Supports 5G signal coverage in train carriages for China's three major carriers: China Mobile, China Telecom, and China Unicom.

Utilizes broadband digital repeater technology to condition and filter received wireless signals, effectively suppressing external noise.

Employs digital Doppler equalization technology, ensuring normal communication within carriages even at train speeds of up to 500 km/h.

Automatically adjusts the signal level inside the carriage based on the distribution of public network signals outside, preventing multipath interference between indoor and outdoor signals.

Enables remote monitoring of carriage coverage quality and equipment status, providing real-time vehicle communication information via BeiDou satellite positioning.

Supports automatic latency compensation and real-time monitoring of interference and useful signals to dynamically adjust transmission power.
