  • Patent number: 9065908
    Abstract: A mobile device may communicate with a location server during location based services (LBS) operations using a secure identifier. The secure identifier abstracts identification information of the mobile device and/or identification information of a user of the mobile device in instances that the mobile device and/or user identification information are deemed protectable from the location server. The location server may be operable to store location data corresponding to the mobile device and/or the user in a location reference database based on the secure identifier. The secure identifier may comprise a unique value, which may be randomly generated. The secure identifier may also be generated based on the mobile device and/or user identification information, by applying, for example, encryption algorithms to the mobile device and/or user identification information.

  • Publication number: 20150147987
    Abstract: The present disclosure is directed to a system and method for performing digital up-conversion of a signal to a desired RF carrier frequency. The system and method efficiently perform digital up-conversion of the signal, in one example, by controlling a sample clock that is used by a DAC to sample and convert the up-converted signal from the digital domain to the analog domain to have a frequency that is four or eight times the desired RF carrier frequency. By controlling the sample clock of the DAC to have a frequency that is four or eight times the desired RF carrier frequency, the system and method can be implemented using currently available IC process geometries such that the implementation consumes much less area and/or power than an analog up-converter configured to have equivalent up-conversion functionality.

  • Publication number: 20150126158
    Abstract: A transmitting communication device may iteratively adjust its transmit power, and may estimate, based on iterative transmit power adjustment, relative location of a receiving communication device. The transmit power may be initialized to a maximum value, and the transmit power may be iteratively reduced until connectivity with the receiving communication device is lost. The loss of connectivity may be determined based on reception of responses to ping messages transmitted by the transmitting communication device. The transmitting communication device may authenticate the receiving communication device and/or a user of the receiving communication device. The authentication may comprises utilizing transmit power adjustment and/or relative location estimation therefrom to ensure that a separation between the devices does not exceed a maximum value.

  • Publication number: 20150095635
    Abstract: A method and system that allows a host system application to securely communicate with a legacy device is provided. A redirector software module receives data that is destined for a host system serial COM port. Data is secured and re-directed to a legacy device via a network port instead of the serial COM port. Conversely, data destined for the host system is provided to a device server via a server COM port by the legacy serial device. The data can be encrypted and sent to the host system via the network. The redirector software module decrypts the encrypted data and presents it to the consumer application as if the data had arrived via the local COM port.

  • Patent number: 8958821
    Abstract: A multi-radio mobile device comprises a plurality of different radios. When a location update occurs, the multi-radio mobile device, at a specific location, acquires location-based radio information from a remote location server. The multi-radio mobile device selects a radio for use in the specific location based on the acquired location-based radio information comprising available radios in the specific location and radio weights. The radio is selected from the available radios based on the radio weights in the specific location. Transmissions of a desired service are received in the specific location utilizing the selected radio. Location-based radio measurements reports to the remote location server are generated utilizing signal strength measurements for the received signals. Radio quality information of the available radios is calculated by the location server utilizing location-based radio measurement reports from associated users.

  • Publication number: 20140379886
    Abstract: A broadband gateway, which enables communication with a plurality of devices, handles at least one physical layer connection to at least one corresponding network access service provider. Before allowing the devices to access content from the service provider, the broadband gateway may identify a device power profile for each of the devices, and a network power profile for the content to select a corresponding content delivery mechanism to optimize power consumption. The content may be communicated to the devices utilizing the corresponding selected content delivery mechanism. Depending on configuration, content transcoding may be performed at the broadband gateway and/or at the devices. The content may be burst downloaded and stored in a local storage to be consumed by the devices thereafter. Upon completion of download, the broadband gateway may shut down receiving components to save resources and power. The receiving components may be tuned on to receive additional content when needed.
