1G:开创“移动电话”1G,第一代移动通讯技术,以模拟技术为基础的蜂窝无线电话系统,如现在已经淘汰的模拟移动网。1G无线系统在设计上只能传输语音流量,并受到网络容量的限制。AMPS(高级移动电话系统,由美国开发的最早的蜂窝电话系统标准)为1G网络的典型代表。第一代移动通信技术(1G)是指最初的模拟、仅限语音的蜂窝电话标准,制定于上世纪80年代。 1G: Startup “Mobile Phone” 1G, the first generation of mobile communication technology, based on analog technology, cellular radiotelephone systems such as analog mobile networks that are now phased out. 1G wireless systems are designed to deliver only voice traffic and are limited by network capacity. AMPS (Advanced Mobile Phone System, the earliest cellular phone system standard developed by the United States) is a typical representative of a 1G network. The first generation of mobile technology (1G) was originally the analog, voice-only cellular phone standard, set in the 1980s.
