High-speed railway GSM-R

PRODUCT INTRODUCTION

The GSM-R communication frequency bands is essential for the normal operation of high-speed railways.With the rapid growth of the operating mileage of national high-speed railways,the importance of radio support for the frequency bands has gradually become prominent.This system captures,analyzes,identifies,and classifies various signals around railways through dedicated radio monitoring stations along the line.It is capable of comprehensively,real-timely,and finely grasping the basic condition and spectrum changes of radio frequency stations within the protection zones along the high-speed railway,achieving intelligent monitoring,early warning,and protection of the GSM-R specialized communication frequency bands.

GSM,GSM-R,CDMA,LTE-R,5G-R Systems:Deep, Comprehensive,and Accurate Decoding Capabilities.

The system is able to deeply,comprehensively,and accurately decode GSM,GSM-R,CDMA,LTE-R,and 5G-R systems.In addition,it is capable of monitoring the signal intensity of the carrier in the modulation spectrum of the GSM-R downlink frequency band's BCCH channel,that of the downlink frequency band's TCH channel no matterthe communication link is established ornot,and the strength of each channel in the uplink frequency band under the same condition at actual time.
An advanced interference detection algorithm based on signal characteristics

According to the characteristics of GSM-R communication,the system not only utilized traditional level-based statistical methods,but also employs the company's unique signal feature-based interference detection manners.By making use of the domains of time,frequency,modulation,and code, along with other characteristics of signals,interference detection isachieved more sensitively and accurately
High concurrency,supporting simultaneous data collection from over 150 monitoring stations

The system supports simultaneous data collection from more then 150 monitoring stations on a single node and data storage in high concurrency conditions.
Active monitoring mode,easy to assign monitoring tasks

The GSM-R monitoring system adopts an active monitoring mode,which means that users can simultaneously assign tasks to multiple stations. Then the monitoring stations will automatically work when powered on,actively realizing GSM-R frequency band monitoring.
Perfectly integrated with the daily work of National Radio Administration Bureau

The GSM-R monitoring equipment and software provided by the company not only have monitoring and decoding functions for dedicated frequency bands such as GSM,GSM-R,CDMA,LTE-R,and 5G-R, but also boast full frequency band monitoring capabilities of 20-8000MHz.Additionally,it enables GSM-R monitoring stations to integrate into the existing monitoring network,forming joint monitoring capabilities with other stations and comprehensively expand the coverage of

MAIN FUNCTIONS

Monitor GSM-R uplink and downlink frequencyoperation at actual time
Give an alarmin GSM-R protection frequencyinterference at actual time,and analyze and identify the sources
Track frequency occupancy in ultra short wave frequency bands along high-speed rail lines at actual time
Unpack historical changes in electromagnetic environment around railways and warn of GSM-Rinterference trends
