无线电移动通信技术和业务的开展虽仅十余年历史,却已迅速获得极为可观的发展,并在通信领域中占领不小的市场,受到用户的普遍欢迎。预计在未来不远的时期内,移动通信技术必将巩固原有基础和更新换代,越来越多的人们乐意使用移动通信,取得更大的通信便利。追溯无线电移动通信的发展进程:最初是无线电寻呼(radio-paging),单方向传送信号和消息;其次为无绳电话(cordless telephone),在一定的小地区范围内互通电话;再扩充至蜂窝分区网(cellular radio),在一个较大地区内实现移动通信,并能进入公用通信网。这三种移动通信都可能继续发展和改进。展望90年
Although mobile radiocommunications technologies and services have only been developed for more than ten years, they have rapidly gained remarkable progress and have gained a large market share in the field of communications. They are generally welcomed by users. It is expected that in the near future, mobile communication technology will surely consolidate the original foundation and upgrade, and more and more people are willing to use mobile communications for greater communication convenience. Tracing back to the evolution of radio-mobile communications: Radio-paging was originally a one-way transmission of signals and messages; followed by cordless telephones, which interworked within a certain small area; and then expanded to cellular divisions Cellular radio, mobile communications in a large area, and access to public communications networks. All three types of mobile communications are likely to continue to evolve and improve. Looking 90 years
