context: In CEPT ECC decision (13)03 [8], a BEM (Block Edge Mask) has been introduced as a regulatory requirement in terms of EIRP for the DL band within 1452-1492 MHz. In ECC PT1(13)042 [9] it was proposed to derive the out-of-block BEM within 1452-1492 MHz based on the 3GPP MSR operating band unwanted emission for BS. This BEM is applicable for both E-UTRA and UTRA technologies. ECC PT1(13)042 [9] also refers to CEPT Report 39, where a BEM is derived for 2GHz based on BS to UE interference scenarios. In this report, the assumed antenna gain is 17dBi. The BEM out of block EIRP limits in the LRTC in CEPT ECC decision (13)03 [8] are specified per antenna. A BS fulfilling the operating band unwanted emission as defined by 3GPP in the MSR specifications does not automatically comply with the BEM as defined by CEPT as the latter is subject to the antenna gain. However, this mask is the most suitable as it was used as the baseline mask by CEPT to derive the BEM out of block EIRP requirements.
description: The Fixed Service (FS) is a simulated environment used for testing and evaluating the performance of mobile communication systems. It specifically focuses on scenarios involving far scatterer clusters to model and analyze signal propagation and delay characteristics in a controlled manner.
explanation: FS is classified as a Testing Environment because its primary function is to provide a controlled and simulated setting for evaluating the performance of mobile communication systems.
