Robert The difference lies in the licensed or unlicensed aspects of the device. It does not matter if you are compliant to the limits or not, simply interfering with a licensed band means you are not compliant to the rules. Licensed bands are protected bands, while they can interfere with unlicensed devices, unlicensed devices cannot interfere with licensed bands. They can demand that you cease operation and that demand will be backed by the FCC and its rules. You have no choice but to either fix the problem of interference or cease operation Thanks

Our equipment is EMC tested to CISPR Class A for business only use, and at 780 Mhz our radiated Level at 3Meters is under the Class A limit of 57 dB at 780 Mhz. Question is, can the complaining company legally demand that we drop the signal further, they may be looking at a necessary reduction of current level by 20 dB lower.
