RRM testing is designed to use limited RF resources as efficiently as possible and to help avoid co-channel interference.The 3GPP specification for RRM testing defines five different pairs of angles with relative angular differences between base station signals of 30°,60°,90°,120°and 150°.The R&S ATS1800M meets this requirement with only three additional reflectors.The original R&S ATS1800C can also be fitted with this side chamber expansion option,which can be restored to its original state.

RRM测试旨在尽可能高效地使用有限的射频资源，并帮助避免同信道干扰。用于RRM测试的3GPP规范定义了五对不同的角度，基站信号之间的相对角度差为30°、60°、90°、120°和150°。R&S ATS1800M仅增加了三个附加反射面即可满足这一要求。原版R&S ATS1800C也可以加装这一边室扩展选项，加装后还可以恢复原状。
