Etelm Succesfully Tests TETRA in Record Time on Paris Express Line 15 South

This week for the first time, radio communications on the ETELM Tetra multisite network at the SMR in Champigny-sur-Marne to cover the rolling tests of the Paris Express line 15 South went live.

Especially in this project, beyond the technical aspects, the human performance is to be lauded. In a complex railway environment, less than two months passed between notice and system commissioning..    This was possible because of the effective coordination of the EGIS teams and the real desire of all the direct partners of this project to succeed: SGP, COLAS RAIL, JNOVENERGIES, FASS TRANSMISSIONS.

Another important role was 'played' by the team ARCEP and ANFR as radio frequencies were assigned in recond time.
