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。
In order to clarify the relationship between the forward link and the reverse link rate of EVDO RevA system, two omnidirectional EVDO RevA site models were set up and the forward link budget was used to calculate the relationship between forward and reverse rate continuous coverage The relationship between the forward reverse rate and the station distance in different wireless environments is proposed. The DRC rate in the forward direction of the reverse rate coverage edge can reach 76.8 kb / s, and the forward reverse rate under the standard cellular structure is predicted by the network simulation relationship.
