1. In a frequency band, a method of intelligent frequency hopping, comprising:
- sampling a plurality of channels in the frequency band;
identifying each channel in the plurality of channels as a good channel or a bad channel as a function of a predetermined factor; and
assigning the good channels to a good window and the bad channels to a bad window.

Abstract
The invention generally provides a method of intelligent frequency hopping such as in Bluetooth and Home RF networks. The method (100) includes the acts of sampling a plurality of channels in a frequency band and identifying each channel as a good channels or a bad channel (110), determining the size of a good window and the size of a bad window (120), and assigning a plurality of good channels to a good window (130) and a plurality of bad channels to a bad window (140). Accordingly, the method increases the reliability and throughput of wireless networks.

19. A method of intelligent frequency hopping, comprising:
-
sampling channels of a frequency band;
identifying each channel in the frequency band as a good channel or a bad channel;
determining a ratio of the good channels to the bad channels (the ratio);
assigning a first size to a good window, and a second size to a bad window, such that the ratio of the size of the good window to the size of the bad window is the same as the ratio; and
assigning a plurality of the good channels to the good window and a plurality of the bad channels to the bad window.
