汉英对照/5G比当前的蜂窝网络使用更高频率的无线电波

5G比当前的蜂窝网络使用更高频率的无线电波，这可以部分提高速度。 但是，高频无线电波的范围比以前的手机发射塔使用的频率短，因此所需的小区更小。 因此，为了确保广泛的服务范围，5G网络可以在低，中和高三个频段上运行。

5G uses higher frequency radio waves than current cellular networks, which can partially increase speed. However, the range of high-frequency radio waves is shorter than the frequency used by previous cell phone towers, so the required cells are smaller. Therefore, in order to ensure a wide range of services, 5G networks can operate on three frequency bands, low, medium and high.
