Masks consistency check - making tolerance margins editable by the SEAMCAT user
STG#66 - Document STG(20)014 - in order to ensure that the used emission and blocking masks comply with the corresponding system settings, i.e. ILT bandwidth and VLR reception bandwidth, consistency checks are implemented. The current implementation applies ‘tolerance margins’ which are set to 0.2 dB for the relative powers of the emission masks and 1.5 dB for bandwidth values. Document STG(20)014 proposes to have ‘tolerance margins’ editable, and to suppress the consistency information about the antenna heights generated by the Extended Hata propagation model for the currently running instance of SEAMCAT and provides patches for this proposal. Additional information for the definition of the ITU Radio Regulations for unwanted emissions can be found in document STG(19)038. STG discussed about source of defined values, difference of effective and allocated system bandwidth and consistency checks.
STG#66 discussed the issue and left the decision for some of the following STG meetings, after STG members will have time for further consideration and thinking on this matter. AP: STG members to consider and decide at one following STG meetings.
Attached document gives explanation of the issues, 2 patches attached v.5.4.0
