数字对讲机通信标准分析

Analysis of Digital Radio Communications Standards

专业无线通信技术经历了从常规到集群、从模拟向数字的发展历程。随着专业无线通信用户数量的增加,频谱资源日益紧张,同时用户需求也不断多样化。上述变化推动专业无线通信技术开始向数字技术发展。数字对讲机相比传统模拟对讲机优势明显,成为未来对讲机发展的必然趋势。

The professional wireless commtmication technology has developed from convention to tunking and form analog to digital. With the increase of the professional wireless communication users, the spectrum resources are increasingly nervous, at the same time, the needs of users are changing to diversity. The changes promote the professional wireless communication technology developing to digital technology. Compared to the traditional analog walkie-talkie, the digital walkie-talkie has obvious advantages and it will be the inevitable trend of the future walkie-talkie.
