But if an upgrade is required, the network speed should be fast enough to support a new version to be uploaded from ground control center to space.

但是如果需要升级， 网络速度应该足够快以支持新版本从地面控制中心上传到太空。

The faster network speed also allows more complex experiments to be conducted in China's space labs, Bo added, something the previous Tiangong-1 and -2 could not realize due to limited bandwidth.

薄补充说，更快的网络速度也允许在中国的空间实验室进行更复杂的实验，这是以前的天宫一号和天宫二号由于带宽有限而无法实现的。
