to coordinate the operation of the at least two radio protocols concurrently active in the modem.

  • Patent number: 7848741
    Abstract: One or more electromagnetic energy measurements are generated. Each of these measurements corresponds to an available communications bandwidth for a communications device and indicates a frequency of a radio frequency (RF) signal source. From these measurement(s), one or more interference sources are identified. These measurements may include a series of electromagnetic energy measurements over a predetermined time period. An interference source may be identified when each measurement in the series of electromagnetic energy measurements indicates an RF energy source at the same frequency. Each of these measurements may be stored. In addition, statistics regarding these measurements may be generated.

  • Patent number: 7809361
    Abstract: A security enhancing system for creating temporary identification information used to mask actual identification in a wireless communication device. The temporary identification information conforms to a standard usable by at least one wireless communication medium, and may be used by other devices in communicating with the wireless communication device, however, only other devices possessing secret address component information may determine the actual identity of the masked wireless communication device. The temporary identification information may further be recompiled when a threshold condition is satisfied.

  • Patent number: 7809012
    Abstract: A system for optimizing the operation of a plurality of radio modules incorporated within a wireless communication device (WCD) connected as a slave on a low-power wireless network, wherein a low-power device is acting as the master of the wireless network. The timing of communication between master and slave may be established by the master, and as a result, the WCD may utilize a control strategy to allow substantially concurrent active communication in one or more of the plurality of radio modules while still operating under the parameters set forth by the low-power master device.

  • Patent number: 7760671
    Abstract: A method for use by a device communicating according to a short-range wireless connectivity protocol in attempting to establish a connection to another device using an enhanced inquiry and/or paging procedure as part of the connection procedure, the method including a step in which the device transmits a first packet for establishing a connection to the other device, and the other device responds with one or more response packets whose content depends on whether the other device is configured to perform the enhanced procedure. In some embodiments, the first packet is an identifier packet including extension data indicating via a predetermined bit pattern that the device is itself configured to perform the enhanced procedure.

  • Patent number: 7680520
    Abstract: The present invention relates to systems and methods for a implementing an optimized power conservation communication protocol, wherein the communication link is flexible and the power consumption characteristics are optimized. One facet of the system's flexibility relates to the system's ability to negotiate device control roles associated with a polling communication link. Also, once the device control roles are in place and the communication link is established, the system selectively implements a number of polling protocols for a multitude of applications that need a low power consumption. In some embodiments the system maintains a communication link with a reduced frequency polling protocol. This type of communication link maintains efficient power consumption characteristics, as well as, connection times that are faster than establishing a communication link between disconnected devices.

  • Patent number: 7664532
    Abstract: A system for managing the simultaneous operation of a plurality of radio modems in a single wireless communication device (WCD). The multiradio control may be integrated into the WCD as a subsystem responsible for scheduling wireless communications by temporarily enabling or disabling the plurality of radio modems within the device. The multiradio control system may comprise a multiradio controller (MRC) and a plurality dedicated radio interfaces. The radio interfaces are dedicated to quickly conveying delay sensitive information to and from the radio modems. The modems may further include control features that take information from the MRC as an input in determining the priority of messages to be sent out to a receiving device.
