Let's start off with the simplest, RF wristbands, that receive a radio frequency communicating the precise timing and colors for each band.

让我们从最简单射频开始，它接收一个无线电频率，传达每个精确时间和颜色。

They did not file flight plans, radio ahead or register their frequencies.

他们并没有提交飞行计划，无线电波或频率。

This depends on the precise radio frequency of the 21-cm wavelength, or 1420 megacycles per second.

这取决于 21 厘米波长或每秒 1420 兆周精确无线电频率。

I can just amplify the signal to a radio headset frequency.

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.

该部门将确保新发射卫星不会使用会干扰现有卫星无线电频率，并计划何时发射这种新卫星。

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 网络建立本相对较低，因为它们能够在该国无线电频谱现有频率上推出。

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到我们银河系中心并用对无线电频率敏感眼睛观看场景，那么从团队制作模拟中可以明显看出这一点。
