Because the RN-42-N does not contain an antenna, it does not carry regulatory approvals.
If designers use Roving Networks recommended design, they can file for a permissible antenna change and use Roving
Networks’ regulatory approvals. The recommended antenna design for the RN-42 is a PCB trace antenna. To meet the
regulatory compliance information, customers must use the trace pattern shown in Figure 6.
