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.
•
In the case of collocated APs, they assume all APs are oriented in the same direction,
which is a worst-case calculation.
•
They meet or exceed sustained exposure limits for the general population (not just
short-term occupational exposure limits).
•
The calculated compliance distance d is overestimated because the far-field equation
models the antenna(s) as a point source and neglects the physical dimension of the
antenna(s).
