高速无线数传技术在集群通信系统中的应用

Application of high speed data transmission technology in trunking communication system

根据目前模拟集群移动通信系统的发展和现状,给出了一种在用户现有的系统和链路资源下实现高速无线数据传输的解决方案,即利用移动用户终端,通过现有的无线集群系统或常规无线通信系统的无线信道对用户系统的数据库进行实时访问,以获取所需的数据信息,采用高速无线数传调制解调器芯片MX909,使系统数据传输速率达到9.6kb s。

Based on the development and situation of current analog trunking mobile communication system, this paper presents a solution for the user to achieve high speed data transmission on the basis of the system in exis-(tence) and link resources. That is using the mobile terminal to access the system's user database in real time through wireless trunking system or conventional wireless communication system in existence. By adopting the high speed wireless digital transmission modem chip MX909,the system's transmission rate will reach 9.6 kb/s.
