The department will make sure that newly launched satellites don't use radio frequencies that would interfere with existing satellites, and schedule when such new satellites can be launched.

该部门将确保新射的卫星不会使用会干扰现有卫星的无频率，并计划何时射这种新卫星。

In the U.K. for example, 3G and 4G networks were relatively cheap to set up because they were able to roll out on existing frequencies, on the country’s radio spectrum.

例如，在英国，3G 和 4G 网络的建立成本相对较低，因为它们能够在该国无频谱的现有频率上推。

This is very apparent from the simulations the team has produced of what you would see if you could somehow take yourself to the centre of our galaxy and view the scene with eyes sensitive at radio frequencies.

如果你能以某种方式将自己带到我们银河系的中心并用对无频率敏感的眼睛观看场景，那么从团队制作的模拟中可以明显看这一点。
