Hi Stephen,
One thing to remember is that “must not be co-located” really just means “must not be co-located without some additional effort” For example, co-locating two modules and then calculating the new combined RF Exposure MPE value to verify that the product still meets the requirements, would be acceptable. It does not necessarily mean a C2PC is needed, for example. I think you’re right that 20 cm is ‘good guidance’ with regard to RF Exposure. But if your modules are 20.5cm apart, you might still want to consider the overall compliance of that final product… and a co-located MPE calculation is not too hard. Thanks, Michael.

What is the minimum separation distance allowed for another transmitter? I recall 20cm but can't find where it is documented.
