摘要：A wireless communications system that has variable power levels incommunications frames may be provided. The wireless communication system mayinclude a plurality of cells that include transmitters for providing communications
services to a geographic area. Each cell may be assigned a channel selected from alimited number of available channels. Communications frames may be transmitted in thecells using a plurality of data rates. Each communications frame may include a portionthat is to be transmitted at one of the data rates. The power level used for transmittingthat portion of a communications frame may be selected (e.g., lowered) to limit at whatdistances that portion may be properly received. Locations of cells in the geographic areamay be partly determined based on the power levels.
