■Intelligent Channel Allocation

The trunking system offers a higher call success rate compared to conventional systems with the same number of channels and users, ensuring reliable communication. Alternatively, with the same number of channels and call success rate, the trunking system can accommodate significantly more users (up to twice as many).


■Comprehensive Functionality
The system supports various communication methods, including emergency alerts, group calls, private calls, all calls, priority calls, status calls, short-data calls, and long-data calls. It allows users to be assigned in different priority levels, ensuring that critical users have the highest communication reliability. 
The dispatch console also supports features such as GPS positioning, voice recording, remote stun, remote kill, and remote activation.


■Fast Connection and Strong Fault Tolerance
The communication base station operates with dynamic operation, where any repeater unit can serve as a control unit. If the current control unit fails, another repeater unit can take over, ensuring the base station remains fully operational.

■Real-Time Monitoring
The system continuously monitors the operating status of each channel repeater, providing users with reliable communication and optimal performance through real-time data. In case of unexpected faults in any repeater, the recorded channel data serves as a valuable reference for troubleshooting.

■Exceptional Adaptability
The system's components are compactly structured, facilitating installation, transportation, and maintenance for everyday communication dispatch. After undergoing various professional assessments and testing in diverse complex environments, it demonstrates excellent pressure resilience and adaptability to meet the emergency communication needs of users in various scenarios.
