7.3.1.6 Interference
In addition to antenna performance, other interference from the PCB will also affect the module
performance. In order to ensure the high performance of the module, the interference must be under
control. Suggestions: keep speaker, LCD, CPU, FPC wiring, audio circuit, and power supply away from
the antenna; add appropriate separation and shielding devices, or conduct filtering on the path.
