It is possible to SMPS with a wireless circuitry, but you have to use good design principles. You need to study EMC/EMI/SI and this is a big field so I recommend you consult with an engineer who has experience in this field. In general, you need to isolate various subsystems so that they do not interfere with each other. A good book on this subject is:
