本文阐述了在计划和设计诸如执法部门和电气公司(即供配电公司)等大机构普遍采用的专用无线电话系统时应考虑的一些因素.对各种结构的无线网络和传信原理作了比较,发现,采用集成电路(模拟电路和逻辑电路)这一现代先进技术获得的改进极令人关注。文中介绍了ITALTEL的RTM101和RTD106两种无线电话系统,这两系统是专为意大利的执法部门和电气公司研制的。RTM101系统是一个独立的话务员控制系统,而RTD106系统拟以ITALTEL ATE—ESK自动电话交换台为基础来与网络联成一体.
This article describes some of the factors that should be considered when planning and designing a dedicated radiotelephone system commonly used by major agencies such as law enforcement agencies and electrical companies (ie, power distribution companies). The principles of wireless networks and signaling principles for various architectures In comparison, it has been found that the improvements obtained using modern advanced technologies such as integrated circuits (analog circuits and logic circuits) are extremely interesting. This article describes ITALTEL’s RTM101 and RTD106 two wireless telephone systems, the two systems are designed for the Italian law enforcement agencies and electrical companies developed. The RTM101 system is a standalone operator control system and the RTD106 system is intended to be networked with the ITALTEL ATE-ESK automatic telephone exchange.
