  • Patent number: 6115407
    Abstract: The present invention is an apparatus and method thereof for performing frequency hopping (FH) communication with another party over an available spectrum of frequencies. The spectrum is arranged into a plurality of segments, with each segment corresponding to a subset of the frequencies, preferably a contiguous subset of the frequencies. The FH communication apparatus includes a communication device for communicating with another party. The communication device receives data over a sequence of hopping frequencies from the other party, with each of the hopping frequencies being part of a used segment from the plurality of segments. A storage device stores an error value for each used segment. A processing unit identifies a reception error in the received data and an erred segment in which the reception error occurred. The processing unit modifies the error value associated with the erred segment accordingly.

  • Patent number: 6115408
    Abstract: The present invention is an apparatus and method thereof for performing frequency hopping communication with another party over a subset of hopping frequencies from available frequencies. The spectrum is arranged into a plurality of segments, with each segment corresponding to a subset of the spectrum of frequencies, preferably a contiguous subset of the spectrum. The apparatus includes a communication device for communicating with another party. The communication device receives data over a used segment from a plurality of the segments and signal strength data indicating a current reception power level for the hopping frequency from the other party. A processing unit analyzes the received data to determine an occurrence or non-occurrence of an error over the used segment and notifies the other party to modify the current transmission power level for that used segment according to the occurrence or non-occurrence of an error, via said communication means.
