3、If module needs reflow, pay attention to reflow profile.
4、Area below the ANT of this module, should not use polygon.
5、ANT of this module should be far away from other circuit.
6、Module should be placed as far as possible away from the other low frequency circuits or
digital circuits.
7、Module is plugged into a power supply for recommend the use of magnetic beads in
isolation.
8、If there are other internal band wireless module in your product, frequency should be
reasonable planning, take the shielding measures, such as reduce the influence of harmonic
