Abstract:

At present, the deployment of industry private networks mainly consists of broadband trunking communication networks and narrowband trunking communication networks. However, with the continuously increasing demand for broadband and visual application scenarios in private networks, and considering multiple factors such as the autonomy of communication systems, existed network deployment, network construction costs, and network service application requirements, the broadband and narrowband converged technology based on trunking private network is proposed. This paper designs a network architecture for the converged technology of broadband trunking communication and narrowband trunking communication, and analyzes the future evolution path of broadband and narrowband converged technology in combination with the development of 5G technology in the industry.

Key words: trunking private network, broadband trunking, narrowband trunking, broadband and narrowband convergence
