Cellular Signal Amplification System - Ledatel

Provides a strong and evenly distributed mobile network coverage throughout the vehicle. 
Effective communication is not a luxury – it’s a core necessity.

Distributed Antenna Systems (DAS) provide an even coverage of the cellurar signal in the whole vehicle. This allows passengers to use a stable connection during domestic and international travel.

LEO Rail Central

Our central application is used to support distributed GSM/LTE signal amplification systems. This comprehensive operation-maintenance platform lets users configure devices and manage potential failures. It also uses open SNMP interface to forward alerts via email and text messages. With this fully integrated platform, users can monitor and control the network from a single central location or from local branch offices.

For analytical purposes, it is possible to export data in the open CSV format.

The task scheduler lets users automate recurring tasks such as performance data download.

Main features, tasks, and functionalities

  • The modular (independent RF cards), scalable architecture of the amplifier allows users to easily and quickly modernize and expand the configuration through additional RF cards. Software functionality upgrades don’t require extra installation space or device replacement
  • GPS-based repeater reconfiguration at international borders
  • Remote management and monitoring
  • Amplified operator bands selection
  • Compliance with the requirements of RED 2014/53/EU
