Model : HME-LD
1. Summary
It’s hard to check the system personally in the tunnels because of running trains. HME-LD is a wireless observation device that you can install at the underground or at the end of the tunnel. It is installed at the end of LCX, RCX so that it can monitor and observe RSSI using radio frequencies. Therefore, yourself or an administrator can check the equipment inside the tunnel at the remote site.
2. Features & Functions
- -Distribution for each FM Radio (88~108MHz), VHF Station communication (146~174MHz), Fire Communication /Train Protection (440~470MHz), Ground-wave DMB(174~214MHz), TRS(800~900MHz)
- -Appropriate Solution for train environment which has various types of communication, offering compatibility for Digital TRS Repeater & other repeaters
- -Applying for NMS, and Observing & control function in tunnel by interlocking with BDA
