The Recommended Separation Distance is chosen to give significant compliance margin in all
cases. It is also chosen so that a given item (bare module, reflector, or LENS) always has the
same distance, regardless of frequency band, to simplify remembering and following exposure
distances in the field.
These are conservative distances:
 They are along the beam direction (the direction of greatest energy).
Exposure to the sides and back of the module is significantly less.
 They meet sustained exposure limits for the general population (not just
short-term occupational exposure limits), with considerable margin.
 In the reflector cases, the calculated compliance distance d is greatly
overestimated because the far-field equation models the reflector as a point
source and neglects the physical dimension of the reflector.
