we have a product which has radio of 1W maximum output power , we have sent product for FCC through party lab, and they certified the product with 18 dbm only. So we get the certificate with only 18 dbm.
But in field we need to use more power like 25 dbm. So can we use this power even if we certified the module at 18 dbm or we need to repeat the whole FCC test again.
