Considering about the different versions of UMB protocol, the performance of the first edition is the worst.
而在版本方面，U MB第一版协议性能最次，第二版与第三版性能相当。
In the image of the establishment's existing pavilions, the UMB was completed in the shape of an open "U", enclosing a garden.
基于原有建筑的形象，母婴中心被塑造成u型，围合成一个花园。
And the capacity of the UMB systems has been greatly improved by using the multiple antenna technology, like the Closed-loop MIMO.
还有闭环MIMO等多天线技术的使用，使得umb系统的系统容量有了极大的提升。
