ANNEX
PART A
TECHNICAL CONDITIONS FOR GSM-R IN 874,4-880,0 MHZ and 919,4-925,0 MHZ BANDS
GSM-R channel bandwidth |
Maximum e.i.r.p. |
200 kHz |
= 70,5 dBm + (fDL – 921) × 40/3 dB |
fDL is the centre frequency in MHz There is no e.i.r.p. restriction on GSM-R Base Stations transmitting in the 921-925 MHz frequency band. Formula applicable to fDL ≤ 921 MHz. To allow higher e.i.r.p, the implementation of a coordination procedure or other mitigation measures must be applied. |
PART B

Technical conditions for RMR Base Stations using wideband technologies
RMR channel bandwidth |
Maximum e.i.r.p. |
For any channel bandwidth |
The following value may be used in case an upper bound is desired: = Min {65 dBm/channel, Maximum e.i.r.p. specific to the channel bandwidth} |
RMR channel bandwidth |
Maximum e.i.r.p. |
5,6 MHz |
= 62 dBm/5,6 MHz |
5 MHz |
= 64,5 dBm/5 MHz + (fDL – 922,1) × 40/3 dB |
fDL is the centre frequency in MHz. NB-IoT in-band operation mode without power boost is allowed. NB-IoT guard-band operation mode and in-band operation mode with power boost are not allowed. |
RMR channel bandwidth |
Maximum e.i.r.p. |
1,4 MHz |

200 kHz (Note 2) |
= 70,5 dBm/200 kHz + (fDL – 921) × 40/3 dB (Note 3) |
fDL is the centre frequency in MHz. Note 1: Formula applicable to fDL ≤ 921,7 MHz. No specific e.i.r.p. restriction above. Note 2: Applicable to NB-IoT standalone operation mode, which is made of one Resource Block. Note 3: Formula applicable to fDL ≤ 921,0 MHz. No specific e.i.r.p. restriction above. |
MHz from block edge (919,4-925 MHz) |

32,5 dBm/200 kHz |
0,2 ≤ Δf < 1 |
14 dBm/800 kHz |
