Dual-Mode Train Tail Communication Onboard Unit

Application: Railway freight train tail safety protection and communication

The M4224G Dual-Mode Train Tail Communication Onboard Unit is a new-generation digital safety protection device for freight train tails. It is the first product to simultaneously integrate 400MHz digital two-way radio technology and GSM-R technology into railway train tail safety protection systems. This innovation effectively addresses issues such as severe same-frequency and adjacent-frequency interference in traditional analog train tail communication systems, as well as communication challenges in complex terrains like mountainous areas and tunnels, ensuring stable and reliable train tail communication. The product plays a significant role in safeguarding railway transportation safety and improving operational efficiency.

It has been widely adopted by railway bureaus and companies across China and has also been exported to overseas markets, demonstrating excellent performance in practical applications. Aligned with the industry trend of transitioning from analog to digital two-way radio communication and in line with national policies promoting digital two-way radio technology, this product actively fosters and advances the application and adoption of digital two-way radio technology in the railway communication sector.
