自从70年代第一代数字无线寻呼机(BB机)发明以来,随着微电子技术的发展,机内元件的集成化程度越来越高,功能也越来越强.数字无线寻呼机已进入第二代. 我们对国外生产的BB机(如MOTOROLA,NEC等进行了长达一年多的分析比较,结合我国的国情,建成一套从模拟无线寻呼发射台到寻呼机传真器的实用系统,经过近两年的努力,开发出第一代及第二代数字无线寻呼机,第二代多功能文字型显示(中、英、日、俄 Since the first generation of digital radio pagers (BB machines) was invented in the 1970s, with the development of microelectronic technology, the integration of the components in the machines has become more and more advanced and the functions become more and more powerful. The digital radio pagers have entered the second On the basis of the actual conditions of our country, we have built a set of practical systems for the BB machines (such as MOTOROLA, NEC) that have been manufactured abroad for more than a year and have completed a set of practical systems ranging from analog radio paging transmitters to pager facsimiles. In the past two years, we have developed the first and second generation digital radio pagers, the second generation multi-function text displays (Chinese, English, Japanese and Russian
