The length and detail of your response indicates otherwise!

Well, it surprises me. The emissions from most of these products (except
laptops) are quite weak. Since these are said to present a significant
threat, I wonder that different systems within the aircraft's own
electronic installation can practicably be prevented from interacting
adversely.

Of course not, but resistance to in-band interference can be very high
if suitable modulation schemes and signal formats are used.
