To accommodate more users with limited spectrum, the radius of new cellular will be much smaller, the factor of spectrum reuse will be more tight.

为了在有限频谱范围内满足更多的用户需要，通信系统的蜂窝半径越来越小，频率复用密度越来越高。

Andrea Goldsmith: There's not enough spectrum to assign every phone in the world its own dedicated channel so we have to reuse the channels and that causes interference between users.

安德里亚·戈德史密斯：由于频谱资源有限，我们很难让每个用户享有特定的频段，只能不断地将它们回收利用，导致用户之间出现通信干扰。

So we see a virtuous complementarity: more, better spectrum will boost spectrum reuse efficiencies.

In other words, spectrum reuse and more spectrum are not either-or alternatives but are mutually helpful and reinforcing.
