1  Scope  p. 6

The present document is a technical report deals with the use of the Rail Mobile Radio spectrum in the 900MHz frequency band, which was assigned by the ECC Decision (20)02 [1] for the use by the railways in Europe.The purpose is to gather the relevant background information and studies in order to address all the necessary precautions to make the paired spectrum of 874.6-800/919.4-925MHz usable for 5G NR.
