无线网络最成功的使用是蜂窝电话系统。蜂窝系统使用发射出去的信号效率跟着传达距离增大而逐步衰减的实际,因而同一频道在空间上离隔一定距离的两个地段内重复使用时相互间的搅扰很小。

(The most successful use of wireless networks is in cellular telephone systems. The cellular system uses the fact that the efficiency of the transmitted signal gradually attenuates with the increase of the transmission distance, so the interference between the same channel is very small when it is reused in two areas separated by a certain distance in space.)
