PART A

TECHNICAL CONDITIONS FOR GSM-R IN 874,4-880,0 MHZ and 919,4-925,0 MHZ BANDS

For GSM-R, the following parameters apply:

GSM-R Downlink centre frequency f DL  = 921 MHz +  n  × 0,2 MHz ( 1 ) where

GSM-R Uplink centre frequency f UL  = f DL  – 45 MHz

GSM-R channel bandwidth is 200 kHz

200 kHz

= 70,5 dBm + (f DL  – 921) × 40/3 dB

f DL  is the centre frequency in MHz

There is no EIRP restriction on GSM-R Base Stations transmitting in the 921-925 MHz frequency band. Formula applicable to f DL  ≤ 921 MHz. To allow higher EIRP the implementation of a coordination procedure or other mitigation measures must be applied.

PART B

TECHNICAL CONDITIONS FOR A SINGLE WIDEBAND RAILWAY MOBILE RADIO (RMR) CARRIER IN 874,4-880,0 MHZ and 919,4-925,0 MHZ BANDS

Technical conditions for RMR Base Stations using wideband technologies

The technical conditions defined in this section are in the form of a block-edge mask (BEM) applicable to wideband RMR Base Stations. The technical conditions defined in this section are valid for a single RMR carrier using wideband technologies. The BEM is developed on the basis that detailed coordination and cooperation agreements would not be required to be in place prior to network deployment. To allow multiple carriers or higher EIRP for RMR Base Stations than stated in the harmonised technical conditions, the implementation of a coordination procedure or other mitigation measures must be applied. Base Stations using active antenna systems are prohibited.

For radio access technologies other than GSM-R, the following parameters apply:

—

The lower edge of the lowest Resource Block shall be ≥ 919,6 MHz

Where relevant techniques are described in harmonised standards or parts thereof the references of which have been published in the Official Journal of the European Union in accordance with Directive 2014/53/EU, performance at least equivalent to the performance level associated with those techniques shall be ensured.
