国内现有的无线移动通信单工传呼系统(Radio-Paging System),其终端接收机俗称BP机,解决了有线固定通信不能解决的紧急情况下的通信,而得到较广泛的应用,它是无线电、通信与计算机技术相结合的高科技产物。但其工作方式还只局限于数码或汉字显示的“电报型”传呼机,使用不够方便。对传递稍复杂一点的信息,则必须经复机联络才能达到彻底明确,这甚至是很误事的;若在无电话机可供联络时,则使这种BP机持有者陷于焦急而无奈。 西安某电子公司于1994年研制成功了语音传呼通信系统,1995年相继在吉林通化、山西运城等地建台,今年又在西安市建立大功率语音传呼台,受到
The existing domestic wireless mobile communication simplex paging system (Radio-Paging System), the terminal receiver commonly known as BP machine, solves the wired fixed communication can not solve the emergency communication, and get a wider range of applications, it is radio , A combination of communication and computer technology, high-tech products. However, its mode of operation is limited to “telegraph” pagers displayed in digital or Chinese characters, which are not easy to use. To pass a little more complicated information, it is necessary to go through the complex machine contact to be completely clear, which is even a very wrong thing; if there is no phone available for contact, then the BP machine holder in anxiety and frustration. An electronic company in Xi’an successfully developed a voice paging communication system in 1994. In 1995, it built the stations in Tonghua, Jilin and Yuncheng, Shanxi, and set up high-power voice paging stations in Xi’an this year.
