TIA TSB-92-A PDF

This TSB establishes and documents methods and procedures of evaluation to establish compliance of fixed station cabinet emission levels with respect to the Federal Communications Commission (FCC) electromagnetic exposure (EME) limits. Specifically the EME characterization is of box level equipment only, e.g., a fixed station, control station, or similar equipment. This TSB is not a substitute for a complete transmitter site environmental assessment (EA) by means of computational methods or site measurement or a combination of these two means. A limit case analysis based on the 47 CFR part 90 certification requirements for spurious emissions limits included herein shows that certified equipment at the box level is within the FCC maximum permissible exposure (MPE) limits.
