# Commission Implementing Decision (EU) 2019/235 of 24 January 2019 on amending Decision 2008/411/EC as regards an update of relevant technical conditions applicable to the 3 400-3 800 MHz frequency band (notified under document C(2019) 262) (Text with EEA relevance), Division Figure: Example of base station BEM elements and power limits Extent: E+W+S+N.I. Table 1 Definition of BEM elements BEM element Definition In-block Refers to a block for which the BEM is derived. Baseline Spectrum within 3 400-3 800 MHz used for WBB ECS, with the exception of the block assigned to the operator and the corresponding transitional regions. Transitional region Spectrum within 0 to 10 MHz below and 0 to 10 MHz above the block assigned to the operator. Transitional regions do not apply to TDD blocks assigned to other operators, unless networks are synchronised. The transitional regions do not apply below 3 400 MHz or above 3 800 MHz. Additional baseline Spectrum below 3 400 MHz and above 3 800 MHz. Restricted baseline Spectrum used for WBB ECS by networks unsynchronised or semi-synchronised with the operator's block in question. Table 2 In-block power limit for non-AAS and AAS base stations BEM element Frequency range Power limit for non-AAS and AAS base stations In-block Block assigned to the operator Not obligatory. Table 3 Baseline power limits for non-AAS and AAS base stations with synchronised network operation PMax is the maximum mean carrier power in dBm for the base station measured as e.i.r.p. per carrier per antenna PMax′ is the maximum mean carrier power in dBm for the base station measured as TRP per carrier in a given cell In a multi-sector base station, the radiated power limit applies to each one of the individual sectors. BEM element Frequency range Non-AAS e.i.r.p limit AAS TRP limit Baseline Below – 10 MHz offset from lower block edge Above 10 MHz offset from upper block edge Within 3 400-3 800 MHz Min(PMax – 43, 13) dBm/(5 MHz) per antenna Min(PMax′ – 43, 1) dBm/(5 MHz) per cell Table 4 Transitional region power limits, for non-AAS and AAS base stations with synchronised WBB ECS network operation PMax is the maximum mean carrier power in dBm for the base station measured as e.i.r.p. per carrier per antenna PMax′ is the maximum mean carrier power in dBm for the base station measured as TRP per carrier in a given cell In a multi-sector base station, the radiated power limit applies to each one of the individual sectors. BEM element Frequency range Non-AAS e.i.r.p limit AAS TRP limit Transitional region – 5 to 0 MHz offset from lower block edge or 0 to 5 MHz offset from upper block edge Min(PMax – 40, 21) dBm/(5 MHz) per antenna Min(PMax′ – 40, 16) dBm/(5 MHz) per cell Transitional region – 10 to – 5 MHz offset from lower block edge or 5 to 10 MHz offset from upper block edge Min(PMax – 43, 15) dBm/(5 MHz) per antenna Min(PMax′ – 43, 12) dBm/(5 MHz) per cell Table 5 Restricted baseline power limits for non-AAS and AAS base stations with unsynchronised and semi-synchronised WBB ECS network operation In a multi-sector base station, the radiated power limit applies to each one of the individual sectors. BEM element Frequency range Non AAS e.i.r.p limit AAS TRP limit Restricted baseline Unsynchronised and semi synchronised blocks, below the lower block edge and above the upper block edge, within 3 400-3 800 MHz – 34 dBm/(5 MHz) per cell – 43 dBm/(5 MHz) per cell Table 6 Additional baseline power limits for non-AAS and AAS base stations below 3 400 MHz for country-specific cases Alternative measures may be required on a case by case basis for indoor AAS base stations on a national basis. In cases where Member States have already implemented a guard band when issuing licences for terrestrial systems capable of providing WBB ECS before the adoption of this Decision and in accordance with Commission Decision 2008/411/EC, those Member States may apply the additional baseline only below such guard band, provided it complies with the protection of radars in the adjacent band and with cross-border obligations. In a multi-sector base station, the radiated power limit applies to each one of the individual sectors Case BEM element Frequency range Non-AAS e.i.r.p limit AAS TRP limit A Member States with military radiolocation systems below 3 400 MHz Additional baseline Below 3 400 MHz – 59 dBm/MHz per antenna – 52 dBm/MHz per cell B Member States with military radiolocation systems below 3 400 MHz Additional baseline Below 3 400 MHz – 50 dBm/MHz per antenna C Member States without adjacent band usage or with usage that does not need extra protection Additional baseline Below 3 400 MHz Not applicable Not applicable Table 7 Additional baseline power limits above 3 800 MHz for base stations for coexistence with FSS/FS PMax is the maximum mean carrier power in dBm for the base station measured as e.i.r.p. per carrier per antenna PMax′ is the maximum mean carrier power in dBm for the base station measured as TRP per carrier in a given cell In a multi-sector base station, the radiated power limit refers to the level corresponding to each one of the individual sectors BEM element Frequency range Non-AAS e.i.r.p limit AAS TRP power limit Additional baseline 3 800-3 805 MHz Min(PMax – 40, 21) dBm/(5 MHz) per antenna Min(PMax′ – 40, 16) dBm/(5 MHz) per cell 3 805-3 810 MHz Min(PMax – 43, 15) dBm/(5 MHz) per antenna Min(PMax′ – 43, 12) dBm/(5 MHz) per cell 3 810-3 840 MHz Min(PMax – 43, 13) dBm/(5 MHz) per antenna Min(PMax′ – 43, 1) dBm/(5 MHz) per cell Above 3 840 MHz – 2 dBm/(5 MHz) per antenna – 14 dBm/(5 MHz) per cell --- Source: https://www.legislation.gov.uk/eudn/2019/235/annex/division/C/division/Figure (the official version) Page: https://openlegislation.uk/eu-decision-2019-235/annex/division-C/division-Figure Contains public sector information licensed under the Open Government Licence v3.0.
