Project ERA - Interoperability tests between LTE and GSM-R for railway operation applications based on SDR components
Project Description
A special GSM mobile radio system (GSM-R) is currently operated for radio-based transmission in the railway sector. Today, this technology reaches its performance limits, particularly at highly frequented railway station areas. In the future, the mobile communication standard LTE promises to solve this shortages. To test the feasibility of this technology migration, interoperability testing under laboratory conditions are necessary.
Working Package ITVS
ITVS work was the technical concept and realization for measurements on LTE/GSM-R interference in the frequency range of current railway transmission systems by using state of the art Software Defined Radio equipment. An experimental lab setup was built for this research. NI USRPs work as dedicated base stations both for LTE and GSM-R. A NI PXI system is used as an interference signal generator with its capability to record and playback synchronous dual-channel signals (LTE, GSM-R). Selected results of the analyses on the basis of specific conditions for LTE (carrier bandwidth of 1.4 MHz) and GSM-R are investigated.
