Lower 37 GHz Band and Use of Spectrum Bands Above 24 GHz for Mobile Radio Service

Riepilogo

In this document, the Federal Communications Commission (Commission) seeks comment on three issues: adopting a more stringent emissions limit for Upper Microwave Flexible Use Service (UMFUS) operations above 37 GHz; whether the first phase of the coordination mechanism adopted in the companion final rule, published elsewhere in this issue of the Federal Register, can be enhanced by consideration of additional factors; and whether it might be possible to replace the same coordination mechanism with a dynamic spectrum management system (DSMS). The Commission also proposes to correct an error in a power flux density (PFD) figure in one of its technical rules for UMFUS.
