专网从窄带迈向宽带是必由之路

The Right Way from Narrowband to Broadband for the Private Network

随着公众网通信从4G开始迈向5G,数字集群专网也在逐步向宽带多媒体方向演进,为全面走向宽窄带奠定了基础。首先提出了专网宽窄带融合是必然趋势,介绍了我国B-TRUNC标准和国际主流标准,随后分析了宽窄带融合中的服务对象,最后总结出在宽窄带技术融合的进程中,宽带专网要快速发展,需深入了解行业特点、了解任务关键型用户的需求,从而有针对性地建设适合行业特点的应用平台。

With the development of public network communications from 4G to 5G, the digital trunking private network is gradually evolving towards broadband multimedia, which lays the foundation for the overall movement to broadband and narrowband. Firstly, it is pointed out that narrowband and broadband convergence of private networks is an inevitable trend, and the B-TRUNC standard in China and the mainstream international standards are introduced. Then, the service objects in the process of broadband and narrowband convergence are analyzed. Finally, it is concluded that, in order to develop rapidly broadband private networks, it is important to know the industrial characteristics and the demands of mission-critical users in the process of broadband and narrowband technology convergence, and construct the application platform suitable for the industrial characteristics accordingly.
