PARAMETERS REFERRED TO IN ARTICLE 2(1) AND 2(2)
A. GENERAL PARAMETERS
1.
The mode of operation within the 1 427-1 517 MHz frequency band shall be limited to base station (“downlink-only”) transmission.
2.
Block sizes within the 1 427-1 517 MHz frequency band shall be assigned in multiples of 5 MHz. The lower frequency limit of an assigned block shall be aligned with or spaced at multiples of 5 MHz from the lower band edge of 1 427 MHz.
3.
Base station transmission shall comply with the technical conditions (block edge masks) set out in this annex.
B. TECHNICAL CONDITIONS FOR BASE STATIONS — BLOCK EDGE MASK
The following technical parameters for base stations called “block edge mask” (BEM) shall be used in order to ensure coexistence between neighbouring networks in the absence of bilateral or multilateral agreements between operators of such neighbouring networks. Less stringent technical parameters, if agreed among the operators or administrations concerned, may also be used provided that these parameters comply with the technical conditions applicable for the protection of other services or applications, including in adjacent bands or subject to cross-border obligations.
The BEM is an emission mask that is defined as a function of frequency in relation to the edge of a block of spectrum for which rights of use are granted to an operator. It consists of in-block and out-of-block power limits. The in-block power limit is applied to a block owned by an operator. The out-of-block power limits are applied to spectrum used for WBB ECS within the 1 427-1 517 MHz frequency band which is outside a block granted to an operator. They are set out in Table 2. The out-of-band power limits are applied to spectrum outside the portion of the 1 427-1 517 MHz frequency band, which is used for WBB ECS at national level.
Furthermore, coexistence power limits are defined for wireless broadband electronic communications services (WBB ECS) within the 1 427-1 517 MHz band in order to ensure compatibility between these services and other radio services or applications, including when a portion of the 1 427-1 452 MHz and the 1 492-1 517 MHz bands is not designated for WBB ECS. The co-existence power limits with regard to services or applications in the adjacent bands (i.e. outside the spectrum used for WBB ECS) are set out in Table 3, 4, and 5 and also cater for national flexibility in assigning spectrum for WBB ECS within the 1 427-1 517 MHz frequency band pursuant to this Decision.
Additional technical or procedural measures ( 1 ) or both may be applied at national level to ensure coexistence with services and applications in the adjacent bands.
In-block requirements
An in-block equivalent isotropically radiated power (EIRP) limit for base stations is not obligatory except for the 1 512-1 517 MHz frequency block, for which such a limit is given in Table 1. For frequency blocks other than the 1 512-1 517 MHz frequency block, Member States may set an EIRP limit not exceeding 68 dBm/5 MHz which can be increased for specific deployments, for example for the aggregated use of spectrum within the 1 427-1 512 MHz band and spectrum in lower frequency bands.

These requirements are intended to ensure compatibility between WBB ECS operating in the 1 512-1 517 MHz frequency block and mobile satellite services operating in the 1 518-1 525 MHz frequency band.

Explanatory note to Table 3
This requirement is intended to protect radio astronomy and passive earth exploration satellite services in the 1 400-1 427 MHz passive frequency band from WBB ECS operating in the 1 427-1 452 MHz frequency band, including when only a portion of this frequency band is assigned for WBB ECS. Further national measures may be needed to improve protection of radio astronomy observations in passive frequency band 1 400-1 427 MHz from WBB ECS.

Explanatory note to Table 4
These requirements are intended to provide appropriate protection of mobile satellite services operating in the 1 518-1 559 MHz frequency band, in particular at sea ports, airports and search and rescue ground stations of the mobile satellite service, from WBB ECS operating in the 1 492-1 517 MHz frequency band, including when only a portion of this frequency band is assigned for WBB ECS. Further national measures may be needed to improve protection of mobile satellite services in the band 1 518-1 559 MHz.

Explanatory note to Table 5
These requirements are applicable when WBB ECS are not deployed either below 1 452 MHz or above 1 492 MHz, or both. They are intended to ensure compatibility of WBB ECS within the 1 452-1 492 MHz frequency band with coordinated fixed links, mobile services and aeronautical telemetry services limited to ground stations, deployed in adjacent frequency bands below 1 452 MHz or above 1 492 MHz.
When WBB ECS are deployed within the blocks immediately below 1 452 MHz, the limits indicated in Table 5 for frequencies below 1 452 MHz are not applicable. When WBB ECS are deployed within the blocks immediately above 1 492 MHz, the limits indicated in Table 5 for frequencies above 1 492 MHz are not applicable. This is without prejudice to the out-of-band requirements laid down in Tables 3 and 4 and to the out-of-block requirements laid down in Table 2.
