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随着传达距离增大而逐步衰减的实际,因此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烦扰很小。

(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 decreases with the increase of the transmission distance, so there is little disturbance to each other when the same channel is reused in two areas separated by a certain distance in space.)
