1 Scope p. 6
The present document is a technical report deals with the use of the Rail Mobile Radio spectrum in the 1900MHz frequency band in CEPT countries which are subject to the ECC Decision (20)02 [1] for the use by the railways. The purpose is to gather the relevant background information and studies in order to address all the necessary precautions to make the unpaired spectrum of 1900-1910MHz usable for 5G NR.
