# Commission Implementing Decision (EU) 2019/784 of 14 May 2019 on harmonisation of the 24,25-27,5 GHz frequency band for terrestrial systems capable of providing wireless broadband electronic communications services in the Union (notified under document C(2019) 3450) (Text with EEA relevance), Division Figure 2: Illustration of a block edge mask

Extent: E+W+S+N.I.

No harmonised in-block power limit is specified. Tables 2 and 3 assume synchronised operation. Unsynchronised or semi-synchronised operation also necessitates the geographical separation of neighbouring networks. Tables 4 and 6 specify out-of-band power limits for base stations and terminal stations respectively to ensure the protection of the Earth Exploration Satellite Service (EESS) (passive) in the 23,6-24,0 GHz frequency band. Table 5 provides an additional technical condition for base stations to facilitate co-existence with satellite systems in the earth-to-space Fixed Satellite Service (FSS) and in the Inter-Satellite Service (ISS).

Definition
In-block
Assigned spectrum block for which the BEM is derived.
Baseline
Spectrum within the 24,25-27,5 GHz frequency band used for terrestrial wireless broadband electronic communications services, not including the operator's block under consideration and corresponding transitional regions.
Transitional region
Spectrum adjacent to an operator's block.
Additional baseline
Spectrum within bands adjacent to the 24,25-27,5 GHz frequency band, where specific power limits apply with respect to other services or applications.

Base station additional baseline power limit
Member States shall not allow new deployments of terrestrial systems capable of providing wireless broadband electronic communications services in the frequency range 22-23,6 GHz, in order to ensure the appropriate protection of the Earth Exploration Satellite Service (passive) and the Radio Astronomy Service in the 23,6-24 GHz frequency band in conjunction with the limit applicable after 1 January 2024 .
This limit applies to base stations brought into use after 1 January 2024 . This limit does not apply to base stations that have been brought into use prior to that date. For those base stations, the limit of – 33 dBW/200 MHz continues to apply after 1 January 2024 . Member States shall consider additional measures to assess and mitigate the aggregate impact of those base stations in relation to their obligation under Article 3(a) regarding the Earth Exploration Satellite Service (passive). Such measures include adaptation of the size of assigned blocks, the antenna configuration, the in-block power or the penetration of equipment.
