第一阶段是模拟蜂窝移动通讯网。时间是本世纪七十年代中期至八十年代中期。1978年，MG贝尔实验室研制成功抢先移动电话系统（AMPS），建成了蜂窝状移动通讯系统。而其它工业化G家也相继开发布蜂窝式移动通讯网。

(The first stage is to simulate the cellular mobile communication network. The time is from the mid-1970s to the mid-1980s. In 1978, Bell Labs in the United States successfully developed the Advanced Mobile Phone System (AMPS) and built a cellular mobile communication system. And other industrialized countries have also developed and released cellular mobile communication networks.)
