problems caused by RF part of the module. Use good consideration to avoid problems arising
from digital signals in the design.
Ensure that signal lines have return paths as short as possible. For example if a signal
goes to an inner layer through a via, always use ground vias around it. Locate them tightly and
symmetrically around the signal vias. Routing of any sensitive signals should be done in the
inner layers of the PCB. Sensitive traces should have a ground area above and under the line.
If this is not possible, make sure that the return path is short by other means (for example
using a ground line next to the signal line).
