随着科技的进步,整个社会向着信息化发展。信息化社会首先离不开通信,通信已成为现代社会的支柱之一。通信可分为有线通信与无线通信。通常,有线通信适合于固定通信,无线通信适合于移动通信。然而现代的通信要求有线与无线通信有机地联接起来,使人们能在移动中随时得到信息保持通信联络。达到这一目的通信系统当然有许多,其中的佼佼者有:蜂房移动电话(俗称“大哥大”),公用无绳电话(CT2等),无线寻呼(BB机)。前两者可以实现双向通话,是较为理想的通信工具,但这类系统所需费用较昂贵。无线寻呼系统具有系统结构简单、组网快、价格便宜、使用灵活方便等特点,故发展最为迅速。无线寻呼是一种单向传送寻
With the progress of science and technology, the entire society is developing toward informationization. First of all, information-based society can not do without communication. Communication has become one of the pillars of modern society. Communication can be divided into wired and wireless communication. In general, wired communication is suitable for fixed communication and wireless communication is suitable for mobile communication. However, modern communication requires wired and wireless communication to be organically connected, so that people can always get the information in mobile communication. Of course, there are many communication systems to achieve this goal, among which the best are cellular phone (commonly known as “Big Brother”), public cordless phone (CT2), and wireless paging (BB). The first two can achieve two-way conversation, is the ideal communication tool, but such systems are more expensive. Wireless paging system with the system structure is simple, fast networking, cheap, flexible and convenient to use and so on, so the most rapid development. Wireless paging is a one-way transmission to find
