1 GPRS 的发展历史GPRS 发展的历史,实际上就是移动通信发展的历史。移动通信赖以生存的无线电频率是一种宝贵的资源,而且频谱资源是有限的。随着移动通信的飞速发展,移动用户急剧增加,有限的资源被“无限”地利用,矛盾越来越尖锐。解决这一对矛盾就是移动通信技术的发展史,也就是说移动通信技术的发展过程就是不断
1 GPRS development history GPRS development history, in fact, is the history of the development of mobile communications. The radio frequency on which mobile communications depend is a valuable resource, and spectrum resources are limited. With the rapid development of mobile communications, the number of mobile users has increased dramatically. Limited resources have been used “infinity” and conflicts have become increasingly acute. To solve this conflict is the history of mobile communications technology, that is to say the development of mobile communications technology is constantly
