GSM -R D ownlink  centre frequency f DL = 921  MHz + 𝑛×0.2 MHz1 where 
{𝑛∈ℤ | −7≤𝑛≤19}

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 e. i.r.p. for RMR BS 
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.
