Why does the LTE module require a “Contains FCC ID label”?

The LTE transmitter is authorized under its own FCC ID, and the host radio compliance relies on that existing certification rather than a full host-level authorization of the LTE RF chain. The LTE module, therefore, remains a separately authorized transmitter, and the host device is not the grantee of that RF function. The FCC requires labeling in this situation to maintain clear traceability between the host product and the LTE module certification. For that reason, the LTE module must be identified on the product using a Contains FCC ID label.
