集群通信经历了从无线对讲系统、模拟集群专网、数字集群系统的发展历程,随着数字集群阶段各种先进成熟的技术陆续推出,集群通信市场从小规模专网向大规模专网与集群公网的方向演进。目前在国内外市场中比较有影响力且被国际电联(ITU)通过的数字集群标准有:欧洲电信标准协会ETSI的TETRA(陆地集群无线通信)、美国Motorola的iDEN(集成数字增强型网络)、中国提交的GoTa(全球开放式集群通信架构)数字集群标准。从市场应用与技术指标来 Trunking communications has gone through the development of wireless intercom systems, analog trunking private networks and digital trunking systems. With the introduction of various advanced and mature technologies in the digital trunking stage, the trunking communications market has expanded from small-scale private networks to large-scale private networks and clusters The direction of public network evolution. At present, the influential standards in the domestic and overseas markets and adopted by the ITU are: TETRA (Terrestrial Cluster Wireless Communication) of the European Telecommunications Standards Institute ETSI, iDEN (Integrated Digital Enhanced Network) of Motorola of the United States, , The GoTa (Global Open Cluster Communication Architecture) digital trunking standard submitted by China.
