Abstract
An apparatus and method that optimizes the data rate for forward link data transmissions in a spread-spectrum communications systemis provided. The spread-spectrum communications systemcomprises a wireless infrastructure, at least one wireless mobile receiving device, and an radio frequency (RF) forward linkbetween the wireless infrastructureand the wireless mobile receiving device. The data rate of the RF forward linkis optimized in the wireless infrastructureby estimating or measuring the bottleneck link speed of the data transmission and adjusting the data rate for the RE forward linkaccording to several embodiments of a data rate optimization algorithm. The algorithm creates an optimum range for the data rate of the RF wireless linkwhich maximizes system capacity and reduces transmission delays to the wireless mobile receiving device
