移动中继系统(例如,每信道对有24条话路,频率范围为200至1000MH_2的FM200系统)有着广泛的用途。它适用于时间紧迫的任务,譬喻说救灾。紧急的临时性线路突击抢修和移动网内的日常通信。在大型通信网中,主要是当无法提供固定中继系统所需要的工作室时,它可承担用户电报业务。FM200中继系统是AEG—德律风根公司和西门子股份公司联合研制的。使用移动中继系统的前提是通讯装置要易于操作和维修、坚固并能拆成单件,此外还要经受得住运输和操作中不断变坏的气候条件的考验。电气性能方面在超过标准通信技术的条
Mobile trunking systems (for example, FM200 systems with 24 sessions per channel pair and 200 to 1000 MHz frequency range) have a wide range of uses. It applies to time-critical tasks, such as disaster relief. Urgent temporary line raid repair and daily communication within the mobile network. In a large communications network, it is primarily for subscribers’ telegraph services when it is not possible to provide the required studio for a fixed-trunk system. The FM200 relay system was jointly developed by AEG-Telefunken and Siemens AG. The premise for using the mobile relay system is that the communication device is easy to operate and maintain, strong and capable of being disassembled into a single unit, in addition to being subjected to the deteriorating climatic conditions of transport and operation. Electrical performance is beyond the standard of communications technology
