RF Exposure ID LRU500i-FCC 1/1
FCC ID: PJM LRU500I
IC: 6633A-LRU500I
Date : 2019-03-22

RF Exposure Compliance Requirement
ID LRU500i-BD-FCC / ID LRU500i-PoE-FCC / ID MAX.U500i-FCC

The maximum permissible exposure (MPE) for general population is defined as 0.6mW/cm2
( f / 1500, FCC OET Bulletin 65, Supplement B). The distance from the transmitting antenna
where the exposure level reaches the maximum permitted level is calculated using
equation (1):

EIRP
S= (1)
4 ⋅π ⋅ R2
where: S = Power density 0.6mW/cm2
EIRP = Power output of an isotropic antenna 4W
R = Distance to the centre of the radiation of the antenna

Solving equation (1) the minimum distance at which a person must keep away in a
uncontrolled exposure is

R = 23cm

The maximum permissible exposure (MPE) for controlled exposure is defined as 3mW/cm2
( f / 300, FCC OET Bulletin 65, Supplement B). Solving equation (1) where S = 3mW/cm2 the
minimum distance at which a person must keep away in a uncontrolled exposure is

R = 10,3cm
