div.yiv1807988800WordSection1 {}#yiv1807988800 The latest chatter I gathered on 
this topic is that the FCC considers collocated as "in the same enclosure".  
Indications are that any reference to <20cm being considered collocated has 
been set aside.     Bill    From: Michael Derby [mailto:micha...@acbcert.com]

Subject: Re: [PSES] Co-located modules    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.          From: Stephen Whalen [mailto:scwha...@bellsouth.net]

Subject: [PSES] Co-located modules    All, For a module that has "must not be 
co-located" restriction on FCC grant.  What is the minimum separation distance 
allowed for another transmitter?  I recall 20cm but can't find where it is 
documented.    Regards, Stephen -
