摘　　要：为了明确EVDO RevA系统前向链路和反向链路速率关系,通过建立两个全向EVDO RevA站点模型,利用前反向链路预算进行计算,分析了前向和反向速率连续覆盖间的关系,提出不同无线环境下前反向速率与站点距离的关系,指出在反向速率覆盖边缘前向DRC速率可以达到76.8 kb/s,并通过网络仿真预测了标准蜂窝结构下的前反向速率关系。For making clear the relationship between the forward and reverse link data rates, the forward and reverse link budget is used, and data rate for continuous coverage in reverse and forward link is analyzed through establishing two omni-antenna base stations of EVDO RevA. This paper presents the relationship between data rate and sites distance, points out that the forward link data rate could reach upto 76.8 kb/s at the reverse link coverage border. Also the relationship between the forward and reverse link data rates in standard cellular topology is predicted through network simulations.
