Networking Mode

Municipal Emergency Response Network

The district/county level trunking systems, after completion, can be linked up to the municipal network, to achieve connection between the municipal center and districts. And the municipal network is linked up to the provincial network. This three-level interconnection is a highly efficient trunked system that can achieve cross-department& cross-regional cooperation in an emergency response scenario.
