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. |

Additional baseline power limits for non-AAS and AAS base stations f8 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. | |||||
