  • Patent number: 7995687
    Abstract: Aspects of a method and system for fast and reliable channel classification in Bluetooth networks to detect and avoid channel interferers may include one or more processors that may enable performance of signal strength measurements on received Bluetooth signals at a current selected frequency. At least one data packet received via the Bluetooth signals may be processed to determine the presence of bit errors. The processor(s) may enable characterization of the Bluetooth signals at the current selected frequency based on the signal strength measurements and/or the processing of the data packets. The current selected frequency may be selected during adaptive frequency hopping based on the characterization.

  • Patent number: 7333514
    Abstract: Synchronous and asynchronous data traffic over multipoint ad-hoc telecommunication networks is scheduled in frames, and bandwidth in such networks is allocated based on packet type and traffic type by a scheduler that points to frame descriptors, or data structures, that define where data is located, what packet type to use for the transmission, etc. The scheduling of reception is implicit, viz., there is always a transmit/receive descriptor pair. The same scheduler can schedule traffic in interconnected networks in which there is a participant, even if the networks are unsynchronized to one another, and the scheduler can schedule connection-setup actions, such as page and inquiry. The scheduler can also schedule non-actions, or inactivity, such as “no operation” and “sleep”.
