The analysis showns that MRC decreases the outage probability and increases the system coverage, compared with the soft handoff in a CDMA system. 研究结果表明它比码分多址中的软切换中所采用的选择式宏分集能够带来更低的中断率，从而提高系统的覆盖。
The handover zones need to be minimized to well-defined small areas, or the soft HO can cannibalize the capacity in the network. 切换区域需要很好的定义并尽量小，否则软切换将占用网络的容量。
