8.2. PCB Layout Design Notes

The module should be placed as much as close to PCB’s edge. The module
internal antenna should be close to PCB’s edge as much as possible. The
module antenna area’s all layers are copper prohibited.

No power supply or other wiring should pass through antenna bottom.
 The antenna should be placed far away from interference (such as crystal) as
much as possible.
