Abstract
A wireless data communications network utilizes a frequency synthesizer to achieve a systematic frequency hopping arrangement wherein frequency is incremented by two times the channel spacing from lowest frequency to highest frequency. When adjusting the frequency from highest frequency to lowest frequency a one times the channel spacing frequency hop is utilized for the first and half and last hop and two times the frequency spacing is utilized otherwise. In this manner, alternating frequencies are selected so that the same frequency is only utilized once during any complete cycle and the size of frequency transitions is held to a minimum allowing a narrow bandwidth filter and inexpensive implementation of the phase locked loop portion of the synthesizer.
