| 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. Through such information exchange, the other party can independently control and optimize the transmission power level for each used segment, e.g., to a minimum transmission power level at which no error has occurred.

First Claim:
Show all 23 claims |
What is claimed is:
1. A method for performing frequency hopping communication with another party over an available spectrum of frequencies, the spectrum being arranged into a plurality of segments, each segment comprising a subset of the available spectrum including multiple possible hopping frequencies, the method comprising the steps of:
- (a) receiving data over a used segment from the plurality of segments and signal strength data indicating a current reception power level for the used segment at the receiving party;
- (b) analyzing the received data to determine an occurrence or non-occurrence of an error over the used segment; and
- (c) notifying the other party to modify the current transmission power level of the used segment according to the occurrence or non-occurrence of reception errors.
