The European Communications Committee (ECC) has adopted the "ECC Decision on harmonised conditions for Mobile/Fixed Communications Networks operating in the band 790-862 MHz" [12] applicable for BS operating in band 20. The decision defines a requirement for "Out-of-block BEM baseline requirements for ‘mobile/fixed communications network’ (MFCN) base stations within the spectrum allocated to the broadcasting (DTT) service", where three different cases A, B, and C for protecting broadcasting DTT are defined. These cases can be applied on a per-channel and/or per-region basis, i.e. for the same channel different cases can be applied in different geographic areas (e.g. area related to DTT coverage) and different cases can be applied to different channels in the same geographic area.

For band 20, compliance with the regulatory requirements in Europe referenced above can be assessed based on the manufacturer’s declaration of P_EM,N specified in clause 6.6.3.3, together with the deployment characteristics. Maximum output Power in 10 MHz (P_10MHz) is also declared by the manufacturer. The parameters G_ant and N_ant are deployment specific parameters related to the deployment of the BS, where G_ant is the antenna gain and N_ant is the number of antennas.

For each channel (N) the EIRP level is calculated using: P_EIRP,N = P_EM,N + G_ant + 10*log(N_ant ). The regulatory requirement in [12] limits the EIRP level to the Maximum level in Table G-1 for the protection case(s) defined in the regulation.

Table G-1: EIRP limits for protection of broadcasting (DTT) service

Case	Measurement filter centre frequency	Condition on BS maximum aggregate EIRP / 10 MHz, PEIRP_10MHz (Note)	Maximum Level PEIRP,N,MAX	Measurement Bandwidth
A: for DTT frequencies where broadcasting is protected	N*8 + 306 MHz, 21 ≤ N ≤ 60	PEIRP_10MHz ≥ 59 dBm	0 dBm	8 MHz
	N*8 + 306 MHz, 21 ≤ N ≤ 60	36 ≤ PEIRP_10MHz < 59 dBm	PEIRP_10MHz – 59 dBm	8 MHz
	N*8 + 306 MHz, 21 ≤ N ≤ 60	PEIRP_10MHz < 36 dBm	-23 dBm	8 MHz
B: for DTT frequencies where broadcasting is subject to an intermediate level of protection	N*8 + 306 MHz, 21 ≤ N ≤ 60	PEIRP_10MHz ≥ 59 dBm	10 dBm	8 MHz
	N*8 + 306 MHz, 21 ≤ N ≤ 60	36 ≤ PEIRP_10MHz < 59 dBm	PEIRP_10MHz – 49 dBm	8 MHz
	N*8 + 306 MHz, 21 ≤ N ≤ 60	PEIRP_10MHz < 36 dBm	-13 dBm	8 MHz
C: for DTT frequencies where broadcasting is not protected	N*8 + 306 MHz, 21 ≤ N ≤ 60	N.A.	22 dBm	8 MHz
NOTE: PEIRP_10MHz (dBm) is defined by the expression PEIRP_10MHz = P10MHz + Gant + 10*log10(Nant )
