  • Patent number: 7869529
    Abstract: A system for detection and avoidance of victim services in ultra-wideband (UWB) systems is provided. A detect and avoid module may calculate power averages of Orthogonal Frequency Division Multiplexing tones. The power of tones may be measured and compared with power averages of corresponding tones. If a measured tone power exceeds an average power of a corresponding tone by a dynamic threshold, the tone may be identified as associated with an interferer. The threshold may be inversely related to the gain level of an automatic gain control module. The UWB subsystem may be configured with known bands of victim services of other radio frequency systems, and a tone identified as associated with an interferer that is within a known victim service band may be identified as a victim service. The UWB subsystem may attenuate or otherwise suppress transmission within the victim service band to avoid interfering with the victim service.

  • Publication number: 20070291636
    Abstract: A system, method, and computer-readable medium for detection and avoidance of victim services in ultra-wideband systems is provided. A detect and avoid module may calculate power averages of OFDM tones. The power of tones may then be measured and compared with power averages of corresponding tones. If a measured tone power exceeds an average power of a corresponding tone by a dynamic threshold, the tone may be identified as associated with an interferer. The threshold may be inversely related to the gain level of an automatic gain control module. The ultra-wideband subsystem may be configured with known bands of victim services of other RF systems, and a tone identified as associated with an interferer that is within a known victim service band may be identified as a victim service. The UWB subsystem may attenuate or otherwise suppress transmission within the victim service band to avoid interfering with the victim service.

  • Patent number: 7290049
    Abstract: A method and system to provide management information of network devices by mapping between SNMP MIB module schema and Common Information Model (CIM) schema. MIB modules are tree-structured lists of objects for describing SNMP network device information, whereas CIM schema employs user-intuitive, object-oriented classes to model such information. A mapping process enumerates the MIB objects and then maps the objects into CIM Managed Object Format (MOF) classes using defined mapping tables. A correlation mechanism is further provided to efficiently determine in real time which MIBs (or portions thereof) and corresponding CIM classes a network device supports.
